Flashcal for Bronco check engine light

[bandityo]

Just got a new flashcal. My 2024 black diamond just got 35s and wanted to fix my speedo. Updated the flashcal and followed instructions exactly. Changed to 34.5” and saved. Immediately threw service 4x4 and service engine soon light. I test drove and it indeed fixed the speedo but cel still on. Had to tell it to reset all settings on the flashcal and it finally cleared my cel. Funny thing also was when the cel light was on was flashcal detected no dtc codes. I tried to clear it that way and it said I had none yet it was there on the car lol.

So after resetting it back to stock on the flashcal I no longer have the cel but my tires are back to before and nothings fixed.

Any ideas forum ?

There is a PCM and AWD reset you have to do afterwards - in Forscan they are separate procedures you run to clear the P0160 code. If you do this via ProCal they run that procedure for you as part of the speedometer update. Not sure how Flashcal handles it
