i have a new mazda 3. the ecu has blown due to a service station idiot pressure washing my engine. the ECU is located near the intake over the engine. anyway, car was evaluated by Steve in Ben lomond. i was told the ECU is irrepairable. i would need to buy a complete ECU, but would also need an ignition system with key and keyless entry button in order to get the car going again.

so what are my options? i got an ECU locally from a crash sigapore car. but no ignition. however, we plugged it in, and the car managed to tumble but it would not start. can the ECU be re-programmed to recognise the ignition?

how can i source an ECU? the car is out of singapore. i cant seem to find a part number on the old ECU since its toally toast.

anyone with knowledge in this area?

padna most of the newer cars the key has a built in immobilize that operates the ECU. So plugging in another ECU won't help at all. What you can do is get the ECU and Keys from the crashed one and that should work

laser cut key?
factory immobilizer?

Give High Tech locksmiths a call (St Augustine)
They MIGHT be able to help, if you got a replacement ECU.

if it is dat the ecu has the immobilsier built into it then you could use your key an reprogramme it to work, if the immobilser was external to the ecu then i wont see how it was affected wen the brain got wet? but i never really dealt with those mazda 3 in depth.

carry the blown ecu buy this man victor 680 8087 he from south he fixes these things

Yeah, victor whiby. Spoke to him. He said he can't resurrect the dead. You see, my ecu has a big hole in it. Contacted a guy named vishnu from central. Anyone know him? He said he can reprogramme the ecu. Got one today from a singapore crash

i could reprogram the ecu 734 2863

yeah,its programmable, if you dont get through with any of those guys, let me know, I can give it a try...

this is my old post. when a car is a lemon, its a lemon. i got the car going with a replacment ECU. it was sold to a tuner and after 1 week the new ECU blew again. i understand it was sold again and again the new owner had the same issue. funny this post should resurface again because just last week i saw the said car parked up by an electrician.it was covered in dust.

who in their right mind buys new mazda? besides TL
