Hypertech In-Line Speedometer Calibrator (14-21 Tundra)

Corrects Speedometer / Odometer. If you have installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, Hypertech’s In-line Speedometer Calibrator Module allows you to correct your speedometer and odometer readings. The vehicle’s computer calculates your speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is actually going. As a result, the speedometer/odometer readings will not be accurate.

Straight Forward Installation. Simply connect the Hypertech In-line Speedometer Calibrator Module to your Windows computer via USB and enter the new tire height and/or rear gear ratio. There are no limitations for increasing tire height or rear gear ratios. Then, 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 speedometer and odometer readings.

Application. This Hypertech In-Line Speedometer Calibrator is designed to fit 2014-2021 Toyota Tundra models.
