- WARNING!: use this at your own risk! , this successfully overrides MDS but could result in some weird behavior of the transmission over long use, as i was not aware of during filming, but later on screwed my truck up. Thank you

OR..just drive over 65 mph all the time, I found that, that light don’t come on anymore. And comparing it to the 1500 ram I had with the 5.7L , it’s a different tune on the 6.4, it’s only on when going downhill,coasting,or you just had to let off the gas. Once it gets down to around 10 or 15 mph it goes off. The 1500 5.7, hell it seems like it was on a lot , you could even gently go on the gas and gain speed with the ECO light on (sounds like shit tho) where as the 6.4 it won’t do that...so HAMMER DOWN!😜🤣🤣🍻👊🏻good video!
BR Outdoorz Good info !! I figured the tunes and characteristics were different from both hemi engines . The 1500s get rated mpg by the EPA, while the HD trucks don't , that's why the 1500 tries like crazy to conserve fuel I bet. I'll pin your comment 👍😎🍻
IWrocker lol thanks...that 1500 SLT had the 20” wheel option, with 3.21:1 rear axle ratio, so, if your not heavier on the throttle, it sounded like a gut less 4 banger in need of repair, drive me nuts!! 🤣🤣
BR Outdoorz ouch that is a bad wheel and axle ratio ! Gotta say I'm still impressed with the 6.4L and 4.10s ... makes for a nice peppy truck 💪
IWrocker Fuck yeah it does!!!! 🤣Even tho the power wagon costs a little more to operate, I don’t miss that 1500 at all! 👍🏻😎(😢out of beer sorry😢)
Is the shifter method permanent? We don't buy em for the mileage..
Today bud Your video was by far the most useful for my truck to date
Thanks for explaining that. I've been using the down 'shifter' for going downhills, and haven't used the tow haul at all. Now I know that tow haul might be the best way to go in the sierra hills and offcourse when towing.
Tow/Haul doesn't work for everyone but the +- shifter seems to work for all RAMs that have this feature. Thanks for the video! It helped me get rid of that damn MDS.
is it necessary EVERY time you start truck?
@@robinkuruda5249 Yes. It doesn't remember. You even have to do it again if you switch to Park, Reverse or Neutral. But it works.
i have a 2012 only draw back to using the "tow/haul" mode with the 6 speed it wont use 6th gear while using that mode, but the manuel shift mode works fine, just set it on 6th gear and drive!!!
Thanks bro! Just bought a 17 2500 6.4 . First drive was shifting excessively. You just cleared it all up. Thank you very much!
Went out just now in my 17 Power Wagon...confirm...ECO does not come on ever on tow/haul mode. Much better driving around in that mode. Especially with my muffler delete setup..like you...sounds awesome all the time then. And I like the shifting in TOW/HAUL mode. Have a great weekend buddy!
HotRodHarrys Yea it really livens up the truck right!? Have a great weekend bud!
tow/haul mode increases your rpms at speed compared to having it disabled. it also makes your truck gear brake down hills instead of just coasting when you're not in T/H mode. T/H kills my mpgs even worse than the HEMI already does without it.
TOW/HAUL does it over work the engine? If you were to use it as a daily driving
Just put it in the highest gear instead of drive and then you shouldn't have to worry about it kicking into MDS and it will not increase your RPMs or gear break in my 2011 I just keep it in 5th unless I'm playing and shifting through the gears manually in the 6 speed and 8 speed trucks you would just put them in 6 or 8 I'm going to bypass the MDS system when I install my cam
Realize, that your mds lifters are actually getting more oil in 4 cyl mode.
Oil pressure to the lifter bore is what lets the lifter collapse.
The best way to do this is delete the mds solenoids with the proper plugs, and replace your lifters, and get a tune. Then the lifter bores get xtra oil all the time.
Ive noticed about 3 mpg difference in my challenger but im sure a heavy truck gets less.
It’s the non mds lifters in that engine that fail as they are starved of oil I’m told.
