ECU EPROM QUESTION... will it work?

[Cheks_Talon_TSi]

I have a 1991 TSi FWD Manual trany and a friend of mine is parting out a 91 TSi FWD Automatic Transmission... his car has an EPROM ECU, will that ECU work on my car???

I believe the ECU has nothing to do with the transmission but I am not sure... can someone help me with this question...

By the way, does a 1G AWD ECU will work on a 1G FWD???

I will apreciate a lot your feedback

What are my Option: Here the way i see it.

Option A: Try to modify my stock FWD EPROM ECU to work properly on my AWD setup.
Option B: Try to find a AWD EPROM or Non EPROM ECU that will work properly on my AWD.

Anyway if any body see's another way out please let me know. And on another note i pull'd my ECU apart and found that i have the R130 resistor installed but i cant find the R129 resistor any where could it be on the other side of the ECU. What would happen if i pull the R130 resistor out.

In '95 the MD312464 was used in both FWD and AWD cars. If you have one of those you shouldn't have to do anything.

The R129/R130 config resistors are 1G specific. On the other 2G ECU's you might need to disable the speed limiter between the two versions http://www.dsm.org/how-tos/speedlimiter.htm

I got the MD309947. What do you think should it work also or not. Thanks for all the info.

Yes it will work. You will likely have the speed limiter but unless you try and go over 130 mph you won't notice.

Well it does work with my stock ECU but not as it should. Ever thing works just fine untill the car heats up to its normal operation temp. After the car heats up it dose not run as good. The temp on gauge is the same as it was before the swap.But before i could pop the hood after runing the car for a long time and pull the oil cap and it would just be warm as to now its to hot to touch. Its like the engine is trying to work harder because of the AWD but is not geting enough fuel or air or something from the ECU. The reason i say this is cuzz few years ago i work'd in a body shop and, one guy brought in an A4 AUDi on which he swapped out his manual tranny for an automatic tranns and his car would over heat becouse of it and, just would not run right untill he swap out the ECU. Damm i wish i had an AWD ECU to test my theory. Also does any body know if the ECU's are interchangeable between other 2G's from 95-99.
