SL 750 SHIVER
Electrical system
The value in the example refers to engine conditions with key set to ON.
Rear throttle Potentiometer 1 (voltage)
Example value: 780 mV
The value in the example refers to engine conditions with key set to ON.
Rear throttle Potentiometer 2 (voltage)
Example value: 3756 mV
The value in the example refers to engine conditions with key set to ON.
Front throttle Potentiometer 1 - 2 (degrees) / Rear throttle Potentiometer 1 - 2 (degrees)
Example value: 6.5°
With key set to ON, the throttle is kept in position by the springs (approximately 5 - 7°). After the engine
starts up at idle, the throttle is kept close to the mechanical minimum (above or equal to 0.5°). When
the gear is not engaged, at approx. 6000 rpm, throttles open very little because the requested torque
is too low (approximately 5 - 7°).
Front / rear cylinder throttle correction
Example value: 0.0°
For example, if there is a hole in the intake manifold, the pressure read is different from the pressure
estimated by the control unit and the system tries to reach an "estimated" situation by opening the
throttle a little bit more; therefore, this parameter takes a value different from zero: an acceptable value
should be between -0.7º and +0.7º.
Front cylinder Limp home position / Rear cylinder Limp home position
Example value: 800 mV / 780 mV
Voltage stored in the control unit corresponding to the throttle Limp home position.
Front throttle lower position / Rear throttle lower position
Example value: 502 mV / 492 mV
Voltage stored in the control unit corresponding to the throttle mechanical minimum position.
