Hypertech Speedometer Calibrator Chrysler Speedometer Calibrator Chrysler

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 Max Energy Spectrum allows you to re-program for correct speedometer 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). See more
