Tuning with OmiCheck
Ensure all electrical loads are off, select 'Tune' and follow the instructions on the
OmiCheck. The OmiCheck will now take you through the tune.
Stepper Motor Setting
The stepper motor is set in the following manner. The engine is kept constant,
controlled by the ECU and will not change. Any adjustment of the air by-pass screw
will change the position of the stepper motor. The OmiCheck uses graphics to instruct
the operator to 'raise' or 'lower' the stepper motor position. The stepper motor position
is displayed on the screen and is only used to guide the operator to ensure the screw
is turned in the correct direction.
