Calibrate speedometer on 2006 Jeep

[akdsmer]

I imagine most tire shops can recalibrate and electronic speedometer. May even convince them to throw it in with the tire purchase.
.

I doubt that most shops can. Most scan tools cannot do this bi-directional function, as it is DRBIII (or 4) specific. Genysis, Snap-on and AutoEnginuity don't support this function for sure, and the first two are the most widely used scan tools out there.

Let me know if there is someone out there doing it, that would be good information to know.