THANKS MAN. THATWAS VERY HELPFUL. THINK THATS WHY THE LIFTERS ARE FAILING ON THESE HEMIS AT SUCH A LOW RPM THEY ARE’NT GETTING ENOUGH OIL. THESE ENGINES LIKE TO REV. HIGHER RPM KEEPS EVERYTHING HAPPY.
I love the sound and setup. Btw the dash, aircon, radio setup to look like a ram front-awesome. If you didn't realise go back to where rocker is playing with radio or something, the whole mid dash looks like a ram grill etc
I did this in my Jeep Grand Cherokee and I put 130k and no lifter issues. Also I drove from Orlando to Miami with eco mode on, then drove back to Orlando in all 8 cylinders and the fuel mileage was exactly the same. It doesn’t save you any gas. All it does is destroys your motor.
Had a 1500. While I agree with this if you don't want to buy a tuner...the tuner has wheel correction, transmission tuning, engine tuning, etc. Living in the mountains at 4500 ft up to 10,000 feet it really helps the truck. I gained 3 mpg on a mountain loop over stock.
what brand/type of tuner, just got a 2016 1500 classic and am not happy about 4 cylinders just hangin out doin damage to cam/lifters
@@lawrencejoy9346 I got a Flashpaq F5 but don't have the truck anymore. It was great while I had it though.
That should have been a 10 second video. Put it in manual mode and MDS will not come on..done.
Fact !!!! That's what I do with my 2013
Um..no I'm a complete nubee. Every moment of this video was worth it. I've had this truck 2 years and still only just found out how to turn on and off the fog lights. Yes some of us are hope.ess specimens.
Literally first thing he mentioned
Or you get your ECU reprogrammed and you will never have to use manual mode ever again.
@@wendygerrish4964 exactly.
In the case of the 5.7 Hemi, one of the inherent reported problems was cam wear over time. In further researching this the cams that were wearing done were the cams related to the cylinders shut down by the MSD system. My solution has been as you show switching out of ECO mode. Using the Tow button lowers gas mileage (it is the same as putting a performance chip in the unit). As far as gas mileage, (200,000 miles and still sounding like a new engine) the ECO mode actually improves very little over turning it off. You need to burn the same amount energy to maintain the same speed running four or eight cylinders. I know some would dispute said statement but it is true. The computer compensates with fuel to the injectors to make up the difference.
What tuner did you use?
The reason the roads are so bad is because someone decided to remove all the feet pads on the snow blades. .now the actual blade scrapes the road instead of being up a bit. .so everything it hits it chips up..thanks smart person for all of the pot holes
Best 6min video to get to know workaround my truck, nice.
Been looking to get a tune on my dads truck and when I get one soon just for this shitty mds, you’re a lifesaver my guy
the best informative video about ECO mode on a ram , ill try the tow haul mode !!
I own a 2015 ram with the 5.7 and 8 speed trans. my truck will run mds at any speed under 75 usually with Hwy tires and good gas but when it comes to a half ton ram 2015 - 2019 classic the only way to disable MDS it to turn manual mode on turning tow and haul on does not disable mds in the half ton line The only issues with mds I’ve personally seen are with the mds lifters because of the size/weight of the mds lifters they can wear out faster than traditional lifters at least that’s my understanding I like mds at certain cruising speeds but if the rpms are too low it makes a little vibration I don’t like. I recently bought a 2019 with e torque and it doesn’t seem to go into mds mode as often and there is no mds vibration/shutter the transmission also seems a little smoother although it’s the same trans as my 2015. I’ve had many rams over the years with and without mds, I’ve never had major problems with any of them
dragging around four dead cylinders...that would be like I was married all over again
🤣
@@stumplimit I may be wrong, but I believe only the intake valve is closed. I'm Pretty sure I'm right. Ah, what the heck do I know.. I'm never right. At least that's what I've been told by my Wife
@@stumplimit You know what, I never thought of that. I appreciate your defense of the non-use the MDS system. Not only that, I agree with you about not using it and disable it every time I get my truck into Drive. The drive-by-wire and soft shifting transmission are enough of a delay in responsivness. The point of my message wasn't disagree with you. Maybe we both need to do some research, but at the moment I don't like the idea a four cylinders shutting down. For one thing the exhaust sounds different and not in a good way. But what really makes me think it maybe isn't the best idea is because I know that in a multi cylinder engine, smooth operation, power generation and sound are somewhat affected by the Scavenging effect from running cylinders. So... I don't know.. maybe this isn't an issue on Modern engines. I still own a 78 Ford for crying out loud
In Cognito
Lmao😂
Lmao
Appreciate the video . I have a big horn 1500 2015 & have wonder about the plus & minus buttons. Thanks for the video
Always been a Gm fan,recently got a ram 1500 for a nice deal however and I noticed it’d “bubble” I figured it’s in 4 cyl sure enough I was right, thanks for the video really annoys me with the excessive shifts
in a 1500 with an 8 speed tow haul doesnt deactivate it, but putting the trans into "manual mode" does.
