Definition of ECU(Electronic Control Unit)
The Electronic Control Unit (ECU) controls the fuel injection system, ignition timing, and the idle speed control system.

The ECU consists of an 8-bit microprocessor, random access memory (RAM), read only memory (ROM), and an input/output interface.

Based on information from the input sensors (engine coolant temperature, barometric pressure, air flow, etc.),
the ECU determines optimum settings for the output actuators (injection, idle speed, ignition timing, etc.)
