    Doesn't matter what I try, random knock counts upon communication connection.

    I've tried everything. It's gotten to a point where I'm going to ignore the knock counts.

    Only problem is that I am not sure that the knock counts that show up are random or stored in the ecm.

    In any case, the counts don't increase as I am driving.

    It occurs before start up, after start up, before warm up, after warm up, it really doesn't seem to matter when I connect and start tuner, it occurs.

    It's an accumulator, there will always be knock counts. The only way to find knock in this ECM is to watch data and see knock counts increase.

    Your still running the bin I gave you? It has the forced knock ESC test done, so it will not force knock at WOT PE as a test either.

    In all your logs I've seen I've never seen knock occur. As I said it will always have a number, don't worry about it unless the number is moving/increasing!

    Thanks Mark!

    Just did not want to worry about adjusting something that was not an issue.
