Q: Speedometer and odometer off

asked by on

My speedometer is off anywhere from 5 to 15 MPH, depending on the speed I am driving. In addition, the odometer is only registering 0.8 of a mile, for every actual mile being driven.

There are speedometer calibration tuners available for the Ranger. Hypertech makes one; it is typically used for calibrating for different-sized tires. According to Hypertech, this will correct the odometer reading as well.
