'14-21 Toyota Tundra Hypertech Speedometer Calibrator - 730119

Hypertech's In-Line Speedometer Calibrator Module for the 2014-2021 Toyota Tundra is a plug-and-play module that corrects the speedometer and odometer for non-stock and/or gear ratios. This module is perfect for Toyota Tundra 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. VEHICLE FITMENT: 2014-2021 Toyota Tundra Speedometer\Odometer Correction Speedometer\Odometer Correction For Gears All valid gear ratios supported Speedometer\Odometer Correction For Tire Sizes Lower limit 50% of stock tire size, no upper limit About Hypertech Speedometer Calibrators: Changing tire and gear sizes can have an adverse effect on your speedometer and odometer readings. To correct this, Hypertech has assembled some of the best features from their series of programmers and tuners into one stand-alone unit. Hypertech speedometer calibrators will adjust for a wide range of tire sizes and gear changes (not all applications can adjust for gear changes) to keep your speedometer reading properly without the additional cost of buying a complete tuner. Installation is as easy as plugging one of the calibrators into your vehicle's OBDII diagnostic port, and while you're there, they can even read and clear diagnostic trouble codes.
