    Default Can anyone see anything wrong here???

    I'm just about ready to pull my hair out.
    Truck is bucking...again...still.
    I have a feeling it's too rich and that 'MAY' be causing it but I'm not 100% sure.
    I also can't see where AFR's in the 10's are coming from.
    I've also attached the log and tune this screen shot came from if anyone could take a peek and maybe...just maybe someone can see something I can't?
    In this tune....although I had the VE tables pretty well worked out...I decided to lean off the main VE table a little but maybe I should try leaning the boost VE table out a little.



    Thanks

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    only thing that i can see that would be telling it to go into the 10's for AFR is {B3603}Commanded fuel when in engine protection. Maybe try changing from 1600rpm up to 6000rpm to around 11.9AFR. Other than that there is nothing else telling it to go into the 10's AFR.

    Thanks,
    I just changed that and I'll see what diff it makes. I'm not holding my breath. Lol!
    If anything I'd think I'm running too cold?
