I've never had Greg tune my car, but he has offered a SHIT TON of help with tuning my own car. If I ever decided to have someone tune my car he would be at the top of my list just for the fact how...

that's exactly what I wished I would have done...lol. I put new injectors in AND removed my cats at the same time. After that is when I noticed those lean spots. And after hearing Jayrolla had...

It was L1FTD that was doing alot of testing with this and I THINK he was doing fpcm pressure testing as well. Is the LS9 you are tuning no longer have cats? After hearing that the issue was still...

Some of these tuners on this forum do this for a living so they are going to charge accordingly and probably won't be that cheap. They spend ALOT of time/effort in learning all this shit so you...

I've actually tried changing my zone boundaries to have the 2600 rpm area in the middle of a zone versus the end and still had the same exact lean issue

[QUOTE=Critter93;781655]Thanks for the offer! Don't worry about it though. If it affects the drivability down the road I will take another look but the drive home this morning was smooth as butter....

From my experience you will be better off adding fueling via the maf vs. the VVE table (assuming you are running an OEM style "blended" tune). In my experience I've added ALOT of fuel in those areas...

welcome to the party pal.....lol. I noticed this years ago with no real solution. Get your reading glasses on if you like to read all of the things that me and many others have tried. There's also...

It was some quality reading material coming from my point of view....I didn't get much work done because I was too busy reading that thread..lol. Sorry OP didn't mean to hijack, post your tune/log...

FOR REAL....especially when you give them sound advice and they decide to do the opposite...then...comeback and ask why is everything jacked up and not running correctly...lol

lol..yeah Edcmat-l1 very knowledgeable (along with others on here)...but..the best is when he tells someone his honest opinion and they get all butt hurt...lol.

NOW I feel better about this thread..lmao

considering the last comment on this thread was in 2019 you may want to start your own new thread

I'm disappointed...no crystal ball?????

Appreciate the explanations hjtrbo and 07GTS, I'll mess with my IVT table slightly to try and correct it. Thanks guys!

Doesn't if your commanded not match your actual even while cold and in OL your airflow model is off?

So are you just manipulating your OL IVT table to get there?

Yeah, I guess I have it ingrained in my brain that I want to see commanded match actual...lol. I'll revisit possibly altering my OL IVT tables

One thing I did notice was shortly after re-enabling my prediction coefficients I noticed this. I'm going to go back having them all zeroed out and see what happens because I don't remember seeing...

Hmm..never thought about doing that. Thanks for tip I'll try that out. Since it is such a short period of time I'm not too worried about trying to get it perfect, but I'd still like to get it a tad...

13.5 AFR with 9.5 lbs of boost...yeah no big deal..lol

pfftt..doesn't see it? or IGNORING it? lol.

Hey guys, just trying to tweak my cold start stuff and I noticed that I have a very lean tip in (relative to commanded) when the engine is cold. Maf and VVE are dialed in when the car was at...

In regards to changing your min map value to 85kpa, your engine is still in a vacuum condition at that point. Yes you are raising it but with your current pedal settings I can almost guarantee that...

I've always had good results with using map instead of pedal position. Especially in higher gears where a very small amount of pedal movement can result in large change in engine load. Where I have...
