Re: How do you fool an auto ecu?
Talk to NZ, he's done it. You will need to fool the ECU with the V8 as they have some sort of torque limiting mode to protect reverse. When the ECU doesn't know what gear it's in, it assumes it's in reverse. As a result first gear and a bit of second are gutless. Half way through 2nd the ECU figures out it's going too fast to be in reverse and removes the limiter, but 1st is still a piss poor effort apparently.
I believe even if you found a 5 speed ECU, the extra Fairmont goodies don't like it.
