Description
Corrects Speedometer / Odometer. If you have installed a set of 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, Rough Country’s Speedometer Calibrator 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.
Diagnostics Tool. The Rough Country Speedometer Calibrator can also be used as a diagnostic code reader. Save yourself time and money by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.
Easy to Load; Easy to Restore. When you make changes to your vehicle, the Speedometer Calibrator automatically stores your vehicle's factory settings. To return to the original factory settings, just plug the Calibrator back in, select the option to restore the factory settings, and you're done. This is ideal for visiting dealerships for warranty work. Once you have the vehicle back from the dealership, reinstall the Speedometer calibration as before. Please note that the Speedometer Calibrator can only be used on one (1) vehicle at a time.
Internet Updateable. The Rough Country Speedometer Calibrator comes with a USB cable to enable quick updates over the internet. If your vehicle has a new calibration not available when your Rough Country Speedometer Calibrator was manufactured, it is possible that you will see a “Cal not found” message on the 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 here. Then click on the download updater button to get the latest releases.
Application. This Rough Country Speedometer Calibrator is designed to fit 2007-2016 GMC Sierra 2500 HD models.
