Make That Point Actually GM did it to compete against the ecoboost. Has nothing to do with Obama. If that was the case, then Ram would have included it in the Hemi and Ford in the Coyote.
Make That Point hemis do have a version of this called multi displacement. It’s more advanced in my opinion and it doesn’t affect performance as much as v4 does
@@skully720 No they didn't. Nobody knew about the Ecoboost until 2009-2010, this engine came out in 2006. Besides, this is not a way to compete with a twin-turbo charged V6.
Bought one for my 07 Avalanche works great.I would recommend this product.Truck started using oil 2 quarts a month from blow back into unfiring pistons in V4. No oil consumption now.
We had a new 2011 silverado 1500 burning oil like crazy because of the v4 mode. Got this same model of obd2 accessory, and 150k miles later, we haven't burned any oil and the truck feels better to drive. Definitely a good investment!
Update : I traded my 2010 Silverado LTZ 5.3, for a 2015 Silverado LTZ 6.2 and brought my range technology disabler over to the new truck. It worked great on my 10, my gas mileage seemed to improve slightly, and oil consumption stopped. The 15, the mileage went down a small amount, oil consumption either slowed down dramatically or stopped. I tested it for 3 weeks with and 3 weeks without. I drive about 100 miles a day 70% are highway miles the rest city driving. Just like the 10, it works great, the engine seems happier, in my mind as a life long drag racer, I don't like the idea of 4 dead pistons and rods putting unnecessary drag on the rest of the engine. I get the concept but if I wanted a 4 cylinder that's what I would have bought. As for the 6.2, I love it, it's a beast, she runs great and sounds good too.
I have 2016 Silverado 5.3 bought Range it works great to keep in v8 mode. I use a pedal commander. The truck has dual exhaust with cats and third cat removed, then each cat piped into one cherrybomb extreme muffler 2in 2out. Pipes run out behind rear wheels. Engine is using cold air intake kn filter.Truck has great sound and power for slightly modded truck. I do however one day a month take range out just for gp. Have no oil loss using a McNally oil seporater 3 line. The range is great. Hey Man great video. .
Worth every cent. I just recently got one for my 2014 Sierra. No more lag when trying to step on the gas during city cruising. The power is always there now. It feels entirely like a different vehicle in town. Also, no more annoying chirp from the muffler flapper.
Not only is it annoying. It also causes lifters to lock down and the possibly wipe the cam. These lifters can only be replaced after removing the heads. Then,if the cam is bad,you have to remove engine mounts so you can lift the engine to remove the oil pan. That's the only way,short of pulling your engine,to get the oil pump from around your crank. A big job.
I had a 2015 Suburban run almost flawlessly from July 4, 2015 (new) through August 4, 2023 when it was totalled in a rearend accident. The cyclinder deactivation was flawless. It had no shakes or sounds and worked to get great milage.
Here is how you DO IT FOR FREE!!! For anybody who doesn’t know you can run these trucks in Manual mode but put it one gear down from the highest gear (5th gear for me, since I have a 6spd) and leave it there when you’re not on the interstate and don’t need the overdrive, and it’ll still act like the normal automatic and stay in V8 mode 100%. And you can shift between Drive and Manual mode in these trucks on the fly with no harm.
Yes. My question is do you have to do anything different or just plug it back in. If you need the computer port. I like my truck as quiet as possible. My 2017 Silverado is working fine so far 26000 avg around 17 + mpg . Should I do this or not?
Just got Range AFM disabler. . I have a 2018 Sierra All Terrain 5.3 8 speed transmission. . Everything stock so far. I have ran two tanks and have not seen any noticeable difference on fuel economy. I have seen better throttle response. It eliminated the intermittent strange jerks the tranny did particular at lower speeds. I spoke with the service manager at my local GM dealer and he said warranty will not be affected. He was curious and wanted me to report on the performance results after about a months use.
I cant wait to try one of these but also FYI not all of the jerking and shuddering is due to this. There is a Torque Converter issue with all of these trucks. GM knows about it but the service guys always try to blow it off. I found the service bulletin from GM and took it in to be serviced and now they are replacing it. When you are informed there is not much they can do or say. EVERYONE should know about these TCC issues, i know we all have felt the shudder like your driving on rumble strips when you go from a coast to tipping back in the throttle.
Cool...yeh, that DoD (4 cylinder mode deal) really upsetted me for years on my 2014 Chevy Silverado 4x4 (5.3L). Finally bought a canned tuner (Diablo i3 inTune) performance tuner module. I was able to disable that DoD, disable the speed limiter, increase throttle response 10%, recalibrate for taller tires, and do their canned "Flex 91 octane" tune. Everything I did was readily apparent (the module "does what it says"). Amazing how the truck runs now. Smoother, better throttle response, better acceleration, and it holds the shifts longer (like a truck should). I was also able to "tweak" the 1-2, 2-3, and 3-4 shifts for different modes. I don't work for the company, but the best $380 I ever spent.
Used the Diablo Predator 2 to disable the AFM system on my 2018 5.3L Silverado. Did the 87 tune as well with 3" cat back and getting 26mpg on the highway at around 70mph. Put around 3000 miles with the AFM turned off. Best mpg I did with the AFM on is 24mpg/87tune/3" cat back.
I don't mind the cylinder deactivation, but I do with they would give you the option to enable or disable it with a button. If there was an "Eco mode" button that does that, its fine. But there should also be another button for normal driving so it can run on all 8 cylinders.
If ur complaining about cylinder deactivation just wait till the 2019 Chevy‘s come out they all have stop/start technology I would much rather have half my cylinders turn off then my whole engine
You'll be able to turn it off. My wife's Mercedes has it but it only does it when several conditions are met. It's pretty ingenious actually. It has the option to turn it off anyways
yakitoriPB listen nobody cares about Mercedes because them shets only work for as long as the lease but Silverado are meant to be driven for 200k miles and this stop and start shet litterly destroys engines which is chevys game see they want you buy one every year and that’s why I left ford and Chevy and I now own a Nissan Titan xd cummins
Bobby Kuntz yea start stop is a whole other thing. 4 cyl mode is great. People don’t realize it’s not the 4cyl activation that makes these trucks slow. It’s the engine and transmission tune Chevy puts into the already sliggish revving LS engines. But stop start is fucking annoying.
@@yakitoriPB my girlfriends 2018 rubicon has it. We both hate it. You can turn it off, but you have to turn it off every time you restart the vehicle. It's a pain, and the engine winds up restarting all the time because the heat or ac stops running and it senses that the temp is changing too much so it restarts the engine anyway.
I just drive around in M5 and then don't switch into M6 until I'm on the highway running over 65mph. Never see "V4"...and no "Hocus Pocus" devices, disablers or anything else. I drove many miles from Wi to western South Dakota at 65MPH(on state roads) in 5th gear(roughly 2k RPM) and still averaged 22MPG. Most engines are designed to run most efficiently at between 1800 and 2k RPM so don't think for a minute you're hurting it running 2 or 2200 RPM for long periods. I run my boats V8 at 4k for long periods and never even think about it.
I hate the cylinder deactivation on my ram. It just can't keep up with the hilly Pennsylvania roads. Hesitation and vibration out the ass, I turn it off every time I drive.
