The issue we have is that the speed & odo are not accurate and that they can not be calibrated.
We do TSD rally and find both the speedometer and odometer off. This could be compensated somewhat IF the delta was consistent, it varies with speed.
This was validated with both GPS and a Nu-Metrics NiteStar Distance Measuring Instrument running off the OBDII. With the Nu-Metrics a factor can compensate only if the delta is linear, it is not.
