    Smile Gm Seed key algorithms

    Great find. It does save me a lot of work, reinventing the wheel.

    Too bad Gm changed the algorithm recently.

    Now it is time to make a chart with the PCM hardware id and OS/engine RPO vs algorithm number.

    Thank you for sharing. However, I saw nothing in the document to indicate it's source.

    What a neat idea.
    I am interested in seed / key algo for a BCM. Does it follow the same format as the PCM routine posted earlier?