I’m glad I found this site. My truck is doing same thing and consuming oil. Didn’t put the two together. I checked everything from tires, wheel bearings, drive shaft. Changed plugs and wires nothing worked. Getting to the point where I hate the truck. Going to give this a shot. I hope this works.
I bought it and it instantly fixed my truck. I drove it at all different speeds trying to make it run rough and couldn’t. This thing works. Truck is running smooth like never before. This has been driving me crazy for almost 2 years. I purchased straight from the website and it arrived in 3 days. With discount $189. 30 day money back guarantee. Well worth it. Thanks man
Blaise, I have a 5.3, 1500 and I use the Range disabler. I've also installed a catch-can. I couldn't see breaking in a new engine where half of the cylinders are not firing. How the heck are you going to set the rings properly? Anyway, happy with the Range. Also, a significant amount of oil is lost due to 0w/20 oil at 210 degrees being blown out the breather tube, into the valves where they (the valves) get gummed up. Just took an 800 mile trip, and emptied the catch-can before leaving. At the end of the trip, had about 2~3 ounces of oil in it.
@@RustyShackleford-me1iho you just empty the oil back into the engine, or replace it with new? Are they easy to install? Do they just plug in or bolt up? Any drilling etc?
I just bought one for my 2011 Sierra Texas Edition and i thought something was wrong with the truck before i knew what AFM was!!! So when i get the Range AFM Disabler i'll be happy!! Appreciate your video. Oh yeah....... YES $200 did hurt!
Just ordered one not worried about gas mileage tired of the jerking in the V4 to V8 mode and adding a quart and a half of oil between oil changes. Not to mention dont even feel like doing any engine work or replacement!
Just bought this getting It this week along with a new cold air intake a couple months after buying my borla atak system, trucks finally coming together
If you don’t want any lifter problems in the future your best bet is to do the d.o.d./ afm delete. It’s replaces the afm lifters with normal roller lifters. I did it to mine while I did the cam swap because those afm lifters would just break with the extra lift and pressure.
John Vesely is that 300 for parts and you did the work yourself, or? Already tried aftermarket valve cover , turns out was already done before I bought it, at 32k. Has 109k now and burning a little over 2 qts every 4k miles.
The gas mileage increases because it doesn't have to downshift nearly as much. When in 4 cylinder mode those 4 cylinders also have to move the weight of 4 deactivated cylinders, which requires more fuel. It's a V8 and it's supposed to be a V8. Not some 4 cylinder rice mobile
Best thing you have ever done. When it drops into v4 mode you are starving the other cylinders of oil. I just ended up having to fork out more than 10k for a new motor get rid of the v4 mode.
That's only good for city driving under 55mph. Highway driving you're gonna want the truck to up shift to 6th gear. I drive around town in M5 but once I jump on the highway the RPM's are soaring and the truck is begging for an upshift. And of course 6th gear in V4 the truck sounds horrendous with an aftermarket exhaust.
I put one in my 2018 Denali 6.2L and it's awesome. I think the 4-cylinder mode is a joke. I get 22-23 mpg going to my camp and its 140 miles one way. Cruise set at 75
So does it help the 8 speed transmission, or do you have issues with that as well? I’m just curious to see if that remedies it. It seems AFM would cause some affect to what people describe with the 8 speed.
I have a 2014 Silverado Z71 that I purchased new. Within 30,000 miles the thing started drinking nearly 2 quarts of oil between 4,500 mile oil changes. I found that astounding and disturbing as I have a 5.3 liter in my other truck with 160,000 miles that consumes no oil. My drive is along the Lake Huron shoreline for about 30 miles a day at 55 mph and that leaves the truck in 4 cylinder mode for nearly the whole trip. Since I purchased the Range Module my oil consumption has dropped to nearly nothing between oil changes. I would recommend this to anyone.
It shows up on your monthly diagnostic report that something is plugged into the ODB port . I started getting check engine light codes if I took it out and eventually suffered catalytic converters failures . Can’t say it was the module that did it . Ended up getting headers , high flow cats and a tune . Active fuel management is now turned off with my tune
Man , I'm glad I watched your video. I hate the 4cly - V8 mode switching . your 100% correct its a weird feeling almost like its missing. I'm definitely buying one for my 2015 silverado
I have 25,850 miles on my 2017 LT Z71 with the 4cyl mode active. I noticed no change in sound and I am averaging in and around town 19.4mpg. Now I live in a Foothills region of SC. The truck does do a lot of coasting and I have a K&N cold air induction system on the vehicle. I talked to a GM mechanic and he said switching from 8 to 4cyl does not change the oil consumption or wear characteristic of the engine. The mechanic no longer works for GM, he has his own shop, no real conflict of interest. I think the system name is ADEM (Active Dynamic Engine Management), it seems to work well. Now my wife has a 2019 Chevy Silverado LT Z71 purchased in December 2019 with the new engine management system. The engine varies cylinder use from 1 - 8 cylinders. With 2300 miles on her truck, with Hwy driving once a month, she averages about 22mpg. Wife's truck has no cold air induction system on it, just factory. P.S. she did not want me to put a cold air system on her new truck, the noise level is not to her taste. I will say this, the sound when the engine sucks more air with your foot in it only last for a few seconds, until the engine settles on a stable speed and RPM. So I can only speak from my experience, but the cylinder switching in our trucks do improve mpg. GM mechanic said the engine management systems varies which injectors are turned on and timing with cylinder variation. Lubrication and coolant systems continue to work as if all 8 cylinders are active. Engine Mpg also improves significantly when you are in cruise control. The real bottom line is we drive computers. :-)
I had one in my 17 Denali my MPG went down 1 MPG in the city that had the 6.2 in it, I just put one in my 2020 AT4 with the 5.3 the only problem with the newer trucks with the DFM is that it doesn't show from v4 to v8 mode because they are setup to run on 2,3,4,5,6,7,8 cylinders depending on how much power you need MPG city is 14 but truck is still in break in period
We just bought a 2020 Silverado, I will tell you this...I have gotten as much as 24 miles to the gallon on the highway with it going into v4. That's amazing for a 5.3 leader V8. I imagine milage will suffer if you disable the v4 function
I like the AFM (active fuel management). Its good when using cruise control. But you're right it does bug when in cruise mode and the exhaust does sound different.
ltllow1 I hate it. Makes the truck slow to respond and down shift when it wouldn’t otherwise need to on small hills and when spewing up a few mph on long stretches of road. And god forbid you have a strong headwind or hills on the interstate and the truck is constantly going from 4cyl mode to downshifting 2 gears and back into V8 mode constantly and speeding up and down excessively when using cruises.
My guy, who is a diesel mechanic (and his son who is a huge car guy) researched and as trucks get older the lubrication system is impacted as the switching causes wear in your system.. around the 104k Miles mark. Not taking any chances...
I have a 2016 Yukon SLT 5.3L and I have never felt it change from V4 to V8 mode, or from V8 to V4 mode. Maybe the ones "feeling it" are the ones who will have future problems. Per GM, the transfer is less than 20 milliseconds and is virtually imperceptible.
