hey yall i heard ford will reprogram my speedo for bigger tires im running 32s on a 2007 xl 2.3l ranger anyone know anything about this?

 

2001 and up speedometer calibration is done in the engine computer

Look on the Forscan forum for info on doing that

Forscan is a software that you use on a tablet or laptop
You need a USB to OBD2 cable to connect to a vehicle, some Bluetooth units work as well
Its like an OBD2 reader but WAY MORE FUNCTIONS

I know you can program PATS keys in most years, and I thought I read you could calibrate speed signal as well

Local speed shops can do it and of course a Ford Dealer can do it as well, you need the Ford Software to "talk" to the computer, Forscan is Ford software, but not owned by Ford, lol
