[DML] Re: Disabling Lambda



It's rather unusual for the Lambda ECU to fail. I submit the original problem still exists that caused you to believe the original ECU failed and is now causing the present problem. You need to fully troubleshoot the Lambda electrical system. The way the PRV-6 is set up in the Delorean requires a working Lambda system. You will not be happy with things just by enrichening the fuel mixture to make up for a non-functioning Lambda. Is the little ground wire connected to the intake manifold on the front, right side near the frequency valve?

I'm really trying to understand why I should buy a 30 year old, decaying computer module that is probably just going to fail soon after purchase.
