    Is that your stock tune? Or have you made some changes already?

    Never mind. Looks like you (or someone else) made a lot of changes.

    If in doubt, multiply everything by 1.1.

    Drive your truck around and log shift ID and clutch shift type and post the log.

    While you're driving about half way through, switch to tow mode if you have it.

    Need these channels:

    shiftid.jpg


    shifttype.jpg


    If you don't have them, request for them to be added for your application.

    Without those you cannot properly tune an zf8hp trans.

    Well, you can start by adjusting shift schedules (shift points) in the tables indicated in your log. It looks like maybe someone turned your upshifts WAY up already? Hope you have some engine mods for that.
    You can also work the down shifts so that it is more eager to downshift for better response. The numbers are output shaft speed - which you can log to figure out where you are. Lower gears (1-2nd mostly) are going to have a bit of lag time for the shift so you will need to command an upshift before you get to the OSS where you really want it to shift.

    You can also try bumping up desired line pressures in general. Stay under 22 bar.

    Then after flashing in the new pressures, reset trans adaptives and do a quick learn with the scanner.
    If in doubt, multiply everything by 1.1.
