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.

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

Goat Rope Garage- THANK YOU SIR! Will do you seem very knowledgeable!

[@c4love]

@@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.

[@GoatRopeGarage]

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.

[@c4love]

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?

[@larrygregory1795]

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.

[@christopherlloyd6013]

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.

[@garydeanstovall370]

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!

[@speedycpu]

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.

[@jamesrossmotors]

Awesome content on all your videos. I have a question I hope you can answer. Does PE effect the VE table when logging and pasting over? I have read before that PE should be disabled when setting base fueling or are the cells in the upper RPM a calculation of both base and PE? I have never seen you enable or disable PE

[@franciscoparga2863]

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!

[@boosted0079]

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.

[@nalshuaibi160]

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

[@nsboost]

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

[@GoatRopeGarage]

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.

[@DandersonGM]

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

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?

[@frankyhernandez476]

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.

[@GoatRopeGarage]

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

[@frankyhernandez476]

Alright thank you.

[@DemonChild]

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

[@zero2583]

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.

[@brettstoner8283]

What are your thoughts on using the NB fuel trims to dial in the SD tune under 4K instead of the WB?

[@joshuanobody]

Hey how did you make that EQ gauge in your scanner? Thanks

[@wesgates5632]

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?

[@GoatRopeGarage]

Yeah, I normally don't worry about them as you said, with dfco on you won't be getting any fueling anyways. Thanks!

[@J2daK]

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.

[@GoatRopeGarage]

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.

[@kylemilford1769]

I have an 03 5.3 out of a silverado i swapped into my S10. Didnt even realize these use MAF and IAT been running without it for 6 months, Fuel trims are perfect, should I change something in my OS to stop the ECU trying to use a maf? Or is it fine as it is

[@GnarlyBlade]

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!

[@Good-Enuff-Garage]

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?

[@GoatRopeGarage]

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.

[@Good-Enuff-Garage]

@@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.

[@DarkKnight-ix2pw]

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

[@hannahhill1386]

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?

[@GoatRopeGarage]

Leave PE as it is, you're commanded will adjust appropriately and so your error graph will work

Hey man nice vids! Quick question, I’m tuning vve on my 2017 Camaro ss. The only mods are cat delete and ported throttle body. I’m comparing my tune map against my stock map and I’m seeing as much as 20% fuel removed in spots and 10% added. Does that seem normal?

[@GoatRopeGarage]

Yeah, you have to remember that the factory tune is a one size fits all kind of ordeal and do you can see quite a bit of fuel removed from a completely stock car. Where you're adding fuel is where you've interested airflow with your mods.

[@THEmadmikeismad]

How close are you trying to get the map/ve tables? I've done 20 runs/logs now, and can't keep it consistent. I'll change an area 2%, run again and that cell will be 20% off. I adjust it 10%, and then it'll be off 2%. I've started adjusting the adjacent cells on the outside edges/unreached areas of the map, but sometimes that will make the whole tune lean out 20-30%. And heaven forbid the temp changes 5* between runs lol. I think I'm going to have to settle for getting it mostly within 10%, towards the rich side. It'll still be better than the stock map, which was off almost 30% across the board, towards lean.

[@evltwins]

Hey Goat Rope, I've been enjoying your videos while working from home. I'm one of the pre-2008 guys and started reading up on tuning back in 2007 for my '06 GTO. One of the things that was preached when filling up your histograms was the importance of steady state measurements. I've watched a few of your videos and this was the first one I heard you mention smooth throttle changes but I haven't heard much emphasis on it. What are you thoughts on trying to stay in one cell for a few seconds while driving to build a steady state reading and reduce any fuel multipliers, like accel enrich, from affecting the readings?

[@GoatRopeGarage]

It's always a good practice and that it's why we filter cell hits to make sure we have good data on each cell. The other stuff isn't important if you're using a wideband as they will be reflected in the commanded AFR or EQ

[@pandora1875]

Is it worth it to get the pro features with the MPVI2 to tune a Gen V in a 73 Nova?

[@smokecreekstudio7320]

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

Yeah, check your VE table, your standard table is based on your RPM as the columns and MAP as the rows, well, your stock ECM has a 1 bar sensor, since you switched over to a 3 bar OS you need to check your VE table and make sure it has been rescaled and has fueling information in the lower pressure area (Idle area). If you still have issues keep closed loop enabled and look at your LTFT tables in the scanner, they are going to be WAY off. You will need to create a new histogram based on your 3 bar OS. Just copy the rows and columns over that way you are working one to one from your histogram to the VE table. Once you get the fueling close enough to get out of closed loop and into open loop tuning then start dialing the fueling in from there nice and slowly. You will use your LTFT trims the same way you would use your EQ Error table, but you can probably use the "Mulitply option" instead of multiplying by half to dial it in faster. If you need help let me know.

Does it use credits every single time you did the rewrite or how does that work with hpt ?

[@jaywalkin8205]

How do you set up the histogram for gen3 engines ? Map is in kpa

[@erickalmaraz6837]

Correct me if I'm wrong, since I'm still using MAF, do I just need to tune lower end of VE table since computer uses that when launching till Maf takes over?

[@alexholt5524]

Hey Goat Rope, great stuff got a question at 26:02 the EQ gauge goes to 9.99 which appears to be cell 0.3 @1600 rpm which while not clear appears to be 59 so changing the VE table by 59%. Is that a fuel cut for a gear change or something and why it goes so lean and how does that affect your tuning?

[@GoatRopeGarage]

Always look for bad data like that and interpolate over it to even it back out, generally you will have one or two cells that get a bad reading for some reason or another, so it's always a good idea to look at your histogram.

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!!!

[@GoatRopeGarage]

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.

[@JakeM624]

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?

[@dobermanracing]

How do you decide when to smooth vertical or horizontal?

[@datrumakboy1020]

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?

[@anthonycurfman5155]

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

[@Mr_SynergyPerformance]

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..

[@GoatRopeGarage]

Haha, dude, trust me I have felt that way, but as you go through the steps it starts making sense

[@scriptmike]

I'm having trouble with SD tuning. working with a cruze 1.4 turbo, E78 controller. she has VVT. would I need to disable vvt to get it dialed in or am I missing something?

[@JohnJohnson-vw6xb]

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.

[@GoatRopeGarage]

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!

[@THEmadmikeismad]

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.

[@hannahhill1386]

By the way I am tuning a 99 dodge 410 stoker. The fuel table is injector pulse width versus map but the process would be the same, correct ?

[@makdaiss]

Can You show us HP tunners settings for MAP sensors ? Regards from Poland :)

[@general23cmp]

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%.

[@GoatRopeGarage]

When you use multiply by percentage it effectively coverts it to a decimal, so 5 becomes 1.05 and -5 becomes .95

[@hassanabas1549]

What if I am running with maf op and I want to adjust my ve tables for better fuel do I do the same and disable my maf or do i just use ltft in cl to calibrate the ve table?

[@mbrownz71]

Do I skip this step if I’m not planning to run without a MAF sensor? I’m NA mild cam 10.4:1

[@Anks329]

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?
