Is there a way to test the ECU that doesn't involve swapping in a known good unit? The reason that I ask is that I'd have to find some with a 5spd, single pop, 740's ECU to test and I don't know a single person to swap with ( might be time to join a local club!!!) Since I live in So Cal, I'll give Greg a call at SZ and see if he could test it for me.
