    Default PCM Flash History

    On the flash history: Is Calibration History 1 the newest or is Calibration History 10?? In a new stock pcm I have history 2-10 listed as 4294967295 and History 1 as 92509176. I am assuming it has been flashed once with a flash with a different CVN, but don't know what the most recent flash was. The 4****5 or the 9****6. This is on a 18 Cadillac ATS-V that came to me as the original purchaser but it was a GM car for 1400 miles. I was just checking it to make sure somebody hadn't tuned it already which might raise warranty questions months or years down the road.

    And why would History 2 through 10 be the same part number? I though only flashes with a different CVN were recorded in the history. All this info is from Global Diagnostic System 2 rather than my V2 as it is off with my track car in Az.

    4294967295 = $FFFFFFFF in hex, in other words it is blank and never been used therefore what is in there is correct.
    I no longer monitor the forum, please either post your question or create a support ticket.

    That explains it! So it has been flashed once and not yet reflashed.

    Thanks as always!
