swapped gearing to 3.45, updated ratio and tire size now got abs light. I had no lights before update. Is there something i'm missing here? Figured it would be best to update for the speedo. original was 3.09 with 29.7 tire size. I didn't change tire sizes but manufacture said my diameter is 30.4 so that's what i put.

Hey,

you must set the right gears into the tune. The pcm interpreted the wrong wheel spin.
Tire size is ok, there is space to use different tires.

scratch that ^^^

you must enter whatever numbers allow:

1) proper transmission shifting

2) no cel

3) accurate display of speed

for my zf8 auto trans, 3.70 manual trans rear diff and 3500 stall 2016 challenger on drag radial it ended up wanting 3.42 in special features

do you see the 3 pid i use for this:

***after a calibration do a 20 mile drive because the system is semi self adjusting!!!
