That's cuz we are talking about real tuning software
 not Gryphon for Gassers. AE has a tire size adjustment under the ABS PCM diagnostics.... Minotaur has settings for Revolutions per mile... that value is available in the specs from the tire manufacturer for my new tires is 634... also a pulse per revolution of the speed sensor. its snowing and dark now so may wait on playing with it till later

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.

yep it will and the last time I messed with it I was able to bump everything up so setting the tire size at 35" I was able to ge it like 10-20 mph over what it was supposed to be but for some reason I cannot get it to drop the last few MPH.... maybe I will contact AE and see what they have to say about it.... need to mess with it some more first... I tried setting it to stock tires size a few times which is 1 1/2 inches less diameter... but it doesn't change

I know that the older trucks only allow for a change so many times before they just quit allowing it anymore. Not sure about the Super Duty-based trucks (or Excursions
 )

Sorry I couldn't resist that one
 ya made it too easy I did talk to Bill a long time ago and remember telling me it usually did not change the speedometer... but it did correct the speed for the shifting strategies. Ill check with the dealer on if there is a limit on the abs module for changing the tire size... if so, maybe the ABS module can be reflashed to reset that
