Is a fwd and awd the same?

As far as ECU's go... yes.

You can put your '92 FWD ECU into a '93 AWD and the car will not notice the difference.

The differences are from the '90 ECU's, the auto ECU's and the turbo vs. non-turbo ECU's.

But you can put a turbo FWD ECU into a turbo AWD car without a gltich.

Hope that covers most of the bases there.

thanks, I was pretty sure that's how it went, but rather be safe than sorry.
