These videos are great! It’s a steep learning curve and you’ve helped me understand a ton already and I’m only halfway through the videos. I got sick of dickhead tuners treating me like crap and making me bend over backwards for bad tunes so decided to teach myself and you’ve been a huge help so thanks! Keep the videos coming!
Mhave watched several tuning channel's using hp tuners... Felt overwhelmed every time... Until I stumbled across this channel... Thanks for the content man
Cant thank you enough for these videos. Ive been building engines and cars for a long time, but always leaned on others for tuning. Ordering hp for my 15 Camaro ss and going to start trying it myself. These vids are pushing me to it and making things make more sense. Thanks!!
Thank you again, great video I didn’t understand why you are smoothing the VE table cells vertically and sometimes horizontally ? What is the principle for the selection pattern ?

@@GoatRopeGarage - So got a question when setting up my VVE log table, I noticed you your VVE table says MAP/Baro , on my system mine only Says MAP. Do I still use the same user defined Math you setup with MAP/Baro? I assume I would but wanted to ask.
Nope, you want to use what you have on your VE table, so most likely yours is in kPa and reading straight from the map sensor so when you log the map sensor (hi res is there is an option between high and low, usually the low res is marked and the high resolution is probably just listed as the map sensor) you will bring that in for your rows with your RPM for your columns then setup your EQ error ratio. '09 should have EQ ratio commanded as a logging option so that part should be like how it's done in the video.
Goat Rope Garage well then glad i asked! So id like to say i followed you completely but u lost me a bit with the hi/lo res stuff... So my rows should just be my MAP only with parameter set to MAP sensor?
This is an amazing tutorial. I have to give you some major props, you explain things clearly and easily. I’m extremely new to most of this and you make it understandable and I can’t thank you enough !!!
I run a gm ECU commonly referred to as a '165' ECU from a 86-89 camaro or firebird on my gen 1 sbc. It is originally a MAF ECU but I am running modified code from Australia called OSE12P. This allows me to use a MAP sensor and speed density instead. I use tuner pro to tune my ECU. It's interesting to see how much has changed and how much is similar and different with the tuning software and tuning methods. Keep up the good work
Thank you for this series! so much of what I see is for the older version of HP Tunes, and as a rookie to this and a visual learner, I have struggled to follow it. Couple that with crazy stuff like random misfire means you have a cam, and Long term fuel trims rich can mean rich or lean, and even this Georgia Tech engineer can get lost !
Just wanted to say that you and your content are greatly appreciated! Planning on diving into the HPTuner ecosystem over the summer for my little fiesta. It's no Corvette or mustang, but it's fun to throw around corners! It's a '16 Fiesta SFE, it comes with a turbocharged inline 3 from the factory. Learning all I can before I start tinkering with the ECU, don't wanna hear a knock knock joke from a cylinder!
Just found your videos. Absolutely awesome job dude. I’m learning so much. Hopefully I can apply some of this to tuning my Ford 3v mustang. Just ordered HPT and an AEM wideband! So stoked.
Thank you so much. I paid for the full genIII and gen IV course from the tuning school… your content is really supplementary to their course and have allowed me to tune a few family cars as well as my own challenger RT
This series is extremely informative, I'm on the fence about getting an mpvi2 and tuning my Barra... This is making me more confident, I think I'm just gonna commit and get myself one.
Thank you for all of your wisdom and willingness to show us your knowledge. Looking for a good baseline, on how long on average should it take to time a car from start to finish.
Because of your videos, I am doing my own tuning now. This is the first time tuning VVE and this video was imperative to my progress. The only question I have is some cells are showing negative and some cells are showing positive. The cells that are showing a positive number are the cells that have not been populated previously. Is this normal? When I switch from a one bar to a three bar map sensor, a lot of the data at the bottom of the graph was a negative number. I went and populated the areas where I'm operating with some numbers and it seems to be working better. Currently I'm able to get up to about 5,100 RPMs before I start getting the fuel cut off but as I build the cells it is getting better and better. You are right, you do have to do this a lot.
EXCEPTIONAL VIDEO - I've been looking and hoping for ages a good tuning channel would emerge and SD is my focus area at the moment. I am still in the learning phase but can log pretty well and know what needs changes "but its how to make the changes where I needed help"...... In my scenario I know that my tune is SPOT ON except when I am WOT I am running very rich 10.5 ... High 9's. So I am working to figure lean out that area of my VE fuel tables. I think with your videos it will help me a great deal.
Let me know if you have any questions as you get more into it or if you need certain things addressed. Trying to create a repository of information for people to reference so it will be ever evolving.
Would be neat to have a winter tune and summer SD tune in areas that have crazy weather (Texas). Probably good to run dynamic though in areas with quick weather changes, right? Texas can be 80F one day and 30F the next.
