With each video I'm getting closer and closer to having everything dialed in correctly. Come quite away from just adding some timing and removing torque management, lol.

Thanks for these videos, I have a 2015 Camaro Z28 with Gen 4 ecm, 427, exactly what I needed. Appreciate your straight forward common sense of tuning!

Heads up, on a 2012 Yukon xl I had to use the manifold switch open in order for the VE table to make any difference in afr. Thanks for the videos!

@mesaman3000 3 года назад

Hey, Thanks for all these videos!! I have recently completed my MAF tuning with a lot of help from you! I did a DOD delete and cam swap after I had a Cyl #2 lifter fail. My 2013 Silverado has the Open and Closed tables with different values. Did you ever make a video showing how to edit these separately? I have watched maybe 1/3 of your videos, but I haven't seen anything on this topic yet. I have also done general searches with no luck yet.... Thank you again!!!

One of few channels that being a Patreon pays off. For you guys on the fence, you get a direct email when your a patreon and every time I have needed help on my tune he has replied very quickly. Not many places you can get that for 15 a month. Love this channel!!!

@larryshuckjr7994 Год назад

Why would I pay 200 bucks a year for someone that doesn't even explain the whole process. I think he leaves shit out on purpose. I'd just as soon. Have someone like Gwantney remote my tune. How could I trust this dipshit.

@thekingscene 3 месяца назад

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

@GoatRopeGarage 3 месяца назад

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

@Busa0069 Год назад

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.

@chadh6759 2 месяца назад

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?

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.

@tinarausch354 Год назад

well mine looks a lot different it is for a 2011 CTSV 6 speed manual.

Take a look at a 09 CTS V if you get a chance. I believe it has all the GENIV options with some GENV. So many options it is overwhelming.

@lety2467 Год назад

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 Год назад

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.

@cramstick 2 года назад

I set up the EQ Err graph but it does not populate the graph while logging, but I can see the cells hit when viewing the log. The speed density graph is the same way, it was already on the scanner when I started using it.

@FrostE941 Год назад

Same 🤷‍♂️

Ever time I add a graph the way you say it does populate data. all the other stock graphs do, but nothing in the new chart

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 5 лет назад

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

@biffrollins6317 5 лет назад

If you have the compare open with the differance highlighted and you make the reading zero it will make the change for you.

@pajalanpaja Месяц назад

Hi. This is propably a stupid question but do i need to accelerate all the time when logging or do i have to do some functions so it wont log when decelerating etc?

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)

Correct, calculate then copy and paste!

On my 15 camaro on the virtual ve table, manifold switch closed is all zeros. Manifold switch open is filled out like the one in this video. Why is that?

Cars without manifold runner control switch use the Manifold Switch Open table. Goat rope gets this wrong on multiple videos, BUT he makes all tables the same so no matter.

So, on my Gen 4 I am not using my wideband, do I need to disable PE in order to tune with the STFT+LTFT [Math] graph?

You can, but doing so you run the risk if causing damage, I'd pull some timing out to be safe. I'd install a wideband to be safer, lol

@benjames6270 5 лет назад

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 5 лет назад

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.

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.

@randyzehnder9263 2 года назад

hey, I'm not sure if you are still active on this, but any way I followed everything according to how you set it up on the video and I cannot get the scanner to fill in the graph as I'm logging. the blue goes around and highlights the boxes but doesn't put any values in them. any info on this? I'm working with a 08 trailblazer with a vortec 4200 inline 6 i think it has the e67 ecm in there if that helps

@leroyhart1368 10 месяцев назад

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 😆
