Both ignition and fuel injection timing are controlled by the ECM (Engine Control Module) Basically a computer. It calculates firing and fuel delivery positions by use of a Crankshaft Position Sensor located normally at rear of engine, and a Camshaft Position Sensor. These signals are fed to the ECM along with additional data from other sensors such as Manifold Absolute Pressure, Engine Vacuum, Engine Temperature, Engine RPM, and Exhaust Oxygen level to determine how much fuel to deliver, and how much "advance" for ignition, and which cylinder to Fuel or Fire at a given time.