Hey enjoy the videos I don’t know if you know this but in the compare files if you go to differences and put 0 in it will put it back to normal so you don’t have to keep switching back and forth. After you’re finishing tuning
Brought up 2 questions for me: 1.) In your logging you had to create a graph that matched the VE table. Seems that’s a pretty important table why would HP Tuners not already have that as something to choose from in loggingsince it’s so important? Why’d you have to make it manually? 2.) After your scan you copied and pasted and did multiply percentage by half. Why? Why not multiply by full amount? Pick any cell from your scan. What does the value in that cell mean and what is being read to come up with the value? I mean how did it know you were 11% lean when you first fired it up? Is it showing how car off you were from what was in the table in the tune? And after your pasted value is in that table what did it change? So finish this sentence: Now that the value here’s has changed to this, it will cause ______________ to happen thus making the tune better. Thx
Alright... Your giving out decent info and laying it out in a way a normal person can understand. Probably the best i seen. So props man. Even if i hate your prejudice against afr lol Keep bringing the content BUT... i havent tuned any gen 5... but anything else i have tuned... Speed density tuning should be done before maf!! Anything you do on maf will need to be redone if you change the VE table. Few pointers for viewers. You' ll run into odd stuff that will make you nearly lose your mind. With some of the "newer" gm vehicles (07+), when there is a airflow related DTC, your transmission will default to max line pressure. You will need to disable this in the trans tune. It will blow rubber tranny cooler lines lol ask me how i know. Older stuff like the p59 dont really have this probelm Had a e38 that would not idle with the maf failed. Nobody on the efilive side heard of the issue. But found a table described as "Maximum effective throttle area of the ETC in square millimeters with DTC" table had something like 60 in it where its related table (minus the DTC part) was 6500. put 6500 in the other table and boom problem gone and i can tune the VE. Stuff like this will drive you mad. And it usually takes lots of searches on the forums and time browsing the tables. Little trial and error. Move slow and dont change a bunch of things at a time or you'll end up starting from square one a lot. Learning on a close to stock engine first helps. Big cam/heads can get a bit tricky for your first go lol
Both are tuned independently, when you do MAF you're disabling SD and vice versa, so as long as you're doing it correctly it doesn't matter what order you do it in. I suggest MAF first because you can get a vehicle up and running on a MAF only tune in about 30 minutes where as a SD tune can take days to dial in with street tuning. It may be that EFI Live doesn't give you a proper way of disabling dynamic airflow, which in that case you would need to do SD first but that isn't an issue with HP Tuners.
These videos are great. I've been tuning for years, and still learn a little from each. Sure do wish HPT would automatically disconnect the scanner when you try to write a tune though. Catches me every time too.
Been hesitant to get hp tuners but feeling more and more confident thanks to you. If you were able to release more videos in regusrds to 4 cylinders by dodge mainly forced induction that would be awesome.
Just want to first of thank you for your time spent to help us out with tuning our cars, or at least helping us learn the basics. This is my first attempt at tuning. My question is for my '09 G8 GT 6.0l. I dont have the option to disable O2 READINESS VOLTAGE. I just unplugged bank1 sensor1 to stop closed loop. How would you recommend getting around this in the future? Im working with MPVI2 Pro.
Best home tuning info on the interwebs. I've noticed on my SD logging (gen 3) that under 30 kPa in the upper RPMs its always super lean. Only get into those cells with closed throttle on decel. DFCO is disabled. You ever see that?
I want to start by saying that these videos have helped me understand HP Tuners when others couldn’t. Thank you. I’m hoping someone can help me. I have 2.2 auto supercharged cobalt and at 47%+ throttle I hit “2step” at 3700-4000rpm every time. If I go WOT no issues in that range, as long as I’m not in the 2 step mode. Before I was supercharged there was no issues whatsoever with the car. I feel that I should add that I can build max boost while in this 2 step mode. Also it won’t do it in the first two gears. Can’t say anything about third because it shifts to fourth right before this. Any insight will be appreciated as I’ve been battling this for months
Without having someone making videos like yours.. how in the heck does someone figure all this crap out!? I feel like that old TV show "Greatest American Hero" where he finds a suit that gives him super powers, but he lost the user manual and is just trying to figure it out via trial and error. Thanks for the vids.. I'm going to go take some ibuprofen now..
thank you for the video and for asking for our feedback and questions, so I realize we disabled Closed Loop, but we did not disable the LTFTs and STFTs and I see guys in other videos do it in addition to disabling Closed Loop, is that unnecessary?
It's a double redundant thing, nothing wrong with doing it but it most situations once you disable closed loop the LTFTs go to zero. Log them and see, if they don't when you've disabled closed loop go ahead and disable LTFT too.
@@GoatRopeGarage I really appreciate you taking the time to respond, thank you so much, keep in mind I am never questioning your experience just asking to learn.
lots of info to take in, im on ecmlink for dsm, on speed density, wish i knew about your channel before sending my car off to english racing lol,. im still trying to learn all this tuning. im mechanically inclined but tuning stuff is on another level..hopefully in the future ill be able to mess with a more cheaply built engine,,
What gen is this? Have a 14 Camaro SS LS3. It took me a minute to figure out My VE table row axis uses MAP kPa and not pressure ratio. I deleted the Pressure Ratio Math and modified the Graph row axis to MAP kPa. Now it logs. It helped me to add a chart row with EQ Cmd, EQ, and MAP kPa to monitor the variance.
I've been binge watching these videos in preparation for a project I plan to be working on, 5.3L swap in a 2nd gen camaro, they've been very informative. One question I have regarding speed density tuning with HP Tuners like you are: Is it necessary to keep the MAF sensor when doing speed density tuning? A project I got running recently I used a holley terminator x for a twin turbo 4.8L (2.5 bar Map sensor and IAT sensor in the engine harness). I was hoping to be able to tune the stock ecu I'm using for this next project (5.3, 2nd gen camaro) with speed density since I'm somewhat familiar with it already. It looks to me like I'd be able to break out the 2 IAT wires (signal/gnd) from the MAF sensor and run it to an IAT sensor. For the MAP sensor, according to the lt1swap website for a 2004 4.8/5.3/6.0, the pcm has a low and 5v reference already with no wire pinned to the MAP signal. Can I just run the MAP sensor signal wire to this pin on the PCM to have a functioning MAP + IAT sensor setup to setup a speed density tune? Thanks for any feedback , if not, I'm sure I'll get it figured out as I watch more videos/read more forum posts. Thanks!
