Setting the correct ignition timing is crucial in the performance of an engine.

There are many factors that influence proper ignition timing for a given engine.

The same procedure is used for controlling the ignition timing of the rest of the cylinders.

Smaller propellers reduce the load, and therefore the compression pressure build up, which changes the ignition timing to earlier.

Engine knock control is used to allow the ignition timing to continually approach the point of detonation.

Fuel delivery, ignition timing, and dwell angle incorporated into the same control unit.

The loose chain causes inaccurate ignition timing which usually results in noticeable rough running.

Should the ignition timing be changed for use of the vehicle at higher altitudes?

This data from the sensor is then used to adjust the fuel injection and ignition timing.
