    might wanna try logging commanded afr next time too nino lol

    I still say your VE table is just too jacked up at this point to make much sense of things.

    Just looking at your STFT you can see your nearly 40% overfueled in some areas.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    I agree, just do some good long logs of your AFR Error % and slowly but surely it should come back in line....
