4. Calculations
You need a good speed reference, such as a GPS, radar speed sign or another vehicle
with accurate speedo.

Repeat the measurement to make sure you get consistent results. Then use the following
formula to get the calibration value you need:

Example:
If your indicated speed was 66 mph at 60.0 mph actual (reference), the
calibration value would be: -9.09%