If you have a 5 wire MAF and want to go MAFless, can't you simply force the MAF to error out via a DTC. Wouldn't the IAT sensor still function with the 5 wire connection plugged in ? Early in the video there was mention of needing a separate IAT sensor and break out harness ?
Very nice video. Thanks for taking the time to get into so much depth and detail. I’m trying to SD tune the VVE table on a E67 controller. I am running into issues though by hitting reduced power mode. Any tips or tricks to not enable RP mode?
Awesome videos , great at explaining clearly on how to tune. I have one issue that I need to share. My car is manual. Everytime I about to slow down, e.g., from 2000revs and when it hits roughly 1200revs, my car go lean , AFR gauge from normal to over 20 then no reading. It only does it at low rev slowing down on the same gear. Can anyone be able to help me where to tune this area
My question is the when you go into the ve table you have the light red blocks and the full colored blocks. Are the light blocks (transparent) the blocks you collected data on and the color ones is data you didn’t? Or is it showing you the massive difference
Any chance you can do some turbo tuning, boost tuning with pump gas and meth? I've read you can do things with timing to help spool the turbo and help load converter. Great videos, thank you!!!
The standard tuning process is the same, I am going to have a video coming out soon about tuning with the addition of meth injection as I am about to double my injection rate. It is pretty straight forward though, you still do what you would normally do on the MAF and SD tunes, you just need to take it slow and as you start working into your meth ramp in you'll run rich which gives you an area to start pulling your fuel out if need be. As far as the second thing, you can do some things on timing to help build boost off the line but I'm not sure how friendly it is on your motor. Probably something I would steer away from unless on a purpose built race car.
Thanks for your videos. I'm just getting into the tuning with a Holley Sniper on a 85 K10 350. Did you ever do any videos with the Sniper? Would love to get your input and expertise on it.
Second question since you answered my first one, show's the channel is not abandoned. Guys also disable Traction Control, can you comment on that and why you didn't?, we are talking about Gen III GM Vortec engines, 4.8, 5.3, 6.0 etc. 1999-2007 does Traction Control impact fuel/air delivery or does it not, also they do it under both Engine and Transmission tabs in HP Tuners. Thank you in advance.
On Gen III platforms your traction control is spark based, shouldn't really get into it when tuning fueling. Later generations can pull power through ETC but that's not going to change anything from an airflow tuning perspective, if it pinched back to control traction it's just going to shift the area if the map you're in accordingly.
I’m confused by the step when you multiply the tune by the values from your scan. I understand they are percentages, but why does pasting special-multiply actually end up adding the percent to the cell’s value. It’s like it actually multiplied the cell by 105% (which is what you want), for example, rather than multiplying by 5%.
Hey your videos are awesome and I played like three times each to assimilate all your info but, How do you connect the wideband to be read? Also if I follow all your steps very careful , it is probably to blow a motor? Hahaha and an universal question all the tunings followed exact as you shown can be applied to different car brands that hptunners allow (Nissan, ford,dodge)? Sorry for a lot of questions I know you are very expert😎 and I'll be very grateful if you answer me, good vibes!
great videos, you have saved me so much time! I was able to log my AEM thru the serial by watching your video and a million other tricks. On this video I have one area I don't understand. In high load rpm if you use the lambda and multiply the base map you are pushing towards 1 lambda which I understand for cruising, but you would want approximately 0.85 in high load rpm situation?? I understand not wanting to disable power enrich but that is effecting your wide band readings which when you multiple will drive the overall ratio to 1 versus .85 is high load. What am I missing?
Thank you for the video we learned a lot. I just want to ask you why are you dividing the data by have before applying? I guess this delaying the process. The software should suggest the corrections without the need to modify the numbers based on the AFR reading. Can you explain why are you dividing by 2? Thanks
Just got HP tuners and I'm going through your tuning series. Definitely been over the speed density video a lot haha. I have a 13 Explorer EcoBoost I just put stage 3 turbos on but this thing has six speed density maps ???? Is this a case where I'd be tuning all these SD tables?
Great videos! Thanks... I am new to tuning... want to tune my 95 Lingenfelter Suburban with a 605. Do you ever use TunerProRT? I dont think HP will work with my truck.
Hi just wanted to let you know thank you for sharing your knowledge it's teaching me alot I am stuck with my turbo Camaro on e85 my afr at idle is at 10.9 to 11 I know that's rich and when I drive the car and floor it it goes to 16 and sometimes 15 afr is that bad
I tried to start sd tuning. It’s super rich and went into limp mode when I drove it. Did I miss something? E67 gen iv. Thanks for everything you do for us!
So when you're logging, the values populating the cells are the % error from a proper air/fuel ratio, negative values being rich, and positive values being lean, right?
This is awesome. Just a suggestion - couldyou do a vid that runs through the tables for air, fuel and spark? Not how to tune them, just a few sentences on what the main tables do and when they are used. It would be a supplemental 1.1 intro vid. Just a suggestion. These videos are great.
