    Which ECM type is that model using?
    It is not an issue I have heard of before.

    Anything out of the ordinary with tuning it? Was it locked after tuning?

    No it was and is fine except for the code and associated light after tuning first time with EFILive.

    Have you done that specific model before?
    If you have the GM tools then maybe try a theft relearn.

    Will do that in a couple hours. Hope it will help as the BCM is setting a code saying security code not programmed in ECM. First time with this particular model but it was just a simple Calibration Flash that caused it. Even tried full flashing after to no avail.

    Thanks, still very odd that it lost that data after a flash. That area of the ECM is never modified during a reflash.
