    Question How To Change Shift RPM? 6r80 2014

    I?ve been trying to tune a 2014 f150 to shift at 6500rpm and can?t seem to make it happen at the desired rpm. It seems to shift somewhat whenever it feels like. Why?

    Changing 1-2 shift (speed vs TPS) higher does not help and neither does Shift rpm WOT. I?ve tried with and without shift rpm anticipation with no change.
    Do I need to move the rpm limiter up? Is the truck thinking it cannot fulfill the shift when commanded so it just shifts when it wants?

    lowered the max acceleration:

    raised max accel plus raised shift rpm wot and raised clutch fill time 1-2
    Greedy Tune 21 high timing File Duane F150.hpttune 21 pull.hpl

    Id love to hear murfie or erics input on this!

    You will need to increase the max shift speed max shift RPM to start. There are a few other things as well Ill take a look and send you a revision. Also what size wheel tire combo are you running on the truck? Is the rear differential 3:31 or has it been modified?
