The electronic control unit (ECU ) receives information regarding engine speed, crankshaft angle. coolant temperature and throttle position. An air flow meter also measures the volume of air entering the induction system.

Fuel delivery, Ignition timing, and dwell angle are incorporated into the same ECU to create a 3-dimensional map of the engine parameters relating to engine speed and load, stored on a chip.

Crank position and engine speed is determined by a pair of sensors reading from the flywheel (or toothed pulley at the front of the engine on later models). A separate constant idle speed system monitors and regulates base idle speed settings.

On early systems, a 5th injector is used to provide extra fuel enrichment during different cold-start conditions.

Depending on application and version, an oxygen sensor may be fitted (the system was originally designed for leaded fuel).

Once the ECU has received all the correct signals from its sensors, it will fire the injectors. The ECUs have 2 injection outputs, and the injectors are arranged in 2 "banks" which fire once every two engine revolutions. In an example 4-cylinder engine, one output controls the injectors for cylinders 1 and 3, and the other controls 2 and 4. The system uses a "cylinder ID" sensor mounted to the cam-shaft to detect which cylinders are approaching the top of their stroke, therefore which injector bank should be fired. During start-up (below 600 RPM), or if there is no signal from the cylinder ID sensor, all injectors are fired simultaneously once per engine revolution.