Ive been using AFM since 2012. On highway its gone up to 23mpg on stock wheels. Idk why I don't have a problem with it. I drive up to about 70-80 mph and then let it go to V4. I did do a complete AFM/DOD delete anyway because I replaced my cam for a performance one.
I got one of these for $60 and man what a difference for the way I drive. I can tell on idle to take off the delay is better or from a slow position to take off. I had to replace lifters twice in my Chevy pick-up so I sure wish I would have found these devices 5 years ago.
I use to hate the V4 mode and auto start stop but now I like it. I'm getting around 17-19mpg combined. My old 2004 Sierra only got 18s hwy and my Tundra got 16s hwy. On the freeway doing 70mph my Silverado can get between 21-22mpg. The V4 mode helps.
You feel it because it downshifts. The 2007-14s have a terrible AFM system, but for the 2015 redesign, they designed it where it switched between the two sets of 4. If im not thinking about it, i dont notice and have never had a problem.
I disabled mine because there is a flaw in the v4 mode.when the cylinders aren't firing oil goes by the valves causing oil consumption. Since installing no oil consumption at all.Plus why have a v8 that runs on 4 cylinders?
David McFarland there is a simple fix for that. I have a 14 Silverado, I check the oil twice between changes and use none. I have 85,000 miles. No problems at all..
This device is about $60 now. But same price to have PCM reprogramed. I spent $100 to deactivate AFM but included a performance upgrade and firming shifting through the TCM. Mpg has not changed.
I have a 2016 Chevy crew cab 1500 LTZ and I HATE my V4 mode in my truck. If I coast in V4 mode it will shake when I am going on a slight incline and I am going to try and buy this and hope for the best. Thank you for the video
I bought the hyper tech 8000 because it’s half the price of the range and it does both keep it in V8 mode and also it no longer shuts off at lights etc. I really didn’t mind the shutoff at lights thing because mine is E-assist and the starter does not crank over it just resumes running. But anyhow, The hyper tech 8000 works great .
I own a 2017 silverado 5.3 stock, my wife drives it to work every day 7 to 10 miles 2 times a day. She was shifting it into 5th gear to eliminate V-4 mode. We got the range ,we can now drive it normal in drive and we are getting better MPG. Like it! I wish GM gave us the choice.
In my 2018 1500 Silverado, you can't feel it when it changes to V4. It's great for cruise control on the highway, I've gotten 35mpg or so on flat stretches.
I’m pretty sure that DOD wasn’t just for Mpg it’s probably more for emissions to pass in any state/country. California is supposed to be really strict. I’d rather have all 8 myself...
I have an 07 new body style with a flowmaster super 10 and I absolutely HATE the AFM. When it switches over to v4 it sounds awful and sometimes you can feel it almost kick when it switches. There is little to no power when in v4 mode, and my gas mileage is all over the place, and I’ve heard it causes some wear on the engine so I’ll definitely be getting one eventually
I disabled mine after the engine light kept coming on due to bad oil pressure sensor going bad. Started with 16.4 miles to a gallon average. Been driving for about a year now and it gets 12.6 average. It doesn't change. I can live with that as long as I have all the power at the heals.
I just bought a used 15 Silverado with the 6.2 and somehow never noticed the shuddering stuff during the test drive, then got it home and noticed it right away. I thought great, I bought a lemon! Sounds like it's just a poor design though....think I'll give this little device a try and see if that fixes it. I love the truck but the shuddering crap is very annoying.
I got the device and my engine runs much smoother. Not sure about mileage yet. I have to get emissions test tomorrow and will let you know if I have any trouble
That shudder is so darn annoying. I've had to rebuild my transmission twice and I feel like it might be a cause in the wear. Had my 2014 Silverado ltz for a month and the transmission crapped on me. Fully rebuilt it and it shat on me a year later. Just had it recently rebuilt again last week. I swear if it goes out again before 10k miles I'm selling the darn thing.
All the serious issues for the GM 5.3 V8 are related/caused by the engine management system and the repairs can cost thousands. I have the Range Technology Modules on a 2014 GMC Sierra and a 2014 GMC Denali. Both vehicles now run as V8's should and no issues after 3 years with the Range product. Little or no difference in gas mileage and a small price to pay to avoid major engine issues. A system created to satisfy GM and the EPA, but a huge headache for vehicle owners.
My 2014 5.3 got 17 in the city and 20-21 on the highway with stock tires now after cold air intake and ko all terrain tires I’m averaging 13 in the city and 16 highway. I did step up to 265-70-18. Willing to try something to get better gas mileage.
GM did not iron it out, this unit is used to protect your engine, any performance increase is a bonus. They've had lifter (AFM/DFM lifters) failures in all 5.3 and 6.0 AFM/DFM truck engines from 2007 to 2021 with NO re-design. in 2022 they disabled it at the factory and in 2023 they got rid of it completely. If you have a lifter failure and catch it early you can replace the affected lifters ($2500 at dealer) and wait for it to happen again, if you let it go too long it will trash your cam and possibly your engine ($5-6000 at dealer). You can convert back to a standard non-AFM/DFM configuration with a cam/standard lifters/VLOM delete for big dollars after warranty at dealer/ private garage or install this device, remain in V8 mode for the life of your truck and avoid all of this mess.
I can’t wait for mine. The whole issue is when you jump on the throttle from rolling. Just my 2 cents, but it fails to activate v8 while decelerating. It downshifts properly, but if your still rolling and step on it the truck is in the correct gear the motor just isn’t giving it the juice and causes that shudder, I hate it. Like taking off in a stick shift without enough throttle!
I watch my 2018 on the highway and sometimes it’s better in v8 than v4. Thats this winter and last summer/ fall it was doing good in warm weather. Did you get this on amazon?
I bought mine directly from range tech. my truck is a 2018 Silverado LTZ Midnight Edition with 5.3 Liter in it. do not by on any other website cause you may end up getting an older unit that does have the upgraded OS system in it... buy direct from range tech its the safest bet.
I just bought a 2014 Silverado 1500 with 130k and it still has the AFM. so far nothing is wrong with the engine but I feel as if it might be too late to do anything now. Whatever internal damage has already been done
I'm going a bit off topic with a different annoyance on today's cars and trucks. A few months ago I rented a Chevy Malibu while my Elantra was in the body shop. I believe it had the Ecotech Four. This was my first experience with auto stop/start. The car was nice, and mostly served me well. But that stop/start was annoying. Every time I stopped, the engine shut down. And I'd feel it fire back up when I tapped the gas. I can't imagine this is good for an engine in the long-term. And you can't turn off the function in this model. 😞
Holy crap 20 mpg !! /kinda highway miles no stopping going. City driving be a good assessment after current . But wow still neat and well worth every penny!!! Swell investment!!
First thing I did with my 2o14 Silverado was have it reprogrammed with afm disabled. 70k mikes and it runs great. That cylinder deactivation by gm is the dumbest thing ever. I think I lost 1 mpg. It was so clunky and made the truck run like shit. It will void you’re warranty doesn’t make sure you have a dealer do it so you can have them default it if something happens. They know it sucks as well.
