    OP, it doesn't really matter in the whole scheme of things because you can't exchange older and newer OS's in the ECM anyway, you are somewhat stuck with what GM had at the time.

    I don't remember any specifics either aside from I know the anti-theft alarms in the HSV's were problematic at the best of times.

    Well you never mentioned what vehicle type or controller you were dealing with, makes it hard to offer advice. :music_whistling_1:

    You're looking in the wrong place, EFILive software does not allow users to create delete tunes.

    It tells you everything you need to know, to save you the trouble here it is.

    V2 RJ-45

    2 - CAN + (H)
    3 - CAN - (L)
    4 - GND

    Well first thing you need to understand is if there is an issue with that modified tune then the ECM will just brick again once you recover it and flash that tune back in, so maybe not use it until...

    $0549 usually does mean the tune you've put in has caused the ECM to brick, they can be recovered but you have to force the ECM to bootmode. Given you have the bench force set up you can ask them to...

    The patch is done for that OS, you do need to have your V2 plugged in to the USB port to see it.

    That error would probably only come back if the ECM is not running an EFILive CSP5 OS, EDA is part of that upgrade.

    EFILive does not give users the ability to create delete tunes, the tune must have been created outside EFILive and just flashed in to the vehicle.

    Problem is we can't patch the OS to get around the VAT's because it is digitally signed so unless the OS code is 100% standard the ECM won't accept the changes, cal flash only.
    But what I don't know...

    I think you REALLY need to contact the company that makes the bypass kit for guidance, the OBD-II port needs 12V.
