Larger Tires, Can't Fix Speed-O

[nipeej]

I have a 2023 Badlands.
Situation: Went from 33's to 35'S - Speed-O is about 3MPH off.
Used FlashCal to correct problem. Speed-O was corrected but, "one pedal" does not work anymore. Bronco through code P160A. Used FlashCal to reversed the tire settings and "one pedal" works (no code). Decided to go with ForScan and the same thing happened. When using Forscan, is there more than one place were changes need to be made? Has anyone had this problem and corrected it? Help appreciated.

All I know is one of the features of the Ford ProCal is ability to punch in number of revs and you're done. You probably know this, but thought I'd mention it.

You need to do the PCM Initialization in Forscan after you adjust the tire sizing.
