Speed meter indication error Speed Meter indicates speed and actual speed according to formula :
O ≤ Vn-VZ ≤ (V: + 10) + 4
V1- speed meter indicates speed in km/h;
V2- an actual speed in kilometers per hour (km/h).


The vehicle speed correction is based on 100km/h.

The error of the vehicle in the low speed state is the reason why the original vehicle meter is not linearly displayed.

Specifically, you can connect to the OBD socket test with a dedicated instrument in the 4s shop.