I have never had an issue with my 2015 Silverado. On the highway averaging over 70 mph I get over 20 mpg. My record was when it was new going on a certain route that must have been perfect conditions I got 29mpg. I was going 55 the whole way just to see what I could get. I still have 28.8 showing as my highest (same route), it cleared the 29 when the dealer had to disconnect the battery for something they were doing. But I've always kind of liked it as far as mileage goes and it never bothered me. If mine acted like yours maybe it would though. Just seems like yours isn't running right for some reason. Try talking to a GM master mechanic and see what he says.
I have heard a lot of issues on these trucks with lifter problems because of this. I absolutely hate it on my All Terrain. I have noticed zero difference in MPG in the 2k miles I've put on mine on it going from V4 to V8. Driving mine through town really irritates me from the fact of the truck doesn't act like it knows what it wants to do, makes the truck feel shitty from how bad it can clunk, lol. Glad to see this worked for you; I'll be ordering mine soon. Does the light stay on while the truck is off?
My lifters tick and make all sorts of sound, and it sounds like shit in v4 mode, and I hate it, it clunks and I don’t see a difference in mileage, and I’ve got some weird oil pressure problem that comes and goes and I honestly think this caused it, I’m probably gonna get one of my these
My buddies lifters got stuck open at 42k miles on a 2014 z71 1500 and had to have both sides replaced.. My dad and I were shocked lol.. that explains it though!
One of my lifters in my 2008 went out after about 190,000 miles of this so we replaced the lifter and disabled the v4 mode and haven't any problems since
Yeah I understand what you're saying like soon as you give it a little bit of gas goes right to V8 right away like you should be able to run on four cylinder or six cylinder or eight cylinder like Dodge you know or just four and eight and then use the motor when you want to right so this way it gives it more power cuz that's where it does it helps you save power when you're using the motor I don't know if there is a hybrid or not so four cylinder and put in that hybrid on would be awesome you save a lot of fuel but if you're carrying the heavy load it'd be great to switch it to V8 and put it on the hybrid mode
Great Video. When I see folks drive these new trucks I often wonder what they do for a living to afford them. Since I can't, I'll live vicariously ;) I drive a 95 K1500 but am curious how the new ones are. It looks pretty cool and the gas mileage looks great. I was curious/jealous about the 4 cyl mode but now I understand it much better. Thanks for the video.
My 08 Z71 has a new crate motor with 3,000 miles, 33x12.50 tires and I get 14.5mpg if I'm lucky with the AFM working. I'm gonna try this thing and see if it improves, and I don't wanna possibly cause premature wear in the cylinders.
Raul Cantu I had that issue with my ‘14 Silverado 1500. Then it got worse and started reading anti theft warning and wouldn’t start. I found this video and read more about it. Figured I would try it and see. My grounds weren’t that bad but I cleaned both of them under the dash pad and added dielectric grease and haven’t had any issues in 6 months. th-cam.com/video/Ab-OF3WtpRQ/w-d-xo.html
Heres a 1 year review of the range! - th-cam.com/video/7mmxCaCYNjo/w-d-xo.html
Thanks for the video, I am from the Netherlands in Europe and I want to know if it's works for the C7 chevrolet corvette thanks
Fuel mileage still doing better?
Being 3 years or so later. How is this device holding up ? Causing any engine problems anything ?
The simple answer is they should have included the ability to deactivate it from the factory.
Make That Point Actually GM did it to compete against the ecoboost. Has nothing to do with Obama. If that was the case, then Ram would have included it in the Hemi and Ford in the Coyote.
Make That Point hemis do have a version of this called multi displacement. It’s more advanced in my opinion and it doesn’t affect performance as much as v4 does
@@skully720 No they didn't. Nobody knew about the Ecoboost until 2009-2010, this engine came out in 2006. Besides, this is not a way to compete with a twin-turbo charged V6.
Dodge too
Carlos Salinas they did dodge has 4cylinder mode for 4 years now
This is the best 150.00 fix for a problem that GM caused more problems than a solution to fuel mileage! Good video! keep your V8 a true V8!!
Bought one for my 07 Avalanche works great.I would recommend this product.Truck started using oil 2 quarts a month from blow back into unfiring pistons in V4. No oil consumption now.
Can u send me part number
I have my 07 avalanche on sell right now does this really work n is their one you would recommend I'm getting the p300 error code
We had a new 2011 silverado 1500 burning oil like crazy because of the v4 mode. Got this same model of obd2 accessory, and 150k miles later, we haven't burned any oil and the truck feels better to drive. Definitely a good investment!
I use one of these on my 5.3 Silverado , slightly better mpg , no more oil consumption between oil changes and the truck sounds and runs great .
Michael Proulx is it still running great ?
Better mpg?
I have one on my truck and it's a must if you're doing exhaust to keep it from droning.
Update : I traded my 2010 Silverado LTZ 5.3, for a 2015 Silverado LTZ 6.2 and brought my range technology disabler over to the new truck. It worked great on my 10, my gas mileage seemed to improve slightly, and oil consumption stopped.
The 15, the mileage went down a small amount, oil consumption either slowed down dramatically or stopped.
I tested it for 3 weeks with and 3 weeks without. I drive about 100 miles a day 70% are highway miles the rest city driving.
Just like the 10, it works great, the engine seems happier, in my mind as a life long drag racer, I don't like the idea of 4 dead pistons and rods putting unnecessary drag on the rest of the engine. I get the concept but if I wanted a 4 cylinder that's what I would have bought. As for the 6.2, I love it, it's a beast, she runs great and sounds good too.
Either of the new 2014 I had and now the 2018 use no oil,,
I have 2016 Silverado 5.3 bought Range it works great to keep in v8 mode. I use a pedal commander. The truck has dual exhaust with cats and third cat removed, then each cat piped into one cherrybomb extreme muffler 2in 2out. Pipes run out behind rear wheels. Engine is using cold air intake kn filter.Truck has great sound and power for slightly modded truck. I do however one day a month take range out just for gp. Have no oil loss using a McNally oil seporater 3 line. The range is great. Hey Man great video.
.
Worth every cent. I just recently got one for my 2014 Sierra. No more lag when trying to step on the gas during city cruising. The power is always there now. It feels entirely like a different vehicle in town. Also, no more annoying chirp from the muffler flapper.
Is that what that noise is when I get on the gas?
Where you bought it? Thanks
@@hexrah2669 yes, mine does it. Most annoying damn thing
Wait mine does that too ! Haha I can’t believe I finally stumbled upon a solution
Not only is it annoying. It also causes lifters to lock down and the possibly wipe the cam. These lifters can only be replaced after removing the heads. Then,if the cam is bad,you have to remove engine mounts so you can lift the engine to remove the oil pan. That's the only way,short of pulling your engine,to get the oil pump from around your crank. A big job.
I have a $0 fix for this called an ABFI. Always Be Flooring It!
Always!!!!!
thatll cost you at the pump way more than just paying for the device 🤣
I have a $0 fix for this. It's called walking. I'd rather walk than buy any GM car with cylinder deactivation.
Hahaha lol
The people at Valvoline told me I had a “severe” oil leak on my 09 Tahoe LTZ. Turns out, I just needed this! Thanks for sharing.