Wow, great content! Looking for some context though. Seems as if you manually put the ECU into speed density mode, ran the car around, and relied on the ECU to correct itself? What was it using to correct itself? The existing VE table? Also why bother doing this if you're going to put the vehicle back into MAF mode? Great stuff. Would consider buying a series that covers foundational knowledge more in depth.
No, I put it in speed density and use an error graph to determine how far the table is off. It's more important on Gen V vehicles because the VE table is part of the torque calculations
I'm tuning in an older GM PCM for a supercharged 3800 build. Most of your Gen 3 stuff has been easy enough for me to translate and use for tuning. I've been able to go through and get the MAF tuning figured out and dialed in nicely. The 3800 pretty much solely uses MAF for fueling. But I'm getting the ve table tuned, I'm curious on how important it is to fail the MAF? I don't have the parameters to just be able to fail it. Turning off the sel reporting and unplugging the MAF sensor is pretty much the only way I can think of. But if it's not that important, let me know. This system wouldn't use ve for any wot pulls, but it does need to be dialed in closer. Thanks for any advice. You've been very helpful.
Do you ever have issues with larger cams creating a false lean at idle? Ive got a car that wants to add 20% even if i run it pig rich. I wasnt sure if maybe the overlap could be sending to much oxigen to the sensor at idle causing it to read lean. Great videos i just hit the subscribe.
@@GoatRopeGarageI should have spesified its on 1 bar SD OS thats why i was wondering about false lean from the o2 causing an issue. I did catch your more recent video for idle tuning so ill apply that stuff over. I missed a few steps you layed out well. Def more comp tables to look for than the standalone and import tuning im used to lol
I have a remote tune full throttle is good but idle and cruse is rich -25 on the stft and 0 on the ltft followed the steps but car wont idle right down low lots off surge
I'm trying to tune my 2010 5.3 with stage 2 cam. I started at 18degree timing now I'm up to 33 degrees. Increments of 2. Truck is stubborn on startup and lack of power. Need suggestions
I think I am probably overthinking this, but if i am just doing a simple on a headers only car. I shouldnt have to tune the MAF or the VE tables, probably just fueling and timing correct?
Is it true that with a speed density tune I can increase my boost level with no worries and no new tune. 2000 Silverado MAF delete, headers, D1SC W/ 3.48” pulley. Want to go to a 3” pulley. 4700RPM max. Running about 7 lbs now.
Quick Question My Fuel Injectors Died On Me I Have RC 550cc Fuel Injectors That Broke I Have A Garret Turbo And I Replaced The Fuel Injectors With The Same RC 550cc Fuel Injectors And It's Running Rich Do I Need To Make It More Rich Before Tuning It Or Should I Lean It Out It's Running 14.8-14.5 AFR I'm Trying To Make It Lean So It's Not Running And Idling Rough
Hey I am getting info before I start have a gen4 truck have truck cam and couple bolt on but had it dyno turned if they tuned it with efi will I have to go back to stock and start over
@@GoatRopeGarage thank u for the response they did decent but I wasn't satisfied with it but I am a little particular when it comes to my truck but I am going to join u learned alot off ur video and haven't received my unit yet but really appreciate ur time
Do you have a video covering issues like throttle tip in? I have a gen3 olsd setup with cable throttle and going wot from idle the 90 and 100kpa cells from 800-1600rpm go way lean then the eq ratio catches up and all is well. I know just upping the VE in those cells isn't the correct thing to do as I'll have a ridiculous fuel spike on the graph in that area because I already tried that. Searched for a tip in section in my tune and couldn't find anything.
When tuning the vve you use the scanner to calculate the percent that lambda is off via your wideband. I assume you are referring to the lambda value that the ecm is commanding. Where does the ecm get the commanded lambda from? Is there a table, or is it just assuming stoich and adjusting based on other tables?
I cant get my STFTs to disable for VE tuning. DFCO turned off MAF unplugged and failed. STFTs start showing up. Set readyness to -2000mv. What am I missing. Its a Gen 5 Denali.
awesome videos!! 1 question. Was power enrichment still enabled in this? There was another video I watched that said while tuning the ve table, stay out of power enrichment.
PE was still enabled, PE will adjust your commanded EQ or AFR so you are better off keeping it enabled that way you're safe when ripping those WoT pulls!
Without PE enabled, you could run into an issue like mine, where the stock tables were off almost 30%, lean. The PE tables kept me in a kinda safe zone, at least safe enough for me to watch the a/f and pull out before blowing up.
Love your vids. I'm a complete novice to tuning. Had hpvi2 for 2 weeks now. Just been getting use to the scanner side. But as soon as my broad band comes in I'll be ready to get my feet wet. Where would you start, and what restrictions would you turn off. To just feel a little more power on an 04 Chevy 2500 6.0L (stock for now) and an 07 Saturn Outlook 3.6 (Stock) or should I even bother? Please help!

Thank you for all of your wisdom and willingness to show us your knowledge. Looking for a good baseline, on how long on average should it take to time a car from start to finish.
Depends on how much work was done, bolt on cars can be done in a day or two, more extensive can take awhile. Also depends on your level of perfect lol
Alright thank you.
Because of your videos, I am doing my own tuning now. This is the first time tuning VVE and this video was imperative to my progress. The only question I have is some cells are showing negative and some cells are showing positive. The cells that are showing a positive number are the cells that have not been populated previously. Is this normal?
