    10r80 on f150 help upshifting at wheel spin and short shifting from raised points

    Need a bit of help on tuning my 10r80
    so I believe a raise all the limits and was able to get it to shift at 7200 rpms at wot
    i raised my oss to shift at 7750 and for some reason im being shorted about 500 rpms
    also shifting into 2nd its commanding 3rd before even being on 2nd I understand it might be able due to wheel spin but its not reaching anywhere close to the shift point

    thanks in advance here is the log,tuned and stock file thanks

    Can you add ALL of the "source" pids to your channel list?

    On your shift from 1st to 3rd issue, sounds like your traction control is doing exactly what its designed to do.

    Try turning advance trac off or unplugging the "dyno" plug

    What does force the shift schedule mean?

    Had to disable anticpated shifts and also disabled torque based shifting, might not be the correct way but it sure fixed the issure and gave me the shift points i was looking for.
