B6VD will not properly run in a B6V8 application. B6V8 is turbo only, B6VD is N/A only.

Have you looked at your ECU? Is it damaged from the heater core leaking onto it?

I have stock and upgraded computers available if you are interested.

Assuming it is the computer under the center dash board which controls the injectors and everything else that makes the engine run. Unless there are underlying electrical problems I don't think switching out ECU's could hurt another unit. That being said check all grounds to make sure that the connections are good before you start on this endeavor. This is the number one item that leads to this type of problem. Start with the one that is connected to the VAF. Then go around the engine compartment and find all of them make sure there isnít any corrosion on any of the connections. If all else fails let me know I have a spare but I will need a core to get you one.
