I'd just get one from a wrecker - shouldn't be too hard to track one down as it's not a part that people would be asking for much. There are places that repair them but I wouldn't expect that to be much/any cheaper - www.ecu.co.nz does it (I'm in NZ - no doubt there's places in Oz that do this). If you want to go aftermarket there's lots of choices, but the price goes up to buy the bits and then tune with rolling road - unless you plan on doing major engine mods it's hard to see how that would be worth it. Are you sure your problem is in the ECU? If you've got a friendly local owner with the same engine they might let you do a swap test.





Which ECU are you looking for.
Check under the dash on the driver's side - if you want the fuel injection controller - at least that's where it is on a right hand drive vehicle - but, quite seriously, Mitsubishi lists somewhere in the region of thirteen (I kid you not) ECUs on an iO with all the options.
