What will this device do?Joey D.Apr 27, 2020
Best Answer:Hello – This is a calibration device that allows you to “re-program” certain parameters, such as the tire size and gear ratio, on select vehicles. The benefit is that, if you have a modified vehicle, adjusting these parameters can restore normal speedometer operation.
