Be especially careful when doing this calibration – since it requires
you to read the prompts and press the Select button at the
appropriate time, while you are operating the vehicle, you need to
be extremely careful during this procedure and pay close
attention to the track and other traffic that you might encounter.
There are several limitations to note with this method:
1) if you have tire slippage, an incorrect gear might be computed (due to the engine running at a
higher rpm than normal in that gear for the speed you are travelling)
2) there is no recording of a neutral (neutral cannot be determined with this method)
3) a change in tire pressure or diameter, or a change in the gear ratio (e.g., motorcycle front/rear
sprockets), will generally require that this method be recalibrated
You have the option, via the calibration menu, of calibrating one gear at a time, or all gears at
once in succession.
To calibrate, highlight the