Wait what? Please go into detail
Fr
I had a 2015 Suburban run almost flawlessly from July 4, 2015 (new) through August 4, 2023 when it was totalled in a rearend accident. The cyclinder deactivation was flawless. It had no shakes or sounds and worked to get great milage.
I like to see the test using the cruise control on the same road with the fuel tank full. Then check the gas mileage
Yep, you are correct, the damn vehicle jiggles when it changes to and from. I hate the v4 mode
The V4 mode is good for deceleration and it should be used for idle too but it’s little to be desired.
@@dam4274 worst idea ever. Does not make sense lol
@@darkhelmet4279 Our Yukon does it at t9mes.
Do you hear it?
Here is how you DO IT FOR FREE!!!
For anybody who doesn’t know you can run these trucks in Manual mode but put it one gear down from the highest gear (5th gear for me, since I have a 6spd) and leave it there when you’re not on the interstate and don’t need the overdrive, and it’ll still act like the normal automatic and stay in V8 mode 100%. And you can shift between Drive and Manual mode in these trucks on the fly with no harm.
oh really?
Yes. My question is do you have to do anything different or just plug it back in. If you need the computer port. I like my truck as quiet as possible. My 2017 Silverado is working fine so far 26000 avg around 17 + mpg . Should I do this or not?
Just got Range AFM disabler. . I have a 2018 Sierra All Terrain 5.3 8 speed transmission. . Everything stock so far. I have ran two tanks and have not seen any noticeable difference on fuel economy. I have seen better throttle response. It eliminated the intermittent strange jerks the tranny did particular at lower speeds. I spoke with the service manager at my local GM dealer and he said warranty will not be affected. He was curious and wanted me to report on the performance results after about a months use.
I'm glad you commented, seems like a lot of people don't want to believe what i and you said.
I cant wait to try one of these but also FYI not all of the jerking and shuddering is due to this. There is a Torque Converter issue with all of these trucks. GM knows about it but the service guys always try to blow it off. I found the service bulletin from GM and took it in to be serviced and now they are replacing it. When you are informed there is not much they can do or say. EVERYONE should know about these TCC issues, i know we all have felt the shudder like your driving on rumble strips when you go from a coast to tipping back in the throttle.
@@jeremiahbrown4437 do you have the tsb#? I think my torque converter is going out and they keep telling me normal.
Douglas Hill #PIP5504A is what is at the top of the document I have.
Jeremiah Brown is that just for V8 trucks? My dad's 4.3 '14 Silverado has that issue.
Cool...yeh, that DoD (4 cylinder mode deal) really upsetted me for years on my 2014 Chevy Silverado 4x4 (5.3L). Finally bought a canned tuner (Diablo i3 inTune) performance tuner module. I was able to disable that DoD, disable the speed limiter, increase throttle response 10%, recalibrate for taller tires, and do their canned "Flex 91 octane" tune. Everything I did was readily apparent (the module "does what it says"). Amazing how the truck runs now. Smoother, better throttle response, better acceleration, and it holds the shifts longer (like a truck should). I was also able to "tweak" the 1-2, 2-3, and 3-4 shifts for different modes. I don't work for the company, but the best $380 I ever spent.
Have you not heard how the truck sounds when it goes into v4 mode? With an aftermarket exhaust, it goes into a deeeeeep rumble. Very nice sound.
i got the borla Atak and its louder in v4. can confirm you can definitely tell when it enters v4.
Used the Diablo Predator 2 to disable the AFM system on my 2018 5.3L Silverado. Did the 87 tune as well with 3" cat back and getting 26mpg on the highway at around 70mph. Put around 3000 miles with the AFM turned off. Best mpg I did with the AFM on is 24mpg/87tune/3" cat back.
How can you off AMF of Z71?
What's the 87 tune?
I don't mind the cylinder deactivation, but I do with they would give you the option to enable or disable it with a button. If there was an "Eco mode" button that does that, its fine. But there should also be another button for normal driving so it can run on all 8 cylinders.
You don't mind it..... Yet lol
If not on the highway... Or going over 55 mph... Just pull it down in m and bump it up to 5..
If ur complaining about cylinder deactivation just wait till the 2019 Chevy‘s come out they all have stop/start technology I would much rather have half my cylinders turn off then my whole engine
Bobby Kuntz not only that, it can shut down to just one cylinder lol. Problems galore.
You'll be able to turn it off. My wife's Mercedes has it but it only does it when several conditions are met. It's pretty ingenious actually. It has the option to turn it off anyways
yakitoriPB listen nobody cares about Mercedes because them shets only work for as long as the lease but Silverado are meant to be driven for 200k miles and this stop and start shet litterly destroys engines which is chevys game see they want you buy one every year and that’s why I left ford and Chevy and I now own a Nissan Titan xd cummins
Bobby Kuntz yea start stop is a whole other thing. 4 cyl mode is great. People don’t realize it’s not the 4cyl activation that makes these trucks slow. It’s the engine and transmission tune Chevy puts into the already sliggish revving LS engines.
But stop start is fucking annoying.
@@yakitoriPB my girlfriends 2018 rubicon has it. We both hate it. You can turn it off, but you have to turn it off every time you restart the vehicle. It's a pain, and the engine winds up restarting all the time because the heat or ac stops running and it senses that the temp is changing too much so it restarts the engine anyway.
AFM: Proudly killing engines and requiring rebuilds since 2007.
I was going. Get.one.why how does.it destroy engine
After complete delete runs like new.
Well it killed my 13 Yukon! Fuckin blows
@@myquickjab2098 because eventually you can get lifter collapse
got an 08 1500 5.3l with AFM 200K miles doesn't leak a drop of oil and runs like a top, i guess i got lucky.
I just drive around in M5 and then don't switch into M6 until I'm on the highway running over 65mph. Never see "V4"...and no "Hocus Pocus" devices, disablers or anything else. I drove many miles from Wi to western South Dakota at 65MPH(on state roads) in 5th gear(roughly 2k RPM) and still averaged 22MPG. Most engines are designed to run most efficiently at between 1800 and 2k RPM so don't think for a minute you're hurting it running 2 or 2200 RPM for long periods. I run my boats V8 at 4k for long periods and never even think about it.
I hate the cylinder deactivation on my ram. It just can't keep up with the hilly Pennsylvania roads. Hesitation and vibration out the ass, I turn it off every time I drive.

I’m glad I found this site. My truck is doing same thing and consuming oil. Didn’t put the two together. I checked everything from tires, wheel bearings, drive shaft. Changed plugs and wires nothing worked. Getting to the point where I hate the truck. Going to give this a shot. I hope this works.
I hate to say but if its already burning oil this probably will not help it. However it is worth a shot.
I bought it and it instantly fixed my truck. I drove it at all different speeds trying to make it run rough and couldn’t. This thing works. Truck is running smooth like never before. This has been driving me crazy for almost 2 years. I purchased straight from the website and it arrived in 3 days. With discount $189. 30 day money back guarantee. Well worth it. Thanks man
Blaise,
I have a 5.3, 1500 and I use the Range disabler. I've also installed a catch-can. I couldn't see breaking in a new engine where half of the cylinders are not firing. How the heck are you going to set the rings properly?
