Tuning features

Note that this ECU will normally report error codes for sensors that are not fitted to the vehicle. For example, ambient air temperature sensors are typically not fitted and so associated error codes may be ignored.

The ECU will also report strange results or report 'Invalid Value' in live data for sensors that are not fitted.
