Description
This speedometer calibration kit is a programmable CAN node. It can be used to correct the speedometer and odometer for vehicle conversions with tire rolling circumferences that significantly deviate from the standard tire size. This makes it possible, for example, to make larger tire rolling circumferences or differential modifications acceptable.
How it works
The ABS/ESP control unit sends a speed signal to the instrument cluster via CAN bus. The speedometer calibration kit is installed in front of the instrument cluster and corrects both the speed signal and the odometer in real time. The correction factor can be programmed via a USB interface.
The original wheel speed signals are retained. Therefore, the function of the ABS/ESP control unit cannot be impaired.
Correction factor: 7% (other values on request)
The control unit has an E-mark and is therefore exempt from registration.