Anyway, happy with the Range. Also, a significant amount of oil is lost due to 0w/20 oil at 210 degrees being blown out the breather tube, into the valves where they (the valves) get gummed up. Just took an 800 mile trip, and emptied the catch-can before leaving. At the end of the trip, had about 2~3 ounces of oil in it.
@@RustyShackleford-me1iho you just empty the oil back into the engine, or replace it with new? Are they easy to install? Do they just plug in or bolt up? Any drilling etc?
I just bought one for my 2011 Sierra Texas Edition and i thought something was wrong with the truck before i knew what AFM was!!! So when i get the Range AFM Disabler i'll be happy!! Appreciate your video. Oh yeah....... YES $200 did hurt!
Just ordered one not worried about gas mileage tired of the jerking in the V4 to V8 mode and adding a quart and a half of oil between oil changes. Not to mention dont even feel like doing any engine work or replacement!
Just bought this getting It this week along with a new cold air intake a couple months after buying my borla atak system, trucks finally coming together
If you don’t want any lifter problems in the future your best bet is to do the d.o.d./ afm delete. It’s replaces the afm lifters with normal roller lifters. I did it to mine while I did the cam swap because those afm lifters would just break with the extra lift and pressure.
John Vesely how much did you spend to do the delete?
Brandon Colameco I want to say it was around $300, I think it was more because I replaced all my lifters with new ones.
John Vesely is that 300 for parts and you did the work yourself, or? Already tried aftermarket valve cover , turns out was already done before I bought it, at 32k. Has 109k now and burning a little over 2 qts every 4k miles.
Brandon Colameco 300 for parts, we did it ourselves you just have to remove the heads to get the lifters out
The gas mileage increases because it doesn't have to downshift nearly as much. When in 4 cylinder mode those 4 cylinders also have to move the weight of 4 deactivated cylinders, which requires more fuel. It's a V8 and it's supposed to be a V8. Not some 4 cylinder rice mobile
Best investment you’ll ever make in your truck.If that device proves to be reliable over the years, it’s worth every penny.
Best thing you have ever done. When it drops into v4 mode you are starving the other cylinders of oil. I just ended up having to fork out more than 10k for a new motor get rid of the v4 mode.
You can also shift the shifter down to manual and manually go up to 5 gear and it won’t let it go into overdrive.
Or put the truck in manual shift mode and put it in 5th gear and it’ll never go into V4 mode. And it’s free
and annoying to have to do that lol 200 is well worth to me not having to deal with running a gear high or it jumping in and out of v4 mode.
That's only good for city driving under 55mph. Highway driving you're gonna want the truck to up shift to 6th gear. I drive around town in M5 but once I jump on the highway the RPM's are soaring and the truck is begging for an upshift. And of course 6th gear in V4 the truck sounds horrendous with an aftermarket exhaust.
TwoWheelinInc nailed it
disabled afm with diablo tuner and no more issues or oil consumption
lmfscrew I have a question would it be better just to buy a tuner other than this ? It cost as much as a tuner just curious
I put one in my 2018 Denali 6.2L and it's awesome. I think the 4-cylinder mode is a joke. I get 22-23 mpg going to my camp and its 140 miles one way. Cruise set at 75
So does it help the 8 speed transmission, or do you have issues with that as well? I’m just curious to see if that remedies it. It seems AFM would cause some affect to what people describe with the 8 speed.
I have a 2014 Silverado Z71 that I purchased new. Within 30,000 miles the thing started drinking nearly 2 quarts of oil between 4,500 mile oil changes. I found that astounding and disturbing as I have a 5.3 liter in my other truck with 160,000 miles that consumes no oil. My drive is along the Lake Huron shoreline for about 30 miles a day at 55 mph and that leaves the truck in 4 cylinder mode for nearly the whole trip. Since I purchased the Range Module my oil consumption has dropped to nearly nothing between oil changes. I would recommend this to anyone.
It shows up on your monthly diagnostic report that something is plugged into the ODB port . I started getting check engine light codes if I took it out and eventually suffered catalytic converters failures . Can’t say it was the module that did it . Ended up getting headers , high flow cats and a tune . Active fuel management is now turned off with my tune
Man , I'm glad I watched your video. I hate the 4cly - V8 mode switching . your 100% correct its a weird feeling almost like its missing. I'm definitely buying one for my 2015 silverado
What do I need to fix a silverado 5.3 2011 staying in 4 clinder
Name of that device and where to get it please
I have 25,850 miles on my 2017 LT Z71 with the 4cyl mode active. I noticed no change in sound and I am averaging in and around town 19.4mpg. Now I live in a Foothills region of SC. The truck does do a lot of coasting and I have a K&N cold air induction system on the vehicle. I talked to a GM mechanic and he said switching from 8 to 4cyl does not change the oil consumption or wear characteristic of the engine. The mechanic no longer works for GM, he has his own shop, no real conflict of interest. I think the system name is ADEM (Active Dynamic Engine Management), it seems to work well. Now my wife has a 2019 Chevy Silverado LT Z71 purchased in December 2019 with the new engine management system. The engine varies cylinder use from 1 - 8 cylinders. With 2300 miles on her truck, with Hwy driving once a month, she averages about 22mpg. Wife's truck has no cold air induction system on it, just factory. P.S. she did not want me to put a cold air system on her new truck, the noise level is not to her taste. I will say this, the sound when the engine sucks more air with your foot in it only last for a few seconds, until the engine settles on a stable speed and RPM.
So I can only speak from my experience, but the cylinder switching in our trucks do improve mpg. GM mechanic said the engine management systems varies which injectors are turned on and timing with cylinder variation. Lubrication and coolant systems continue to work as if all 8 cylinders are active. Engine Mpg also improves significantly when you are in cruise control. The real bottom line is we drive computers. :-)
I pull my boat from Jax fl to the Keys once a year. The V4 mode helps out on fuel economy.
I just got mine in my 2016 gmc z71 and what a major difference, I highly recommend, no more v4 anymore!!!!
I had one in my 17 Denali my MPG went down 1 MPG in the city that had the 6.2 in it, I just put one in my 2020 AT4 with the 5.3 the only problem with the newer trucks with the DFM is that it doesn't show from v4 to v8 mode because they are setup to run on 2,3,4,5,6,7,8 cylinders depending on how much power you need MPG city is 14 but truck is still in break in period
What do you get for highway? I have a 14 Denali. Going 60mph with my 6.2 I'm getting 25mpg
@@thentantt the best I got with my Denali at 70 mph on cruise was 22.5 mpg, my AT4 which has 3000 miles on it now the best so far is 19.5 mpg
We just bought a 2020 Silverado, I will tell you this...I have gotten as much as 24 miles to the gallon on the highway with it going into v4. That's amazing for a 5.3 leader V8. I imagine milage will suffer if you disable the v4 function
How did you delete it on yours? I have a 2020 also
I like the AFM (active fuel management). Its good when using cruise control. But you're right it does bug when in cruise mode and the exhaust does sound different.
ltllow1 I hate it. Makes the truck slow to respond and down shift when it wouldn’t otherwise need to on small hills and when spewing up a few mph on long stretches of road. And god forbid you have a strong headwind or hills on the interstate and the truck is constantly going from 4cyl mode to downshifting 2 gears and back into V8 mode constantly and speeding up and down excessively when using cruises.
