Engine Governor
The ECM governs the engine. The ECM determines the timing and the amount of fuel that is delivered to each cylinder. These factors are based on the actual conditions and on the desired conditions at any given time during starting and operation.The governor uses the throttle position sensor to determine the desired engine speed. The governor compares the desired engine speed to the actual engine speed. The actual engine speed is determined through interpretation of the signals that are received by the ECM from the engine speed/timing sensors. If the desired engine speed is greater than the actual engine speed, the governor injects more fuel in order to increase engine speed.

Typical example
Customer Parameters and Engine Speed Governing
A unique feature with electronic engines is customer specified parameters. These parameters allow the owner of the machine to fine-tune the ECM for engine operation. Fine-tuning the ECM allows the machine owner to accommodate the typical usage of the machine and the power train of the machine.Many of the customer parameters provide additional restrictions on the actions that will be performed by the ECM in response to input from the operator.Some parameters are intended to notify the operator of potential engine damage (engine monitoring parameters). Some parameters enhance fuel economy (machine speed, engine speed limit, and idle shutdown). Other parameters are used to enhance the engine installation
