    sanity check please. feel like something isnt right.

    spent a lot of time on dialing everything since my last post when i just got the car... it runs a lot better but feel something is off. but i cant seem to figure out what it is. hoping someone can look over this calibration and log for me.

    13 camaro 1LE on e85 with ethanol sensor, some kinda ford flex fuel injectors, cam and bolt ons etc...

    Without a clear description of "something is off" no one can help you. Are we looking at cold starts? Hot starts? WOT? Transmission shifting issues? TCC not staying locked? Knock? Random torque management? Idle issues?
    And also...seriously...Ford injectors in a GM? That is probably the issue right there...you don't have the correct injector data. Unless you sent them off to Greg Banish to get legit GM formatted data, it'll never be right.
    I bet 99% of your problems go away with quality injectors with quality data.

    There is perhaps a miss on the drivers side but I cannot tell for sure.

    I can convert Ford data to GM data from OEM Ford sheets but there is some extrapolation involved. Usually where bad injector data will show is in decel, near around idle, etc.

    There's actually a lot going on here.

    The injector data is off just looking at the data log at the end when it should be up to operating temp. The trims are pulling as much as -13% to move the O2s from 800mv.

    The dynamic air and MAF air both are really high at idle. Looks like the airflow model is off (duh) because the injector data is off.

    It's idling way too high.

    In a couple spots the idle over/under timing looks really weird.

    It's running too cool.

    It looks like it may have a misfire on both banks at different times. Can't say 100% because most of the time they look smooth.

    You're not logging MAP pressure. MAP pressure is pretty damn important.

    Never looked at the tune but you got work to do.

    Found a cracked insulator on one of the spark plugs. I am now getting somewhere with this thing. I?ll post a new file and log shortly.
