so can you check how that car checks for catalist eficiency while your at it in the documents one needs to know this stuff . for the future .

Sorry Intrade I was looking at parts info not service. Doesn't look like they check cat efficiency at all, I'm guessing it's a dumbed down system that only has basic exhaust measurements to adjust the mixture

On a further note, some of that model DID have the option of a second o2 sensor (not this one though) as it was shown in the parts book but listed as not applicable (hence the other incorrect ECU, clearly from a 2 sensor system).
Also, oddly, the ECU p/n wasn't recognised or priced, which is probably why your first dealer couldn't help. I could see the ECU p/n in ASA was similar to the number you had given me. Most likely not loaded into MMNZ's system as they've probably never sold one before

The correct ECU part number for that chassis is 8631A606. It is possible to turn off periphery bits within the ECU to disable functions or force lookup responses but its time comsuming and requires dissasembly with software like hex rays IDA pro https://www.hex-rays.com/products/ida/. I woundnt waste time with the JOBD protocol, MUT is quicker thanks to faster baud and much more comprehensive

Glad ya found the problem. Now you just gotta find the right ecu. That's half the battle sometimes.
Have you opened the old one up? Is it repairable?

The old ecu is the wrong one thats the ecu number above. Yes it was repairable just a blowen transistor on board from someone connecting the speedo wire to earth when installing radio. Car came into country with speedo not working check light on. Two codes current sensor fault (not fitted ) and rear 02 sensor (not fitted) Also the ecm mounting bracket missing. I came to conclusion incorrect ecm incorrect I phoned mitsi no help. So left it in the hands of the parts guy whom got another ecm off a 4a90. This ecu is also incorrect Just one code rear o2 sensor Now I have the right number I can try and track another ecm.

a.woodrow can you check the emission compliance of that is that euro 4 only and the other euro 5 ? or are they the same .
