Corrects speedometer readings after installing non-stock tire sizes or changing rear gear ratios Correct speedometer for accurate readings (as required by law) for tire sizes up to 54” Large 4.3” full color screen with user-friendly navigation for simple installation/feature changes Easy to view color screen even in direct sunlight Read/display/clear diagnostic trouble codes 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). Show more
