TruSpeed™ Speed Sensor Recalibrator
 |
Virtually every vehicle manufactured since 1992 is equipped with an electronic speedometer that uses a sensor to read vehicle speed rather than a mechanical cable. The speed signal is also a big factor in the overall performance equation. When tire height and / or axle gearing is altered, the vehicle's Engine and Powertrain Control Modules receive an erroneous speed signal. This translates into subtle, yet real reductions in performance and fuel economy.
Our TruSpeed calibrator addresses all speed signal-related problems; it doesn't just correct the speedometer. How? The TruSpeed module installs in-line with the factory electronic speed sensor and converts the wrong speed signal into the correct one for your vehicle's new tire and / or axle gear ratio combination. Because the signal is altered at its source, all speed-sensitive vehicle systems will receive the correct speed data, which restores all proper functions. The TruSpeed is available for most domestic and import vehicles equipped with an electronic speedometer.

Corrects speedometer / odometer readings, and the speed signal sent to the Engine, Powertrain, and Anti-lock Brake Control Modules. Besides the obvious, these modules affect fuel delivery, engine timing, and automatic transmission shift points
Eliminates speed signal related reductions in engine performance and fuel economy, as well as related changes in exhaust emissions
Infinite adjustability provides precise speed signal calibration to within 1%
Two settings allow off-roaders that seasonally run different height tires to correct their speed signal by flipping a switch
Simple four-wire hookup
Includes complete instructions and adjustment charts
Can be recalibrated infinitely for future tire size or gear ratio changes
Works on most vehicles equipped with an electronic speedometer
Applications for most 2WD and 4WD GM, Ford, Dodge, Jeep and Toyota vehicles. For more information refer to the Application Guide