When I switch from a one bar to a three bar map sensor, a lot of the data at the bottom of the graph was a negative number. I went and populated the areas where I'm operating with some numbers and it seems to be working better. Currently I'm able to get up to about 5,100 RPMs before I start getting the fuel cut off but as I build the cells it is getting better and better. You are right, you do have to do this a lot.
EXCEPTIONAL VIDEO - I've been looking and hoping for ages a good tuning channel would emerge and SD is my focus area at the moment. I am still in the learning phase but can log pretty well and know what needs changes "but its how to make the changes where I needed help"...... In my scenario I know that my tune is SPOT ON except when I am WOT I am running very rich 10.5 ... High 9's. So I am working to figure lean out that area of my VE fuel tables. I think with your videos it will help me a great deal.
Let me know if you have any questions as you get more into it or if you need certain things addressed. Trying to create a repository of information for people to reference so it will be ever evolving.
Would be neat to have a winter tune and summer SD tune in areas that have crazy weather (Texas). Probably good to run dynamic though in areas with quick weather changes, right? Texas can be 80F one day and 30F the next.
Hey enjoy the videos I don’t know if you know this but in the compare files if you go to differences and put 0 in it will put it back to normal so you don’t have to keep switching back and forth. After you’re finishing tuning
Yeah, old habits die hard
Glad I found your channel
Brought up 2 questions for me: 1.) In your logging you had to create a graph that matched the VE table. Seems that’s a pretty important table why would HP Tuners not already have that as something to choose from in loggingsince it’s so important? Why’d you have to make it manually? 2.) After your scan you copied and pasted and did multiply percentage by half. Why? Why not multiply by full amount? Pick any cell from your scan. What does the value in that cell mean and what is being read to come up with the value? I mean how did it know you were 11% lean when you first fired it up? Is it showing how car off you were from what was in the table in the tune? And after your pasted value is in that table what did it change? So finish this sentence: Now that the value here’s has changed to this, it will cause ______________ to happen thus making the tune better. Thx
Alright... Your giving out decent info and laying it out in a way a normal person can understand. Probably the best i seen. So props man. Even if i hate your prejudice against afr lol Keep bringing the content
BUT... i havent tuned any gen 5... but anything else i have tuned... Speed density tuning should be done before maf!! Anything you do on maf will need to be redone if you change the VE table.
Few pointers for viewers. You' ll run into odd stuff that will make you nearly lose your mind.
With some of the "newer" gm vehicles (07+), when there is a airflow related DTC, your transmission will default to max line pressure. You will need to disable this in the trans tune. It will blow rubber tranny cooler lines lol ask me how i know. Older stuff like the p59 dont really have this probelm
Had a e38 that would not idle with the maf failed. Nobody on the efilive side heard of the issue. But found a table described as "Maximum effective throttle area of the ETC in square millimeters with DTC" table had something like 60 in it where its related table (minus the DTC part) was 6500. put 6500 in the other table and boom problem gone and i can tune the VE.
Stuff like this will drive you mad. And it usually takes lots of searches on the forums and time browsing the tables. Little trial and error. Move slow and dont change a bunch of things at a time or you'll end up starting from square one a lot. Learning on a close to stock engine first helps. Big cam/heads can get a bit tricky for your first go lol
Both are tuned independently, when you do MAF you're disabling SD and vice versa, so as long as you're doing it correctly it doesn't matter what order you do it in. I suggest MAF first because you can get a vehicle up and running on a MAF only tune in about 30 minutes where as a SD tune can take days to dial in with street tuning.
It may be that EFI Live doesn't give you a proper way of disabling dynamic airflow, which in that case you would need to do SD first but that isn't an issue with HP Tuners.
These videos are great. I've been tuning for years, and still learn a little from each. Sure do wish HPT would automatically disconnect the scanner when you try to write a tune though. Catches me every time too.
Seriously! I do it constantly!
@@GoatRopeGarage SAME
When do you smooth compared to interpolate. Looks like you smoothed in the first few and then switched over.
I'm getting older!! 😂 Thank you so much for recognizing those of us who are actually older already and still wanting to learn!! 😉👍
Great video. Need to watch some of your transmission Tuning
Really really great stuff, thanks for putting in the effort on nice screen captures with tons of relevant explanation.
Been hesitant to get hp tuners but feeling more and more confident thanks to you. If you were able to release more videos in regusrds to 4 cylinders by dodge mainly forced induction that would be awesome.
Thank you so much for putting these videos out. You're helping out a ton of people. Subscribed liked all the things i can do to support! haha.
Just want to first of thank you for your time spent to help us out with tuning our cars, or at least helping us learn the basics. This is my first attempt at tuning. My question is for my '09 G8 GT 6.0l. I dont have the option to disable O2 READINESS VOLTAGE. I just unplugged bank1 sensor1 to stop closed loop. How would you recommend getting around this in the future? Im working with MPVI2 Pro.
Do you have closed loop enable under the Engine/Fuel/Oxy Sensor tab? If so bump it way up. Might also have a drop down for LTFT enable.
Best home tuning info on the interwebs. I've noticed on my SD logging (gen 3) that under 30 kPa in the upper RPMs its always super lean. Only get into those cells with closed throttle on decel. DFCO is disabled. You ever see that?
Yeah, I normally don't worry about them as you said, with dfco on you won't be getting any fueling anyways. Thanks!
