ECU (also known as ECM – Engine Control module, PCM – Power-train Control Module) of ‘300zx Ecu' means Electronic Control Unit. In internal combustion engine metered engine fuel (car gas) through carburetor or fuel injection unit is mixed with air and compressed in the metered inside space (like 300 cu in) of the engine block. At the optimal pressure and temperature combination the spark plug initiates a spark to complete the combustion and get maximum torque power to drive the car forward through transmission line and gears. Previous to the microprocessor age mechanical timing used to control the spark ignition of different engines. In this high tech world digital control is the name of the game. Microprocessor monitors many input variables (like pressure, temperature, oxygen content, unburned gas etc) sensed by the reliable sophisticated sensors

            ECM is one many electronic control units (ECU) used in the present cars. Sometime the electronic control unit is called embedded system or car's computer (some cars have more than 80 computers). Here are few examples of electronic control Units:

                        . Air bag control unit (ACU)

                        . Convenience control unit (CCU)

                        . Door Control Unit

                        . Engine Control Mule (ECM)

                        . Man machine Interface (MMI) – Like interface to GPS

                        . Onboard Diagnostics (OBD)

                        . Power-train Control Module (PCM)

                        . Seat Control unit, Speed control unit

                        . Telephone Control unit, Transmission Control Unit
