I wonder what would happen if you used a 3.0 ecu? Its the same m103 engine after all.Thanks guys, thats the answer i was hoping for, as graeme knows ive had a spot of bother and i have a definite ecu fault, which i will replace as soon as one turns up (cheap),, ive just spent the night in the garage, took the plug out from the idle control valve (ecu fault) and put a bypass switch in the coolant temperature sender (which increases revs when disabled allowing me to simulate a cold start without an idle control valve!) i like playing
Depending on how much you like the car it may be cheaper to drop in a 3.0 engine and ecu, even if you find a 260 ecu, you wont know if it's ok till you fit it.
A donnor car would be a better option.