I want to start by saying that these videos have helped me understand HP Tuners when others couldn’t. Thank you.
I’m hoping someone can help me. I have 2.2 auto supercharged cobalt and at 47%+ throttle I hit “2step” at 3700-4000rpm every time. If I go WOT no issues in that range, as long as I’m not in the 2 step mode. Before I was supercharged there was no issues whatsoever with the car.
I feel that I should add that I can build max boost while in this 2 step mode. Also it won’t do it in the first two gears. Can’t say anything about third because it shifts to fourth right before this.
Any insight will be appreciated as I’ve been battling this for months
aaaawesome explaining!
Without having someone making videos like yours.. how in the heck does someone figure all this crap out!? I feel like that old TV show "Greatest American Hero" where he finds a suit that gives him super powers, but he lost the user manual and is just trying to figure it out via trial and error. Thanks for the vids.. I'm going to go take some ibuprofen now..
Haha, dude, trust me I have felt that way, but as you go through the steps it starts making sense
Thanks for the great information and tips, its really been helpful, keep it up.
Thanks, will do!
Awesome video man!
thank you for the video and for asking for our feedback and questions, so I realize we disabled Closed Loop, but we did not disable the LTFTs and STFTs and I see guys in other videos do it in addition to disabling Closed Loop, is that unnecessary?
It's a double redundant thing, nothing wrong with doing it but it most situations once you disable closed loop the LTFTs go to zero. Log them and see, if they don't when you've disabled closed loop go ahead and disable LTFT too.
@@GoatRopeGarage I really appreciate you taking the time to respond, thank you so much, keep in mind I am never questioning your experience just asking to learn.
Awesome! Your channel is going to blow up
lots of info to take in, im on ecmlink for dsm, on speed density, wish i knew about your channel before sending my car off to english racing lol,. im still trying to learn all this tuning. im mechanically inclined but tuning stuff is on another level..hopefully in the future ill be able to mess with a more cheaply built engine,,
Your videos are great! I know you said you use to tune Subaru's do you have a video tutorials on them or suggestions to learn to tune them.
Love the videos, exactly what im looking for. Very much appreciated! I see you're a disc golfer too, that's awesome
What gen is this? Have a 14 Camaro SS LS3. It took me a minute to figure out My VE table row axis uses MAP kPa and not pressure ratio. I deleted the Pressure Ratio Math and modified the Graph row axis to MAP kPa. Now it logs. It helped me to add a chart row with EQ Cmd, EQ, and MAP kPa to monitor the variance.
I've been binge watching these videos in preparation for a project I plan to be working on, 5.3L swap in a 2nd gen camaro, they've been very informative.
One question I have regarding speed density tuning with HP Tuners like you are: Is it necessary to keep the MAF sensor when doing speed density tuning? A project I got running recently I used a holley terminator x for a twin turbo 4.8L (2.5 bar Map sensor and IAT sensor in the engine harness). I was hoping to be able to tune the stock ecu I'm using for this next project (5.3, 2nd gen camaro) with speed density since I'm somewhat familiar with it already.
It looks to me like I'd be able to break out the 2 IAT wires (signal/gnd) from the MAF sensor and run it to an IAT sensor. For the MAP sensor, according to the lt1swap website for a 2004 4.8/5.3/6.0, the pcm has a low and 5v reference already with no wire pinned to the MAP signal. Can I just run the MAP sensor signal wire to this pin on the PCM to have a functioning MAP + IAT sensor setup to setup a speed density tune?
Thanks for any feedback , if not, I'm sure I'll get it figured out as I watch more videos/read more forum posts. Thanks!
If you have a 5 wire MAF and want to go MAFless, can't you simply force the MAF to error out via a DTC. Wouldn't the IAT sensor still function with the 5 wire connection plugged in ? Early in the video there was mention of needing a separate IAT sensor and break out harness ?
Very nice video. Thanks for taking the time to get into so much depth and detail. I’m trying to SD tune the VVE table on a E67 controller. I am running into issues though by hitting reduced power mode. Any tips or tricks to not enable RP mode?
Awesome videos , great at explaining clearly on how to tune.
I have one issue that I need to share.
My car is manual.
Everytime I about to slow down, e.g., from 2000revs and when it hits roughly 1200revs, my car go lean , AFR gauge from normal to over 20 then no reading. It only does it at low rev slowing down on the same gear.
Can anyone be able to help me where to tune this area
Really like these videos man! Also Dynamic Discs and Lat64 represent! DD is in my hometown Emporia Kansas, come throw the Glass Blown Open!
So I’ve got a 2003 Silverado and trying to figure out which tables to use to disable fuel cut off.
Great video !
My question is the when you go into the ve table you have the light red blocks and the full colored blocks. Are the light blocks (transparent) the blocks you collected data on and the color ones is data you didn’t? Or is it showing you the massive difference
If you wanted to leave the car running the VE table in open loop only, with no MAF at all; what's the best way to get that set up in HP Tuners?
Any chance you can do some turbo tuning, boost tuning with pump gas and meth? I've read you can do things with timing to help spool the turbo and help load converter. Great videos, thank you!!!
The standard tuning process is the same, I am going to have a video coming out soon about tuning with the addition of meth injection as I am about to double my injection rate. It is pretty straight forward though, you still do what you would normally do on the MAF and SD tunes, you just need to take it slow and as you start working into your meth ramp in you'll run rich which gives you an area to start pulling your fuel out if need be. As far as the second thing, you can do some things on timing to help build boost off the line but I'm not sure how friendly it is on your motor. Probably something I would steer away from unless on a purpose built race car.
