Get accurate speedometer readouts and proper shifts with the Hypertech Speedometer Calibrator for your L5P Duramax.
Hypertech's In-Line Speedometer Calibrator Module is a plug-and-play module that corrects the speedometer and odometer for non-stock and/or gear ratios. With the included USB cable, connect the Hypertech In-Line Speedometer Calibrator to your PC and enter the new tire size and/or rear gear ratio. There are no limitations to tire height or rear gear ratios. Next, simply disconnect the factory connector to the instrument cluster, snap in the Speedometer Calibrator Module, reconnect the cluster, and you¹re done! In a matter of minutes, you can accurately correct your speedometer and odometer readings. This module is perfect for vehicles with computers that don't allow for tire and gear ratio correction, or to re-calibrate for tire and gear sizes outside the range of programmers.
