Calibrate Mode
Calibrate mode is used initially to automatically calculate the odometer ratio if it is not known.
It is also used periodically to adjust for slight variations between the odometer and the VM. If
any of the counter fields is used for engine hours, you do not need to perform calibration, as
the VM keeps very accurate time.
