Engine Control
Automatic Engine Adjustment
There is a variation in engine RPM depending on each machine. To finely control, in each mode or to eliminate wide variation in
idling RPM, store the setting RPM to the controller at an early stage. This is called automatic adjustment.
When replacing a new controller or a throttle motor or adjusting and replacing control link between the engine and throttle
motor, automatic adjustment must be done.
Note: If a new throttle motor is fitted or the cable/linkage adjusted, the controller must have its memory wiped before
programming can commence.
Automatic adjustment explanation
1. Engine RPM at the time of full throttle: FULL is read.
(H mode MAX )
2. While monitoring engine RPM , RPM is decreased automatically.
RS = FULL-D1
RL = FULL-D2
RI = Idling revolutions = 900 rpm
When each RPM is reached, position of a throttle motor, PS, PL and PI are read.
3. PS , PL and PI are stored by the controller.
Refer to adjustment instructions for automatic adjustment method.
