One Day Deal Hypertech Spectrum Speedometer Calibrator 3400 | RealTruck

The Hypertech Spectrum Speedometer Calibrator is the latest version from Hypertech. This new device allows you to re-program for correct speedometer readings, as well as correct part-throttle shifting, if you’ve installed tires that are larger or smaller than your factory tires, or if you have installed a ring and pinion gear set with a different rear gear ratio.

In addition, Hypertech’s Spectrum Speedometer Calibrator has the ability to correct, read, and clear Diagnostic Trouble Codes (DTC’s) or “Check Engine” lights, as well as the ability to adjust the TPMS warning threshold when larger than stock tires are installed. This allows owners to view detailed information about the vehicle’s operation without having to purchase expensive diagnostic computers or scanners used by dealership technicians.

The Hypertech Spectrum Speedometer Calibrator installs in less than 15 minutes without using tools or getting your hands dirty. The device plugs into your vehicle’s under dash OBD-II port and you simply select the tire height and new gear ratio. Within a matter of minutes the vehicle’s computer calculates your speed based on the diameter of the new tires. Additionally, the Hypertech Spectrum Speedometer Calibrator is covered by the manufacturer against defects in materials or workmanship for a period of one year.
