CAN-Bus technology

The Speedometer-Calibrator is a programmable CAN-node. This can be used on vehicle conversions using different rolling circumferences to correct the speedometer and odometer. This can make tire conversions or changes to the differential road legal.


The ABS/ESP-ECU is sending a speed signal via the CAN-Bus to the instrument cluster. The speedometer-calibrator is installed in the CAN-bus next to the instrument cluster and corrects both speed signal and odometer signal in real time. The correction factor can be programmed via our USB-interface.

The original wheel speed signals are maintained. Therefore it cannot influence the function of the ABS/ESP-ECU.
