    Most new ECM's that GM are releasing (2022 onwards) are secured with a digital signature.
    The list of ECMs is pretty much the list in the new TIS import feature in the V8 tools window.

    Those ECMs can only be flashed with stock files. The stock files have been signed by GM as "OK to flash".
    Modified files have not been signed by GM so the ECM will reject them at the end of the flash.

    Regards
    Paul
