Adjusting the idle stepper screw

This is the screw on the throttle that can be adjusted using the "adjust idle stepper" feature. Rover recommended setting the stepper value to 26 however if you have a non standard throttle body then a different value may well give a better result.

Note that this ECU will normally report error codes for sensors that are not fitted to the vehicle. For example, fuel temperature and 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.
