    Operating System Question

    Does the OS information get saved in the hpt file?
    I've looked at a couple hpt files I downloaded to learn but it doesn't seem to be there.

    The reason I ask is that I have built a bench unit to play with and am waiting for some used PCM's to arrive to learn on.

    Regards,
    Jeff

    Yes. OS numbers are found in Edit > Calibration Details > Controllers

    I'm sure someone else will add but I don't think you can from HP Tuners. I use SPS in GM to do all of my updates. TAC and pedal issue. Must be talking about throttle progression issue on trucks. Feels like you are pulling a trailer. The factory GM software fixes that problem very well.

    HP Tuners tune file only contains and can only read/write 6 of the 8 segments in a Gen4 ECM. The two it can't touch control the throttle.
