Injector Control

INJECTOR CONTROL

The MS S52 control module calculates the correct injection time based on the control parameters of:
- Engine speed.
- Air mass.
- Throttle position.
- Oxygen Sensor feedback signal.
- Engine coolant.
- MS S52 Barometric pressure.
- Battery voltage.

The injectors receive operating power from the main relay and the control module provides the ground for the duration of the injection time (MS value).