How do you put it in manual mode
Just use the gear limiter buttons on the steering wheel. If your in "manual" mode it disables mds. You can just use the +/- put it in 8th & it will shift like normal with no mds
Thats what I have been doing with the 2023 Ram 2500 6.4 Big Horn I just bought. Hope it doesn't hurt it in the long run...
The column shifter is on the 6 speed Ram 1500s, the dial shifter is on the 8 speed Ram 1500s. Not sure if that is still true in the HD models
Very helpful TY for the video! BTW Illinois does suck lol
My 2012 Laramie 1500 5.7 4x4 has this MDS and it sucks. It gives our engines cam issues, worn lobes, or timing chain issues. Very dumb design. I deactivate mine by keeping it in manual mode, and keep my gear on the highest level. Thats 5 for my model. I have a 545RFE transmission, with 201k miles, luckily I haven’t had any “Major” problems other than replacing the clutch packs in my tranny, but just regular maintenance was required on a few small items, alternator, starter, and brake replacement a couple times.
I changed the belt twice, once at 100k, the other at 200k, and just changed my shocks all the way around.
I lucked out, My Ram has been real good to me, I maintain it regularly, definitely keep the oil changed in these every 5-6k, the internals will last a lot longer, and use full advanced synthetic oil by mobile 1, with an added half qrt of lucas oil stabilizer. Thats what I e been doing the entire time, and it’s obviously paid off.
Nice vid guy.
It will still shift past the number you set it at. It will just hit max rpm before shifting. At least from my experience. Won't even hit rev limiter just shifts where it would if you where to floor it.
With price of gas in Canada jumping up everyday I am starting to appreciate my MDS!
Gives me another 50-75 km in a tank on my 05 Magnum RT
did you do the math ,i.e. is that somewhat accurate.
My truck actually gets better MPGs without the MDS in combined driving but I live in the middle of nowhere Tennessee and most of my driving is on back roads..
Hey do you still have that 05 Magnum did your engine ever f******
@@abdullahameen6047
I still do half that car, although the engine failed around 300 km. So I replaced it with another Hemi from a 300 C.
@@babak1969van yeah I just replaced mine with an engine from a Jeep Commander with 75000 miles on it seen this video I do have a check engine light for a cylinder 1 deactivation
You had me at quick & straight-to-the-point 👍
Only problem doing it the way you say is that you will get worse fuel mileage due to the truck not being in it's highest gear. I have a tunner that shuts MDS off and let's it go into high gear
What Brand Please.
I think that the best reason to delete the MDS is that the oil flow will be better to all the cylinders with the MDS out and those plugs in. The lifters would get better oiling. I wish I knew about that a week ago before my 2 cylinder started misfiring. Its not the plugs, coils or injector and it has a dead spot when cranking. I don't know how I'm going to pay to get this fixed either?
Love your TH-cam videos I have a few questions regarding upgrades for better performance on my 2016 wagon.
Just tried this on my 2021 DT 1500 Laramie with E-Torque Tow haul cancels out MDS on mine awesome thanks
So I have a 14 ram 1500 hemi. I have the 8 speed transmission. Found out the tow haul won't shut off the eco mode or the shifter buttons on the steering wheel. On the radio go to settings then display scole down to fuel saver it should be on press off and it won't come on again. So you can do this instead of spending money on programming
Didn't know that info. Ram all the way!
