An Engine Control Unit (ECU) is an abbreviation for engine control unit. The unit serves as a micro controller (microcomputer) that comprehensively controls the engine operation using electric auxiliary devices. It is widely used in the engine control units of cars and motorcycles aiming to improve the engine performance, fuel efficiency, cleaner emission of exhaust gas, and drivability.

DC power supplies for ECU circuit drive and control are all available in a wide lineup of Matsusada Precision. Furthermore, when evaluating ECUs such as motors, a combination of a power supply and an electronic load can be used to prevent damage to the power supply or ECU from reverse electromotive force from the motor.
