As a result, the automatic transmission may not shift correctly and the speedometer readings will not be accurate (as required by law). 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. The vehicle's computer calculates your vehicle's speed based on the diameter of the stock tires. If you've 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, the Speedometer Calibrator allows you to re-program for correct speedometer and odometer readings, as well as correct part-throttle shifting. Speedometer Calibrator Programmer Features Simply plug Hypertech's Speedometer Calibrator into the vehicle's under-dash connector, select the new tire height and/or new rear gear ratio, and in a matter of minutes, the vehicle's computer is reprogrammed for accurate readings (as required by law). For an additional charge, the Speedometer Calibrator can be upgraded to a Max Energy Power Programmer via the internet to include all the Max Energy features available for that vehicle.
