6 Overview
ECU Inputs & Outputs
The ECU analyses signals from the sensors, then controls the Fuel Injectors,
Ignition System and other auxiliary devices according to the Calibration and
Setup Data which is stored in the ECUs programmable memory.
The Inputs and Outputs are shown below.

Main Engine Sensors
The Main Engine Sensors are required for correct operation of the ECU.
The engine RPM is derived from the REF trigger sensor.
The SYNC trigger sensor is required to synchronise the Fuel and Ignition to
the correct engine cycle for sequential injection and correct firing of multicoil
ignition systems.
