In-Line Speedometer Calibrator Module
Hypertech’s In-line Speedometer Calibrator Module is an in-line module to correct the speedometer and odometer for unlimited tire sizes and/or rear gear ratios. This module is perfect for vehicles with computers that don’t allow for tire size and/or rear gear ratio correction or want to re-calibrate for tire sizes and/or rear gear ratios 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. There are no limitations for
increasing tire height or rear gear ratios. Next, simply disconnect the factory
connector to the instrument cluster (behind the dash), snap in the Speedometer
Calibrator Module, reconnect the cluster, and you’re done! In a matter of minutes,
you can accurately correct your speedometer and odometer readings (as required
by law).
