Some controlled devices by the ECU (ECM) would be, fuel injectors, idle air control (IAC) valve, fuel pump relay, linear EGR solenoid valve, electronic ignition control module, fuel tank vapor pressure sensor, a/c compressor relay, evaporative emissions (EVAP) canister purge solenoid, to name a few.

What does ECU stand for?
Electronic Control Unit (ECU) controls the fuel injection system, ignition timing, and the idle speed control system. The ECU also interrupts the operation of the air conditioning and EGR systems, and controls power to the fuel pump (through the control relay). 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.).
Is a ecu same as a ecm?
yes the ecm and the ecu is the same thing. ecu stands for electronic control module and ecu stands for electronic control unit. they are both the same thing just ecm in canada and ecu in america.
