Re: 1983 UrQ Ignition Control Unit
Don't assume your friends ECU is dead.
There was a change to the MAC02 ECU that amongst other things included
a revision of the PCB. The two ECU's have different part numbers and I
do not believe they are pin for pin compatible i.e. an older MAC02
won't work on an newer loom and (probably) vice versa (although I
haven't BTDT). I did try my '83 ECU in my '85 and the car doesn't
start, (FWIW Frank Sprongl has also tried this with the same result)
so unless its just a strange Canadian ur-q phenomenon (which I don't
rule out!) what you report doesn't surprise me.
When I have time I plan on tracing the pin outs. If your desparate to
know I could be persuaded to do it sooner rather than later :)
Another data point, I just checked the fiche to find out the VIN
number they changed ECU's and it only lists one ECU part number??? 035
905 383 F. I can check the part numbers on my MAC02 ECUs tonight but I
know for fact they are different!
'83 ur-q Rev 1 MAC02
'85 ur-q Rev 2 MAC02