@@chevyon37s your right. I bought the piece that plugs in the obd2. Its now more responsive. Much better.
My guy, who is a diesel mechanic (and his son who is a huge car guy) researched and as trucks get older the lubrication system is impacted as the switching causes wear in your system.. around the 104k Miles mark. Not taking any chances...
You won’t like it if you loose a lifter or two
I have a 2016 Yukon SLT 5.3L and I have never felt it change from V4 to V8 mode, or from V8 to V4 mode. Maybe the ones "feeling it" are the ones who will have future problems. Per GM, the transfer is less than 20 milliseconds and is virtually imperceptible.
Great info , thanks.
Have an 09 GMC im considering converting, hope it works!
Ive been using AFM since 2012. On highway its gone up to 23mpg on stock wheels. Idk why I don't have a problem with it. I drive up to about 70-80 mph and then let it go to V4. I did do a complete AFM/DOD delete anyway because I replaced my cam for a performance one.
How often have u had to replace lifters?
@@prisonmike7868 never.
The jumping rpm drives me nuts. It can cause on jerks going from coasting to hard throttle and the drone from the exhaust is trash
Same here! Disabled the V4 mode and now I'm hitting 10+ MPG more than before
No way you are getting 10+ mpg better 😂
I got one of these for $60 and man what a difference for the way I drive. I can tell on idle to take off the delay is better or from a slow position to take off. I had to replace lifters twice in my Chevy pick-up so I sure wish I would have found these devices 5 years ago.
I use to hate the V4 mode and auto start stop but now I like it. I'm getting around 17-19mpg combined. My old 2004 Sierra only got 18s hwy and my Tundra got 16s hwy. On the freeway doing 70mph my Silverado can get between 21-22mpg. The V4 mode helps.
You feel it because it downshifts. The 2007-14s have a terrible AFM system, but for the 2015 redesign, they designed it where it switched between the two sets of 4. If im not thinking about it, i dont notice and have never had a problem.
I just came from a video that showed what happens when a lifter collapses. 200$ is a bargain!
I installed this same one on my 2007 Tahoe LTZ 4x4 and it stays in V-8 mode always. Works as designed! A+
Are u fr
@@jesse9354 fr?
FloridaCoastalGuy I know this is late, but fr = for real
@@rizwanwali4223 THANKS!
I don't get why all you guys want to disable v4 mode. I usually average 23.2 mpg at 76 MPH with the AC on. Use the truck as it was designed for.
PhillLsx Ga. they don’t wanna save gas
I disabled mine because there is a flaw in the v4 mode.when the cylinders aren't firing oil goes by the valves causing oil consumption. Since installing no oil consumption at all.Plus why have a v8 that runs on 4 cylinders?
David McFarland there is a simple fix for that. I have a 14 Silverado, I check the oil twice between changes and use none. I have 85,000 miles. No problems at all..
@@philllsxga.7737 what's the fix then?
David McFarland there are some TH-cam videos about the pcv being in the wrong spot. What year is yours?
This device is about $60 now. But same price to have PCM reprogramed. I spent $100 to deactivate AFM but included a performance upgrade and firming shifting through the TCM. Mpg has not changed.
Where have u found it for $60?
The comments are amazing 👏 🤣 it made me few minutes late for my chiropractor appointment
I have a 2016 Chevy crew cab 1500 LTZ and I HATE my V4 mode in my truck. If I coast in V4 mode it will shake when I am going on a slight incline and I am going to try and buy this and hope for the best. Thank you for the video
Mine chirps everytime it switches
I've got a 2017 GMC Denali bought this range module years ago money well spent.
We’re I can I buy one of these adapters?
I put mine in low gear and toggle up to fifth gear, always in v 8 mode. Went 400 miles over the Sierra Nevada and got 22.7 miles to the gallon.
I bought the hyper tech 8000 because it’s half the price of the range and it does both keep it in V8 mode and also it no longer shuts off at lights etc. I really didn’t mind the shutoff at lights thing because mine is E-assist and the starter does not crank over it just resumes running. But anyhow, The hyper tech 8000 works great .
I own a 2017 silverado 5.3 stock, my wife drives it to work every day 7 to 10 miles 2 times a day. She was shifting it into 5th gear to eliminate V-4 mode. We got the range ,we can now drive it normal in drive and we are getting better MPG. Like it! I wish GM gave us the choice.
In my 2018 1500 Silverado, you can't feel it when it changes to V4. It's great for cruise control on the highway, I've gotten 35mpg or so on flat stretches.
Same hear but idid get a little transmission slip when engine was cold in 2nd gear
Car guys can feel it
haven't taken my 2014 5.3L for a trip yet but 35 MPG sounds good af!
If your driving around town put in manual 5 and it won’t go to v4 trust me it help when you have flowmasters. Plus I think you get better mpg
Yea but thats something your constantly having to do and at the end of the day its going to hop in and out of v4 as soon as you hit the highway.
I have mine on m5 at all times until I hit the highway… i then press up put it on m6, no v4 bs at all
So many devices to plug into the obd location these days you need four of them.
I’m pretty sure that DOD wasn’t just for Mpg it’s probably more for emissions to pass in any state/country. California is supposed to be really strict. I’d rather have all 8 myself...
I have an 07 new body style with a flowmaster super 10 and I absolutely HATE the AFM. When it switches over to v4 it sounds awful and sometimes you can feel it almost kick when it switches. There is little to no power when in v4 mode, and my gas mileage is all over the place, and I’ve heard it causes some wear on the engine so I’ll definitely be getting one eventually
Yea i hated how the trans felt when it went to v4. Felt almost like it was slipping. Not anymore though, feels great.
Might have to check one of these out.
I disabled mine after the engine light kept coming on due to bad oil pressure sensor going bad. Started with 16.4 miles to a gallon average. Been driving for about a year now and it gets 12.6 average. It doesn't change. I can live with that as long as I have all the power at the heals.
I just bought a used 15 Silverado with the 6.2 and somehow never noticed the shuddering stuff during the test drive, then got it home and noticed it right away. I thought great, I bought a lemon! Sounds like it's just a poor design though....think I'll give this little device a try and see if that fixes it. I love the truck but the shuddering crap is very annoying.
Have a 2018 and get well over 20MPG on high way. Like 25.6 MPG I use 4/8 cyl mode.
Bill14886 with the wind up your back side. Never in normal driving.
I notice your coolant temp also goes above 210 ...mine 2018 does too
I got the device and my engine runs much smoother. Not sure about mileage yet. I have to get emissions test tomorrow and will let you know if I have any trouble
passed emissions with flying colors
Or you could use M5
Just get a performance hand held tuner you can deactivate it too and tune your truck and do more tuning
That shudder is so darn annoying. I've had to rebuild my transmission twice and I feel like it might be a cause in the wear. Had my 2014 Silverado ltz for a month and the transmission crapped on me. Fully rebuilt it and it shat on me a year later. Just had it recently rebuilt again last week. I swear if it goes out again before 10k miles I'm selling the darn thing.
All the serious issues for the GM 5.3 V8 are related/caused by the engine management system and the repairs can cost thousands.
