Ecu/ecm/pcm what will have to be done to it?


You'll have to go back and get the body control module/integrated control module. If you have a factory radio, you might want to grab that also, yours won't work with the other computers. Once you have all that, start replacing them in your car. The key/immobilizer sends a signal to the BCM. If it is right the BCM sends a signal to the PCM. IF that is right, the PCM lets you start and drive the car. Many wires to check before spending money. Known people to do this only to find out they had one broken wire that shut down the system.

Working in a mazda mpv 2001, i cant find the ignition control unit, when i look for the part on ebay they sell the part as: ECU-ECM-PCM, question: is the ignition control unit inside the ECU-ECM-PCM?


It appears from a wiring diagram that there is no ignition control module. The ignition coils' primary circuits are grounded through the PCM. And the wires to the sensors are all from the PCM.

Here is a link if you want to see all your wiring diagrams. I found the above information under System: engine; Subsystem: fuel controls.

Where is the ECU located on a 1992 ford explorer and what does it do?


What your Explorer has is actually called the EEC-IV. It is sort of like an ECU. The EEC stands for "Electronic Engine Controls". Your EEC-IV Does this:
  • Powertrain Control Module (PCM)
  • Throttle Position (TP) sensor
  • Mass Air Flow (MAF) sensor
  • Intake Air Temperature (IAT) sensor
  • Idle Air Control (IAC) valve
  • Engine Coolant Temperature (ECT) sensor
  • Heated Oxygen Sensor (HO2S)
  • Camshaft Position (CMP) sensor
  • Knock Sensor (KS)
  • Vehicle Speed Sensor (VSS)
  • Crankshaft Position (CKP) sensor

The EEC microcomputer circuit processes the input signals and produces output control signals to the fuel injectors to regulate fuel discharged to the injectors. It also adjusts ignition spark timing to provide the best balance between driveability and economy, and controls the IAC valve to maintain the proper idle speed.
The EEC is located in the engine compartment. Post your engine size and I can tell you where it's at.
