In-Line Speedometer Calibrator (730127) by Hypertech®. Hypertech’s In-line Speedometer Calibrator Module is an in-line module to correct the speedometer for non-stock tire sizes and/or rear gear ratios. This module is perfect for vehicles with computers that don’t allow for tire size and/or rear gear ratio correction or re-calibrate for tire sizes and/or rear gear ratios 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 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 readings (as required by law).
Since its founding in 1985 in Tennessee, Hypertech® has been an industry leader in engine power enhancement through the use of software enhancements. In 1986, Hypertech created the original "power chip" which physically replaced factory engine control computers and increased horsepower and torque through remapping of computer-controlled fuel injection and ignition timing. As computer controls spread to other vehicle systems such as transmissions, throttle bodies, and variable-valve timing over the years, Hypertech was instrumental in software development that maximized the benefits of each of those systems to push the envelope of performance and fuel economy. In 1994, Hypertech was instrumental in creating the Power Programmer application which made it possible to download software enhancements into an existing ECU, which eliminated the need for replacement chips. Hypertech continues to lead the way today, and our virtual store is proud to sell their range of innovative tuners that offer features competitors haven't even thought of yet.
