    LT5 Throttle Body Tuning e92

    I was curious if anyone had any new information about the lt5 throttle body tuning. Have the max area maps been created yet? And is torque management... reliable with it yet?
    Or if there is somewhere to find what is in the e99 ecu for the throttle body?
    Just trying to for-see if the lt5 throttle body would be a mistake over just the 87mm.
    Any info here would be fantastic.
    Thanks
    Mike

    Scaler is around 5500... but honestly I don’t even change the scalers on gen 5 ecms anymore

    You will need to edit Cranking Airflow, VVE and Virtual Torque.

    If you're installing it on a zo6 don't bother changing anything besides re scaling the MAF for the increased airflow.

    You don't have any issues with idle Spark Advance by only changing the MAF?

    Some will randomly want to idle with negative timing. No big deal to fix just decrease negative spark areas in idle zones in the virtual torque tables to bring the spark up and throttle will close down to reach torque. Definitely worth it imho.

    Nope. Even with a Katech 103 it idles perfectly fine timing n all.

    Cranking Airflow needs adjusting downwards to stop the flare up but it shouldn't be surging at all. A couple of things to try, #1) pull the negative battery terminal for 5 minutes, then reattach and crank car while cold and let warm up at idle without ever touching the accelerator pedal. #2) and this is an odd one but worked for me on a Gen 6 Camaro, I transferred the original throttle body motor over to the ported TB and the surging completely went away. No idea why this can sometimes be a fix for this but it is.

    If neither of those help, then you likely need to have Tony swap out your TB because it was over ported in the wrong(sensitive) area.

    I'd return it for another one.
