no, a 90 nt would not would not work in a 92 tsi. Fuel, timing, Boost, and vaccum would be way off. I think the wiring is diff from a 90. I believe you can get any 91-94 turbo ecu. Auto doesn't matter though.

[fasttom]

so it makes no dif if the computer is out of a 5 speed car and is going in a auto? i am asking cuz there is a post going in the basic tech.
Thanks!!

On turbo cars with MT, you will need a MT ECU.

the car i am buying is a 92 tsi awd with an auto in it i want to know if a ecm our of a 91 2.0 turbo fwd with a 5 speed well work

It will be off slightly, but it would work to limp it around. The car will run a little rich and the timing would be off a little. Nothing huge, but I wouldn't want to run it like that for any length of time.

I fucking already said it won't. Please don't ask questions that have already been answered. It won't work well for a few reasons...mainly different injectors and turbo on the 1G AT cars compared to the MT 1G's.

The turbo makes no difference to the ECU, but it will run about 15% rich. Like I said, it will run, but I wouldn't want to run it like that for long. At cruise it should be able to fix itself because it checks the O2 sensor, but at WOT it will be off.

Oh ok...so you shouldn't have to retune your car this summer with your larger turbo :stick:

Auto cars have different cams, turbos, and injectors so it will be off. I don't know what the hell I was thinking above... Any 91-94 turbo 5-speed ecu will work. It is FWD and AWD that is interchangable. Search junk yards on car-part.com.
