After performing Calc.VET tuning (a few times) I feel I have an accurate VE table and the car runs very smooth. The only issue is my AFR at WOT is around 11.9-12.2 when I am asking for 12.5-12.7.
I know my MAF freq has always been a bit jumpy, especially at higher RPMs. BUT I have recently installed an airflow straightener from Halltech, didn't seem to help much.
Here is my latest log: 7.20.efi
My guess is the MAF is causing this since the PCM looks at MAF freq during WOT (right?).
Any help is appreciated. I'd really like to see what she does when it's running at optimal AFR.
