Tire Size Variable ECM Specific Location
I have the Chrysler Diagnostic Application on my PC connected to my Jeep and am monitoring all CAN activity, and it appears I can change things using this application. My question is does anyone know what the programmers out there change when re-calibrating the speedometer? There are a lot of variables that can be changed, but I cannot find one specific to tire size. It also appears I can change tuning specs also, this could be a way to go instead of buying the programmer for me or having the dealership re-calibrate for $75.
I am going to ask superchips and a contact at Chrysler, but these can take a few days. Will post back if I find anything out.