With MDS on it sounds like a tractor and I actually like it
Turn off MDS. Save the lobes on the camshaft from wearing down.
th-cam.com/video/9Iv46wEVZWs/w-d-xo.html
So how did it screw up your transmission?
Haha might work on the 6.4 and maybe some of the newer trucks, but kills fuel economy on my 2012. First of all the tow/haul mode on my truck just completely disables 6th gear. I guess it can be said that the eco mode did not come on at all, but I also burnt half a tank of gas in a day of my normal driving. Also the gear select on the older trucks (at least mine) does not disable MDS according to my cluster, however does seem to give slightly better response.
that sounds like a exhaust brake on a truck lol I kind of like it
My 2017 tow/haul mode mds still kicks in.
I have a 13 and it doesn't come on with tow haul on... guess they changed it... its stupid if you're hauling you want all 8 cylinders running
@Put'URmouth ONtheCURB you are correct... its not suppose to activate
@@scottrussell6717 If you have any weight behind the truck eco mode won’t engage in the first place so that argument is in invalid.
What I hate the most is the vibrations from the 4 cylinders eco crap :/
viajes80 I don’t have much issue with that part. Clearly it is an issue though because they have that vibration compensator on the 2019.
My Jeep Grand Cherokee with 5.7 had terrible vibration too. ended up buying a programmer and turned MDS off. Unfortunatly MPG's suffer
@@famousmidnight what programer?
@@babylove-69 Diablo t1000 A newer version is available now. There are other brands with less of a Price tag.
Not to mention the awful amount of engine noise at idle.. sounds like its got lifter tick and sounds like shit..
What I don't get is why they don't give you an option to just disable it on the display completely like on the Hellcat you have an option to leave it in 707 horsepower mode all the time or 500 horsepower or eco mode
putting it in manual mode deactivates MDS in the 8 speed.
Sir Brellin Correct. I do it every time I get in the truck. The “tow/haul” trick does not work on the 1500’s with the 8 speed auto.
It does in my 2011 5 speed shiftabul automatic as well
It also deactivates eco on my 2013 6 speed .
I have had some people say yeah but you disable the Eco and it hurt your gas mileage. Well I have taken my truck out and run the cruise control with the Eco shut off between 55 and 60 mile per hour on our secondary roads, and I seen maybe only a mile per gallon difference. But honestly I did not buy this thing for the mileage I bought it for the looks. So in my opinion screw mileage. When I get in that thing and fill it up with gas I'm heading somewhere where I don't give a s*** about mileage LOL. So just use the paddle shifter depending on what transmission you have, mine has the 2013 6 Speed, and run it off from eco. Have not noticed any issues, no noises... Nothing
Caddillac used the mds years ago it was a disaster back then i had a caddillac with it and it was a disaster ! I took it out after blowing head gaskets twice ! Im sure if it gave caddillac head problems its probably going to give a hemi head issues especially with aluminum heads on a cast iron block.
I'm in central Illinois. Just got a 17 Ram 2500 6.4, crew cab long bed.
2019 - RAM 1500 5th Gen's don't have the ECO mode. Tow/Haul is the only way to disengage the MDS System...(I was wondering if the 6.4 Hemi's had MDA).
I have a 2011 sport 5.7/ 5spd with MDS and I have never noticed a change in sound or anything that corresponds with that system engaging / disengaging. I do however notice a difference in RPM at highway speeds if I opt to manually shift down to 5 with the stick. The ECO light goes out and my RPMs hop up a few hundred reminiscent of a lockup converter disengaging or coming out of OD. Upon clicking the stick to + the ECO indicator comes back on (no change in sound) but the RPMs drop back down again. So at the risk of saving my engine by not engaging the MDS system, some of you stand by your claim that there's no savings in mileage with MDS as compared to no MDS, cruising at 65mph and 400-500 more RPM as opposed to letting the MDS shut off 4 injectors and run at 500 lower RPM????
