    Speedometer Calibration.

    Have a 2002 GT Mustang that belongs to my father. Wanted to calibrate the speedometer for the gear change that was done to the car and I set the proper values for axle ratio but observed no change to the speedometer cal. Adjusted the VSS tire revs per mile, again, no change. Is there another table that I am missing?

    Just in case anyone else is wondering or looking. Flip the Use VID bit in the speedo section under hardware. Got the speedometer dialed in this morning.