I have the Range Technology Modules on a 2014 GMC Sierra and a 2014 GMC Denali. Both vehicles now run as V8's should and no issues after 3 years with the Range product. Little or no difference in gas mileage and a small price to pay to avoid major engine issues. A system created to satisfy GM and the EPA, but a huge headache for vehicle owners.
My 2014 5.3 got 17 in the city and 20-21 on the highway with stock tires now after cold air intake and ko all terrain tires I’m averaging 13 in the city and 16 highway. I did step up to 265-70-18. Willing to try something to get better gas mileage.
robbiehayes569 those are 10 ply tires. You’re not going to get good gas mileage.
GM did not iron it out, this unit is used to protect your engine, any performance increase is a bonus. They've had lifter (AFM/DFM lifters) failures in all 5.3 and 6.0 AFM/DFM truck engines from 2007 to 2021 with NO re-design. in 2022 they disabled it at the factory and in 2023 they got rid of it completely. If you have a lifter failure and catch it early you can replace the affected lifters ($2500 at dealer) and wait for it to happen again, if you let it go too long it will trash your cam and possibly your engine ($5-6000 at dealer). You can convert back to a standard non-AFM/DFM configuration with a cam/standard lifters/VLOM delete for big dollars after warranty at dealer/ private garage or install this device, remain in V8 mode for the life of your truck and avoid all of this mess.
I can’t wait for mine. The whole issue is when you jump on the throttle from rolling. Just my 2 cents, but it fails to activate v8 while decelerating. It downshifts properly, but if your still rolling and step on it the truck is in the correct gear the motor just isn’t giving it the juice and causes that shudder, I hate it. Like taking off in a stick shift without enough throttle!
I watch my 2018 on the highway and sometimes it’s better in v8 than v4. Thats this winter and last summer/ fall it was doing good in warm weather. Did you get this on amazon?
I bought mine directly from range tech. my truck is a 2018 Silverado LTZ Midnight Edition with 5.3 Liter in it. do not by on any other website cause you may end up getting an older unit that does have the upgraded OS system in it... buy direct from range tech its the safest bet.
I just bought a 2014 Silverado 1500 with 130k and it still has the AFM. so far nothing is wrong with the engine but I feel as if it might be too late to do anything now. Whatever internal damage has already been done
At today's fuel prices I'm not worried about miles per gallon , it's more like smiles per gallon! I'm going to enjoy hammering that throttle!
I'm going a bit off topic with a different annoyance on today's cars and trucks. A few months ago I rented a Chevy Malibu while my Elantra was in the body shop. I believe it had the Ecotech Four. This was my first experience with auto stop/start. The car was nice, and mostly served me well. But that stop/start was annoying. Every time I stopped, the engine shut down. And I'd feel it fire back up when I tapped the gas. I can't imagine this is good for an engine in the long-term. And you can't turn off the function in this model. 😞
8:43 you're welcome.
You are a god!
Gyat damn. Thank you. This dude just rambling his ass off.
TY... And you should change your profile name to every minute counts 😂
Holy crap 20 mpg !! /kinda highway miles no stopping going. City driving be a good assessment after current . But wow still neat and well worth every penny!!! Swell investment!!
First thing I did with my 2o14 Silverado was have it reprogrammed with afm disabled.
70k mikes and it runs great. That cylinder deactivation by gm is the dumbest thing ever. I think I lost 1 mpg. It was so clunky and made the truck run like shit. It will void you’re warranty doesn’t make sure you have a dealer do it so you can have them default it if something happens. They know it sucks as well.
I have never had an issue with my 2015 Silverado. On the highway averaging over 70 mph I get over 20 mpg. My record was when it was new going on a certain route that must have been perfect conditions I got 29mpg. I was going 55 the whole way just to see what I could get. I still have 28.8 showing as my highest (same route), it cleared the 29 when the dealer had to disconnect the battery for something they were doing. But I've always kind of liked it as far as mileage goes and it never bothered me. If mine acted like yours maybe it would though. Just seems like yours isn't running right for some reason. Try talking to a GM master mechanic and see what he says.
My highest is 28 mpg as well. I have a 2016 chevy tahoe...
I have heard a lot of issues on these trucks with lifter problems because of this. I absolutely hate it on my All Terrain. I have noticed zero difference in MPG in the 2k miles I've put on mine on it going from V4 to V8. Driving mine through town really irritates me from the fact of the truck doesn't act like it knows what it wants to do, makes the truck feel shitty from how bad it can clunk, lol. Glad to see this worked for you; I'll be ordering mine soon. Does the light stay on while the truck is off?
Nope light goes off. Its definitely worth it!
My lifters tick and make all sorts of sound, and it sounds like shit in v4 mode, and I hate it, it clunks and I don’t see a difference in mileage, and I’ve got some weird oil pressure problem that comes and goes and I honestly think this caused it, I’m probably gonna get one of my these
My buddies lifters got stuck open at 42k miles on a 2014 z71 1500 and had to have both sides replaced.. My dad and I were shocked lol.. that explains it though!
One of my lifters in my 2008 went out after about 190,000 miles of this so we replaced the lifter and disabled the v4 mode and haven't any problems since
Brighton Collver are you talking about the V4 mode or the Range AFM deactivation device?
Yeah I understand what you're saying like soon as you give it a little bit of gas goes right to V8 right away like you should be able to run on four cylinder or six cylinder or eight cylinder like Dodge you know or just four and eight and then use the motor when you want to right so this way it gives it more power cuz that's where it does it helps you save power when you're using the motor I don't know if there is a hybrid or not so four cylinder and put in that hybrid on would be awesome you save a lot of fuel but if you're carrying the heavy load it'd be great to switch it to V8 and put it on the hybrid mode
Great Video. When I see folks drive these new trucks I often wonder what they do for a living to afford them. Since I can't, I'll live vicariously ;) I drive a 95 K1500 but am curious how the new ones are. It looks pretty cool and the gas mileage looks great. I was curious/jealous about the 4 cyl mode but now I understand it much better. Thanks for the video.
Build that credit and make payments
Disabling the 4 cylinder deactivation sucks more gas doesn’t it? Why would u do that?
My 08 Z71 has a new crate motor with 3,000 miles, 33x12.50 tires and I get 14.5mpg if I'm lucky with the AFM working. I'm gonna try this thing and see if it improves, and I don't wanna possibly cause premature wear in the cylinders.
I watched this video yesterday and realized I was able to deactivate the active fuel management with my Edge G2 programmer.
william rizzo what year is your truck ?
Should I buy one that’s $60 or $220 because the $60 one will work with mine
And is that the same situation in a 6.2 liter v8
Gage McNeece yes, afm is something built into all gm trucks from factory
How is the fuel mileage now. Are you still doing better than before the program 🤔?
off topic. Has your new chevy ever show you a stabilitrak service on your dash?
Raul Cantu I had that issue with my ‘14 Silverado 1500. Then it got worse and started reading anti theft warning and wouldn’t start. I found this video and read more about it. Figured I would try it and see. My grounds weren’t that bad but I cleaned both of them under the dash pad and added dielectric grease and haven’t had any issues in 6 months.