just hitting tow haul mode button so eco mode shut off seems an easy work around. Only time active fuel management helps is when u r already doing 60mph no need to drive V8 cruising hwy no load & not towing. City driving or less rpm-s r so low w/V8 not worth the risk to engine for no real fuel savings. Ppl r talking about 1 mpg extra using vs not using but not reach 200k if u use active fuel MDS system, & instead mayb u get to 150 k range b4 hving to rebuild head $2500-$3k ish in repairs. Bad math if u only save 1 mpg, not worth the risk, but if u r on interstate & can save 2 mpg using MDS vs not then math make good math cents, ie pound smart.
so what kind of mpg are you getting overall with the 6.4? Your truck is the exact one I wanna get!
Interesting. On my 2015 6 speed when I navigate to fuel saver mode. I have two choices. ON or OFF. When I push Off and done the eco mode stays off. Even when turning the truck off and then starting. I manually need to go back to fuel saver mode and push the On and then done.
Hey. Thanks for the video. Did the exact thing. Though trial and error. 👍
I have 6.4 Mega Cab and I don't think MDS comes on nearly enough. I wish I could manually keep it engaged.
Turn off MDS. Save the lobes on the camshaft from wearing down.

2014 RAM 1500, 5.7, 8 speed here: tow/haul does not turn off ECO mode. The only way is to use the steering wheel buttons
I bought a Borla cat back. I don't notice the tone difference between the 8 and 4 cylinder modes
What did you get for a borla kit ?
@@christiansmit2515
Touring
MDS is also on the 6 and there is no issue at all. Why? I am over 200K miles and still going.
MAN that thing is a beast!
amen hellinois roads are bad, also my problem here was deer.deer proofed my truck so im good now:)
My 06 2500HD doesn't have MDS. Only the 1500's had MDS on the third gen trucks.
Awesome informational educational video experience Y'alls
My shifter ain't goofy buddy. It's misunderstood. 😅
How do I deactivate the mds for a 2017 DodgeDurango RT?? Many thkx and big like😎🙏
I have a 2012 Ram express , I put it in 6th gear all the time , truck is faster and takes off faster too and my glasspack sounds way better !!
You can also just disconnect the oil pressure sensor.
Video was the answer. Thank you!
Our RAM 3500 is nowhere near that noisy. The Police would take us off the road if it was. It has a Cummins Semi Trailer motor. Used mostly to pull a caravan with the tow haul mode on. They put your steering wheel on the wrong side.
Remove MDS solenoids, cap all 4 ports and disconnect the wires. Change lifters to non MDS and get a tuner to turn off the MDS so your check engine light doesn't come on.
Do you have to turn it off everytime you get in the truck? Or does it stay off? Also how much does it affect gas mileage?
Only other factor is if driving up north snow & other bad weather driving vs california perfectly clean safe drive conditions. All wheel drive hurts MPG better to go part time 4 wheel drive vs all wheel drive+ real 4 by 4 can go where all wheel drive or electronic 4 by 4 SUV drive can't go. Again hard to beat car front drive & SUV or truck part or full 4 by 4 ride sizing driving to the task, or bad weather, 2 beats 1, pick what & when u drive 2 older tech vs 1 newer nicer tech car w/payment.
Tow/haul down shifts a gear also.
I have a Jeep Commander with Hemi and I wished the MDS was MORE AGGRESSIVE. So how can I make it stay on longer???????????????????
Great tip. Thanks for posting. 👍🏼
I have a 2014 1500 the gear limiter worked but when I tried tow/haul echo still came on.
On my 2017 ram when in tow it's like it won't shift all the a way to 6 wish there was a way I could get my tpms trash hold lowered so I wouldn't have to clear it out every time I crank it
Good vid and yes, Illinois roads suck! I'm all familiar with them.
Thanks for the information good instructions
In Grand Chreokees, you just run on towing.
Are you sure your truck didn't fail because you were beating it?
