Hi Guys,

I'm new here. I need help on my newly transplanted CK. I replaced my 4g13 Carb engine with a 4g15DOHC. My ECU Part number is MD331036. I hope you could help me out with the pinout diagram for this so I could tap wiring for my Main fan to work when the engine is going beyond normal operating temperature.

Thanks,
Dennis

Sir, I tapped a wire from the ECU (pin#21, blue wire) to a new Bosch Relay. It started working and shut off automatically as well. Do I need to place a diode between the relay and the ECU so that there won't be any charge returning to the ECU? Sometimes the CHECK ENGINE comes out but everything is working fine (idling, temp, fans, aircon, etc) so i'm guessing this has something to do with the wire that I tapped into. Kindly share your inputs.

Thanks!

I am also interested in looking for a pin out diagram of the 4g15 dohc. Anybody has it?
Thanks

Hello out there, I own a Mitsubishi mirage with a fuel injection engine and ecu. I am encountering a hard starting problem. It usually takes about 10 tumbles before the engine starts. My mechanic suggests it may be the ecu. Anyone out there can advise or assist. Thanks in advance

Hello Guys, i have 4g15 dohc engine, i hv done basic modifications like direct airfliter, fuel regulator, Irridium s plugs, thick s plugs wires, big exhaust pipe 2", AND competition muffler, i would like to know where can i re map my ecu box based upon these modifications. thanks

I would need the pinout as well for my 4g15 dohc, ecu part num: MD331036.

I am encountering delay with the idle up/servo when using the a/c. when I turn on the a/c the idle would fluctuate downward first before the idle becomes stable. When the a/c disengages, the idle would spike to 1.2-1.4 rpm before it becomes stable. It is more like a delay between the servo and a/c. I was not able to find the person who wired the engine before and other electricians wanted to redo all wirings wherein it is very costly.

thanks
