Description
Advanced Recalibration Tool. Installing larger aftermarket tires causes inaccuracies in your truck’s speedometer readout. That’s what this Rough Country Speedometer Recalibration Tool has been designed to correct. It reprograms your vehicle’s onboard ECM to match the output of your newly installed larger tires so you can accurately determine your vehicle’s performance.
Accurate Reading. The program installed on this Speedometer Recalibration Tool effectively corrects the discrepancy between your actual speed and the readout on your speedometer based on the size of the aftermarket tire installed on your vehicle. This device has also been engineered to update your truck’s onboard computer to ensure correct shift points and accurate electronic control.
PC-Compatible. The installation of this Speedometer Recalibration Tool requires an updated version of the Inline Speedometer Corrector Programmer. As such, this tool is compatible with most PCs and may be upgraded by connecting to a Windows-enabled computer.
