Hi all, so my problem is that we have a 1989 mustang that we swapped over a motor from a 85 Merkur, now we got everything running, just the ECM that is in the car is a 8CC and doesn't know how to correctly run the motor. So we have the ECM from the Merkur, we just don't know the strategy code behind it as the label is completely worn off. And after doing further research on it there is only two Merkur ECMs one is a PF2 and the other a PF3. Where I need the help is how can I tell the two ECMs apart without having the label?? Thanks a ton.
