    Something is really not right for you. I suspect either:
    - you have a dodgy PCM. There are no response from PCM and retires in the above which are irregular.
    - questionable electrical connection from the ODBII port to the PCM. Are you able to try flashing that PCM on a bench harness?

    If you were doing a calibration only flash the bootloaders would not have been updated so the flash should not have bricked the controller.

    Actually I notice also that your sig has 98Z28, yet the OS reported is 9360361 which is the 99+ LS1 PCM?

    Yeah, same person. That log is the same as posted in the other thread.

    Interested in the result of the 98Z28 and 99+ PCM question. I definitely am not suspecting an EFILive hardware or software here, but of course am also not ruling it out absolutely.

    So this is a converted PCM?
    A '99 .tun in a '98 PCM might cause some problems.
    I noticed a lot of extra wiring in the sig maybe a low battery or
    noise in OBD port causing flash issues.

    Would definately be interesting to see it flashed on a bench harness.

    yes my flashes are taking too long, then failing. My camaro is a 98 and is currently being updated to 2002 harness and pcm, but the firebird is a 99.

    Just to remove any confusion this is the PCM in the 98 (updated) or 99?
