Love your vids. They’ve helped so much. I used your Gen 4 MAF video as well as this one to help tune my vette. I have a question. After tuning the MAF (I got the MAF to within 1%) and the VE (this was tricky, did about 5 logs), when I re enable dynamic airflow to run both together. The AFR under medium to light throttle bounces around a lot! From about 14.5 to 16.2 or so. Just back and forth up and down really quick. Never seems to settle in until I get on the throttle pretty good or go WOT. What do you think I could be doing wrong when I re enable dynamic airflow?

[@Straightshot75]

Thank you

I'm about to put an e67 in a Holden Commodore V6. I know for a fact, the GM HFV6 uses a manifold intake switch, and both VVE tables are different. Should make it fun to tune, with VCT too. Mine is an LY7 3.6L. Would love a follow up video.

Maybe this is something obvious but I didn't see it mentioned anywhere so I'll share what I was just fighting with. Running 2bar OS E38 and recently switched to SD after having issues with my MAF. Car idled great on MAF only but with it failed I couldn't get a good idle. It just didn't want to let in enough air. Played with all the usual idle tables until I happen to leave the cursor over percent max fail. It said if the maf map or tps fails it limits idle throttle to that amount. Maxed it out and now I can drive in public without getting embarrassed by my car stalling 😆

[@euba0149]

I have some how been logging and making changes using “percent ratio %” as my row axis ... have been making changes like this for about 2 days now and have been getting the truck running decent that way ... what is the difference in using “percent ratio %”(math) & the data right off the MAP sensor for the row axis value ? Does it work the same either way ?

[@spencerbevington4697]

what do i need to log when doing this? i cant get my graph to collect any data.

[@buggyndoc]

Great videos. Confused about copy and paste to VVE tables. If you copy and paste percent half to one table and calculate coefficient, then copy and paste that table to other table and calculate coefficient again, wont tables be different? I copied and pasted percent half to each table individually before calculating coefficient. Did find that as a newbie to HP and tuning, initially only modified closed table and that did not affect logging, so my conclusion is that my car (08 G8) works from open valve table or possibly both under different circumstances. Again, great videos and information. Thank you!!!

[@GoatRopeGarage]

Make all your edits to the one then calculate it, when you copy it over to second table you will notice that nothing changes when you calculate it because all the values are sane for the formula that calculates the coefficicents.

Hi, i'm having issues with tuning my VE table, the changes I make to the VE table don't correspond to the errors in my next datalog. The engine light does turn on for PO103 after a few seconds of the car running then the AFR on my AEM x-series jumps from 12.0 back up to 14.7ish when the engine light is on. The car is running lean under lighter throttle applications and I can't correct it. I've made all the changes listed in your video to fail the MAF. I've seen other videos they are also changing the Airflow-Dynamic-high rpm disable to 8,000rpmand re-enable to 100rpm. I have not done this for the VE -is this my issue? Thank you 2012 grand sport A6.

[@benjames6270]

I have a question about the long term fuel trims, does the computer store those even though you have effectively erased it an rewritten the tune file and also when we are doing the data logging if we have removed it's ability to trim the fuel will it use the last "stored" fuel trim as the fuel base, in turn giving you information that is out by that percentage? I don't know if I'm making sense Ben

[@GoatRopeGarage]

When you're working a config as opposed to a complete rewrite my guess is they can carry over in that situation. But they only apply when you are in closed loop so they shouldn't cause an issue. When in doubt go ahead and clear them before you start that log.

[@jc8130]

I know this is old... Why/how would a o2 sensor pull timing in open loop? I have a small header issue working through. Thank you J

[@dspdustin3364]

Thanks for making such great videos. How would you go about SD tuning on a e67 with an engine that has VVT? Park both cams at 0 degrees, adjust the 0-0 table and let the computer adjust for each angle? Also when would you change the ExhaustCam.IntakeCam table in the VVT tab for VVE coefficients? Thanks!

Gen V VVE question. Truck is 2014 L83 cam swapped with non-vvt cam. Variable camshafts set to “none” in tune. Can I tune VVE with intake and exhaust camshaft angle at 0? Or do I have to do all 20 tables?

[@garlandjones7709]

If you want those tables to match copy before calculating coefficient. Then calculate. Then paste and calculate in the 2nd. It wont match if you paste after calculating, bc the recalculation will blend it with the 75kpa and higher(using just your example)

[@GoatRopeGarage]

Correct, calculate then copy and paste!

It’s amazing how just a tiny kernel of incorrect information can bloom into a major disaster for the right person. Ive been struggling to tune my VVE and went back to basics to try and find out why my corrections are just never changing. I usually give up on tuning the VVE and run Gen4 vehicles in MAF only tune. It’s been manifold switch OPEN, all this time I’ve been doing it wrong and only pasting in manifold closed. Finally read on forums that best to change both open/closed tables.

So it has an IAT sensor on it as well, 3 bar MAP and they put in an O2 sensor on the downpipe up top because they said supposedly it would not read the other 2 O2 sensors. And yes my VVT has been deleted as well as the FPCM.

Should you leave dynamic air flow on when doing VE tuning?

So dynamic is always on, it’s the final airflow calculation, it references MAF and VE, so just fail the MAF and you’re good

How different is this if your using the IAT part of the MAF, would I still turn off the MAF, would think no. I don’t have the MAF sensor I used the wiring to make make a IaT sensor out of it.

That won't effect anything, you've already failed you're MAF

[@lety2467]

Newbie question here: Why bother tuning the VE map, or "Virtual VE" map at lower part throttle RPM's like cruise? Isn't the MAF in the drivers seat there and the VE map in those areas really doesnt matter? Thx for the insight.

[@GoatRopeGarage]

The VE tables are always effecting fuel, you can disable the MAF and run VE only, but you can't disable VE so it needs to be dialed in, specifically for transient fuel where the MAF sucks at metering air.

[@BigMatt302]

My dynamic airflow is set to disable over 100 rpm and reenable is 0. I see on the video that it is set to disable at 4000 and re enable is 3900. Do I need to switch to this? Or does failing the MAF do this automatically?

[@GoatRopeGarage]

Yep, once the MAF fails you're going to be using the VE table.

Question, you said back in the day you used to unplug MAF to make it fail...what years did that apply on?

@@jaydubb71 honestly man, it should be one of the first mods people do. They spend all this money on performance parts and get mad when they blow crap up because they don't realize they aren't running safe!

[@jaydubb71]

@@GoatRopeGarage Exactly! Agreed!

I have a 2008 silverado e38 platform. I just finished up tuning the MAF and I'm trying to tune my VVE and it is so bad the truck won't stay running what should I do to atleast get to a good starting point. I have learned a lot from your videos great content. im just at a loss right now any advice would be greatly appreciated 🙏

Do you mess with proportional table or integral delay table when you have headers?

[@GoatRopeGarage]

Usually I just try to update the switching voltage instead of messing with the speed in which it tries to make the narrowband sensors switch

@@GoatRopeGarage would it be possible to get a video of you addressing getting cats for gen 4s that get the insufficient switching o2 codes i havent found a lot of info on how people address those 🙏

The HpTuners documentation says that if your car is not equipped with a manifold switch then the default table used will be manifold switch open.

Be safe, copy and paste!

Can a person use AFR Err instead of EQ Err. In EQ Err, it wont populate in the hist for some reason?

[@GoatRopeGarage]

Yep, either will achieve the same results