So what your saying is you should have gotten a tuner bc it screw up your transmission
2009 4th Gen here. Truck just started shuddering here and there in fuel saver mode. My shifter is not on the steering wheel
The plus/minus buttons should be on the column shifter. Simply press the minus button once until you see a 5 on the dash indicating the highest gear it will go into is 5th, thus deactivating mds.
So buying new, go cross over vs old devil smack MDS active fuel BS truck or diesel oldest tech in 2021 but in fall hopefully ppl can buy & drive what they want again Big full sized truck or SUV again & clean burn tech or electric tech or mix or hydrogen tech will make it poss.
Love the channel !
What exhaust do you have?
You got a like on this video as soon as I heard "Illinois sucks".....
Sorry to say but I cannot stand Illinois for so many reasons... On my way out soon lol
Do you have to do this everytime you start the truck? Or does it save your settings?
Roads look smooth compared to Nampa Idaho's Roads.....(been on smoother jeep trails)
I thought you can hust turn off eco mode from display lol 😂
I was on the freeway with my ram that I recently purchased it’s used a 2014 1500. Accelerated and the motor cut out at 104 Mph it was like a governor kicked in with that be the MDS? Let me know thanks
Eco mode on my 1500 doesn’t mean mds is active it just means you are driving at the prime rpm they think you’ll get good fuel mileage.
Michael interesting. On mine you can clearly hear the changeover in person with the loud exhaust , and my eco light goes hand in hand with the sound change hence 8 cylinders to 4
I’ll try to get some video tonight. I have a 17 ram 1500 hemi. It’s got a straight pipe so easy to hear the mds. I know it turns off mds with the shift indicator set to 8. I hadn’t tried the tow haul.
Kevin Noll what will?
Sorry Michael but that is incorrect.
Jonny Morrill I will politely disagree. The eco mode doesn’t correlate to mds being active. You can ride all day long on eco mode and not be in 4 cylinder mode. There is a distinct sound in 4 cylinder mode and it’s even more pronounced with no muffler.
Good explanation 👏
In the left gauge cluster what does that icon with the up and down arrows with the truck in the middle mean? It looks like the wheels and tires glow orange. I can’t find it any where.
My 2016 2500 with 5.7 doesn't show a green light for Evo mode coming on. How can I tell if it's got mds
Dude I'm so glad I found your channel, I baby my sport lol. Your truck is sick, love it . I want to get an exhaust system, any recommendations? 🤘🤘🤘🤘
Corey Kearns thanks man! I def suggest Magnaflow or black widow for the Hemi . Or straight side pipe like my setup ! Haha sounds amazing in person
Carven!!!
I would say Corsa i have it on my 2012 Grand cherokee 5.7 and it sounds great
I have flowmasters on my dodge hemi 1500 and sounds deep and loud I get plenty of complaints from it being to loud😂
Flowmaster super 10
If I would run in Tow Haul 100% what would it do for gas milage? My truck is a 2010 1500. Thanks
2500 or bigger don’t have MDS I was told ? I have a 2010 powerwagon no MDS
This could easily be a 30 second video

At least it ain't 30 minutes with some dummy not knowing what the hell is going on.
IWrocker, I watched this video yesterday (3/7/20). So, this morning on my way to work, I tried the tow/haul mode 1st. My mds/eco mode kicked in after 35mph. However, by using gear selection plus/minus it kept my mds/eco shut off. Thank you for the video.
Do you know if programmers can deactivate the mds permanently?
@Flip Loco my ram is a 14. I've gotta keep it in the gear mode, in order to not have eco kill my exhaust note. I'll probably have to get non mds lifters, a mild cam and tuner to deactivate completely.
Non mds lifters, a cam, and a tune will do that for you bud
how do you verify that it isn’t just the eco mode indicator not coming on?
My 2016 Ram 1500 CCSB 4x4 Lonestar still has MDS when in Tow/Haul mode, even when I’m pulling my 28’ camper at 7k lbs.
Wtf why would FCA think that is a good idea to have 4 cyl running when hauling????
Turn off MDS. Save the lobes on the camshaft from wearing down.
