Injection pulses usually occur one or more times per engine cycle. The ECU uses a trigger
signal locked to engine speed in order to determine when to inject. When it receives an
appropriate trigger, the ECU applies a magnetising current to the injector coils for precisely as
long as the final computed injection time, providing an extremely accurate delivery of fuel
that will exactly suit the engine's needs.
The ignition timing is determined in a similar way to the fuel needs. The ECU has a table
configured for ignition instead of fuel and applies corrections in a similar way.