Thanks for your videos. I'm just getting into the tuning with a Holley Sniper on a 85 K10 350. Did you ever do any videos with the Sniper? Would love to get your input and expertise on it.
Second question since you answered my first one, show's the channel is not abandoned. Guys also disable Traction Control, can you comment on that and why you didn't?, we are talking about Gen III GM Vortec engines, 4.8, 5.3, 6.0 etc. 1999-2007 does Traction Control impact fuel/air delivery or does it not, also they do it under both Engine and Transmission tabs in HP Tuners. Thank you in advance.
On Gen III platforms your traction control is spark based, shouldn't really get into it when tuning fueling. Later generations can pull power through ETC but that's not going to change anything from an airflow tuning perspective, if it pinched back to control traction it's just going to shift the area if the map you're in accordingly.
I’m confused by the step when you multiply the tune by the values from your scan. I understand they are percentages, but why does pasting special-multiply actually end up adding the percent to the cell’s value. It’s like it actually multiplied the cell by 105% (which is what you want), for example, rather than multiplying by 5%.
When you use multiply by percentage it effectively coverts it to a decimal, so 5 becomes 1.05 and -5 becomes .95
Hey your videos are awesome and I played like three times each to assimilate all your info but, How do you connect the wideband to be read? Also if I follow all your steps very careful , it is probably to blow a motor? Hahaha and an universal question all the tunings followed exact as you shown can be applied to different car brands that hptunners allow (Nissan, ford,dodge)? Sorry for a lot of questions I know you are very expert😎 and I'll be very grateful if you answer me, good vibes!
awesome bro love the video thanks for the knowledge I've been learning so much thanks again
great videos, you have saved me so much time! I was able to log my AEM thru the serial by watching your video and a million other tricks. On this video I have one area I don't understand. In high load rpm if you use the lambda and multiply the base map you are pushing towards 1 lambda which I understand for cruising, but you would want approximately 0.85 in high load rpm situation?? I understand not wanting to disable power enrich but that is effecting your wide band readings which when you multiple will drive the overall ratio to 1 versus .85 is high load. What am I missing?
Leave PE as it is, you're commanded will adjust appropriately and so your error graph will work
Thank you for the video we learned a lot. I just want to ask you why are you dividing the data by have before applying? I guess this delaying the process. The software should suggest the corrections without the need to modify the numbers based on the AFR reading. Can you explain why are you dividing by 2? Thanks
Just got HP tuners and I'm going through your tuning series. Definitely been over the speed density video a lot haha. I have a 13 Explorer EcoBoost I just put stage 3 turbos on but this thing has six speed density maps ???? Is this a case where I'd be tuning all these SD tables?
Great video, I couldn’t find your maf video
Uploading the new version of it right now. Should be up by tomorrow.
Chris, the MAF video is up now: th-cam.com/video/7IoWmLEmlvE/w-d-xo.html
Thanks!
Goat Rope Garage thank you I’ll give it a watch now
Great videos! Thanks... I am new to tuning... want to tune my 95 Lingenfelter Suburban with a 605. Do you ever use TunerProRT? I dont think HP will work with my truck.
Hi just wanted to let you know thank you for sharing your knowledge it's teaching me alot I am stuck with my turbo Camaro on e85 my afr at idle is at 10.9 to 11 I know that's rich and when I drive the car and floor it it goes to 16 and sometimes 15 afr is that bad
Yeah, that's dangerous lean, be careful
I tried to start sd tuning. It’s super rich and went into limp mode when I drove it. Did I miss something? E67 gen iv. Thanks for everything you do for us!
Look at your AFR to start, you can pull some fueling out of need be. What's your year/platform and mods?
2008 envoy Denali. Long tubes big cam 10.5 :1 comp. 6.0 e67 ecu
In the “sweet spot” of my graph it’s 100.39. I assuming that that the max
@@michaelbrakeall2267 100.39 on your error graph? Doesn't make sense, you sure you've got your graph setup correctly?
Probably not lol. Should I be on average?
So when you're logging, the values populating the cells are the % error from a proper air/fuel ratio, negative values being rich, and positive values being lean, right?
This is awesome. Just a suggestion - couldyou do a vid that runs through the tables for air, fuel and spark? Not how to tune them, just a few sentences on what the main tables do and when they are used. It would be a supplemental 1.1 intro vid. Just a suggestion. These videos are great.
I'll add it to the list!
Wow, great content! Looking for some context though. Seems as if you manually put the ECU into speed density mode, ran the car around, and relied on the ECU to correct itself? What was it using to correct itself? The existing VE table? Also why bother doing this if you're going to put the vehicle back into MAF mode?
Great stuff. Would consider buying a series that covers foundational knowledge more in depth.
No, I put it in speed density and use an error graph to determine how far the table is off. It's more important on Gen V vehicles because the VE table is part of the torque calculations
I'm tuning in an older GM PCM for a supercharged 3800 build. Most of your Gen 3 stuff has been easy enough for me to translate and use for tuning. I've been able to go through and get the MAF tuning figured out and dialed in nicely. The 3800 pretty much solely uses MAF for fueling. But I'm getting the ve table tuned, I'm curious on how important it is to fail the MAF? I don't have the parameters to just be able to fail it. Turning off the sel reporting and unplugging the MAF sensor is pretty much the only way I can think of. But if it's not that important, let me know. This system wouldn't use ve for any wot pulls, but it does need to be dialed in closer. Thanks for any advice. You've been very helpful.
