Changing the revs/mile in the PCM programming will only mess with shift points and speed limiter functions.

DJ, your "problem" lies in the ABS module, not the PCM at all. If the speedometer is changed, the odometer will change too as there is only one input to the instrument cluster.

I wasn't aware that AE would change the ABS data output to the PCM....
Hmmmmm.
