Hypertech 2012-2015 Toyota Tacoma Speedometer Calibrator 730117

Features:
If you've installed tires that are larger or smaller (up to 50% smaller) than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Speedometer Calibrator allows you to re-program for correct speedometer and odometer readings, as well as correct part-throttle shifting. The vehicle's computer calculates your vehicle's 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 going. As a result, the automatic transmission may not shift correctly and the speedometer readings will not be accurate (as required by law). 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. In a matter of minutes, you can accurately correct your speedometer and odometer readings.

Internet Updateable
The Speedometer Calibrator comes with a USB cable and a CD containing software to enable quick updates or upgrades over the internet. If your vehicle has a new calibration not available when your Speedometer Calibrator was manufactured, it is possible that you will see a "Cal not found" message on the Speedometer Calibrator screen. If this occurs, you can simply update your Speedometer Calibrator with the correct new calibration via the internet. Simply connect the Speedometer Calibrator (using the provided USB cord) to your computer and go to www.hypertech.com. Then click on the Support button to get update downloads. You can also get the update downloads using the supplied CD which in addition contains an installation video and a printable version of the instruction manual.
