Yeah that link was exactly what i was looking for in the first place.

I can NOT find my ECU ANYWHERE.

It does not seem to exist, i see many differnt numbers on ebay and rebuilt ones etc. but 33920-56B90 seems to be a RARE number, and I cant find one that will work? I tryed a 33920-56B30 from a 93 8V 5spd 2dr but no luck....

I think that the 56B90 is a Canadian market ECU. I would expect a US version to work, have you got a pic of the inside of the ECU? It may be that you just need to move one of the config resistors to get the correct set up.

Mine is on the left. It looks exactly the same as the second picture taken from http://www.kick-fix.com/ECU/ECU.html




The gutts looked exactly the same as the B30 that I tried, except it was a different CPU in it. Everything else was identical.



Looks just like mine...

If you have all the same components fitted/missing then the important factors are the numbers on the CPU which give the firmware revision and the four configuration resistors which are above the CPU. If neither ECU work then chances are that the problem is elsewhere.