Do you have any videos on h and s mini max? Looking to tune my own 6.4 diesel
Do you ever have issues with larger cams creating a false lean at idle? Ive got a car that wants to add 20% even if i run it pig rich. I wasnt sure if maybe the overlap could be sending to much oxigen to the sensor at idle causing it to read lean. Great videos i just hit the subscribe.
Disable the MAF and see if it still does it. If you have a ton of overlap it can mess with the MAF sensor like that.
@@GoatRopeGarageI should have spesified its on 1 bar SD OS thats why i was wondering about false lean from the o2 causing an issue. I did catch your more recent video for idle tuning so ill apply that stuff over. I missed a few steps you layed out well. Def more comp tables to look for than the standalone and import tuning im used to lol
Follow up and let me know if you are still having issues after
How do I find or calculate manifold volume? I have a 6.2 manifold on a 5.3 truck
I have a remote tune full throttle is good but idle and cruse is rich -25 on the stft and 0 on the ltft followed the steps but car wont idle right down low lots off surge
I'm trying to tune my 2010 5.3 with stage 2 cam. I started at 18degree timing now I'm up to 33 degrees. Increments of 2. Truck is stubborn on startup and lack of power. Need suggestions
I've set up the speed density table exactly step for step in this video and it's still not populating any data in the graph. What am I doing wrong?
I think I am probably overthinking this, but if i am just doing a simple on a headers only car. I shouldnt have to tune the MAF or the VE tables, probably just fueling and timing correct?
Is it true that with a speed density tune I can increase my boost level with no worries and no new tune. 2000 Silverado MAF delete, headers, D1SC W/ 3.48” pulley. Want to go to a 3” pulley. 4700RPM max. Running about 7 lbs now.
In MAF (3) he disabled DFCO by setting very high rpms, and in this video he uses a high rpm for enable and 1 rpm for disable. Are both methods valid?
How do you set up the histogram for gen3 engines ? Map is in kpa
Can You show us HP tunners settings for MAP sensors ? Regards from Poland :)
Quick Question My Fuel Injectors Died On Me I Have RC 550cc Fuel Injectors That Broke I Have A Garret Turbo And I Replaced The Fuel Injectors With The Same RC 550cc Fuel Injectors And It's Running Rich Do I Need To Make It More Rich Before Tuning It Or Should I Lean It Out It's Running 14.8-14.5 AFR I'm Trying To Make It Lean So It's Not Running And Idling Rough
What do I do when my car doesn’t have a maf sensor, the Jeep tj 2005 doesn’t come with a maf sensor, only a map sensor. How would open loop work?
Hey I am getting info before I start have a gen4 truck have truck cam and couple bolt on but had it dyno turned if they tuned it with efi will I have to go back to stock and start over
Depends if the locked it, if not you should be fine. There might be a few small tables that don't carry over but you shouldn't need them.
@@GoatRopeGarage thank u for the response they did decent but I wasn't satisfied with it but I am a little particular when it comes to my truck but I am going to join u learned alot off ur video and haven't received my unit yet but really appreciate ur time
Do you have a video covering issues like throttle tip in? I have a gen3 olsd setup with cable throttle and going wot from idle the 90 and 100kpa cells from 800-1600rpm go way lean then the eq ratio catches up and all is well. I know just upping the VE in those cells isn't the correct thing to do as I'll have a ridiculous fuel spike on the graph in that area because I already tried that. Searched for a tip in section in my tune and couldn't find anything.
Do I skip this step if I’m not planning to run without a MAF sensor? I’m NA mild cam 10.4:1
When tuning the vve you use the scanner to calculate the percent that lambda is off via your wideband. I assume you are referring to the lambda value that the ecm is commanding. Where does the ecm get the commanded lambda from? Is there a table, or is it just assuming stoich and adjusting based on other tables?
Yep, it's looking at stoich and then bringing in the other tables to make any appropriate adjustments.
How do you decide when to smooth vertical or horizontal?
I cant get my STFTs to disable for VE tuning. DFCO turned off MAF unplugged and failed.
STFTs start showing up. Set readyness to -2000mv.
What am I missing. Its a Gen 5 Denali.
Some gen 5's it won't work, use the special features on the scanner, you can turn them off there, just have to do it every log.
awesome videos!! 1 question. Was power enrichment still enabled in this? There was another video I watched that said while tuning the ve table, stay out of power enrichment.
PE was still enabled, PE will adjust your commanded EQ or AFR so you are better off keeping it enabled that way you're safe when ripping those WoT pulls!
Without PE enabled, you could run into an issue like mine, where the stock tables were off almost 30%, lean. The PE tables kept me in a kinda safe zone, at least safe enough for me to watch the a/f and pull out before blowing up.
Love your vids. I'm a complete novice to tuning. Had hpvi2 for 2 weeks now. Just been getting use to the scanner side. But as soon as my broad band comes in I'll be ready to get my feet wet. Where would you start, and what restrictions would you turn off. To just feel a little more power on an 04 Chevy 2500 6.0L (stock for now) and an 07 Saturn Outlook 3.6 (Stock) or should I even bother? Please help!
Odd and off topic to this, if I want to get rid of my cats how do I get rid of the monitoring for the post cat oxy sens?
