Keep Your Computer Reading In-Line With Larger Tires
Our In-line Speedometer Calibrator Module is an in-line module that corrects the computer reading for vehicles with computers that don’t allow for tire size/rear gear ratio correction or tire sizes/rear gear ratios that are outside the range of programmers.

Installation Is A Snap
Using the USB cable connect the In-line Speedometer Calibrator Module to your PC and enter the new tire height and/or rear gear ratio. Next, simply disconnect the factory connector to the instrument cluster (behind the dash), snap in the In-line Speedometer Calibrator Module, reconnect the cluster, and you’re done! In a matter of minutes, you can accurately correct your computer reading (as required by law).
