An electronic engine control system (EEC) is a small computer that controls a car's engine. It's mounted on the engine or engine fan case and draws power from an engine alternator. The EEC monitors flight and engine conditions, such as: Fuel flow, Temperature, Vibration, Pressure, Throttle position. The EEC's purpose is to optimize flight performance while protecting the engine and aircraft from safety risks.
An electronically controlled engine also has an electronic control unit (ECU). The ECU is the central controller of the engine management system. It controls: Fuel supply, Air management, Fuel injection, Ignition, Wheel speed, Braking power, Idle speed, Air/fuel mixture. The ECU monitors multiple factors such as engine speed, load, and temperature to enhance power output and fuel economy. It also adjusts the fuel injection rate to give the right power as needed.
