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...

Yes, that's correct. I've been steady state in those areas many times and they will still show up as lean

so, if you interpolate then the area between 1600 and 2600 is going to be very rich. Would you just leave it like that?

Really wish I was one of the lucky ones....lol.

going 100% SD- yes lean spot still there
turn off injector desoot mode- Mine has been off since I bought the car in 2015

It seems that it only has happened to a handful of us. However Jayrolla...

What you are experiencing is a little bit different than what I am experiencing. The fuel pressure stays relatively stable (jumps around a little bit at that 2600 rpm), but my car has never got so...

Exactly!!! Yeah, up to this point I'm ok with raping the PE table and making a few areas of my maf curve slightly richer for CL operation.

It's all good, you can put that info here if you'd like

so you are using the stock FPCM from a v2? Maybe it has something to do with the fuel rail then...
