Hypertech's In-Line Speedometer Calibrator Module is a plug-and-play module that corrects the speedometer for non-stock and/or gear ratios. This module is perfect for vehicles with computers that don't allow for tire and gear ratio correction, or to re-calibrate for tire and gear sizes outside the range of programmers.
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 correct speedometer and odometer readings. 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 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. Next, disconnect the factory connector to the instrument cluster (behind the dash), snap in the Speedometer Calibrator Module, reconnect the cluster, and you're done! In a matter of minutes, you can accurately correct your speedometer and odometer readings (as required by law).
The key to the quality of Hyerptech's Jeep performance chips is the way Hypertech tunes. Hypertech was key in the development of the power tuning process. Hypertech's power tuning allows its chips to read the maximum amount of Jeep sensor data and, using sophisticated algorithms, finely tune the car's combustion processes to burn the fuel and air mixture in the way that is the most efficient for your Jeep application. Hypertech has been producing quality performance chips since its founding in 1985. The team of engineers at Hypertech spans the disciplines of engineering, computer science, and mechanical engineering. This wealth of knowledge allows Hypertech to develop Power Chips and Power Programmers that will drive the highest level of performance from your Jeep application. Shop Hypertech Now
