Ok .. I bought a replacement ECU for my '90 N/A .. and I took it in to be swapped out (while it was in the shop for some other stuff) .. but the numbers on the new and old ECUs don't match .. I know the "new" one is from a '91 N/A ..

The old one is: N35118881 079700-2253
The new one is: N350

Can this new ecu work in my N/A? Will it toast anything?

Please give me feedback ASAP (as they're waiting on my response to put the new one in and I don't want to pay labor twice if I don't have to)

Thanks in advance!

89 Turbo N370 18 880

NOTE - If there's an "R" at the end, it's a remanufactured ECU. They
also change the last 3 digits to "881". Example - '89 Turbo Reman. -
N370 18 881R. A remanufactured ECU isn't necessarily bad; it DOES mean the ECU was replaced.

So it looks like you had a remanufactured ECU, and the one you have now is not a CA specific ECU. Im not exactly sure what the difference with that is though. It will work and run the car fine, but Im sure there was some emissions-oriented tuning done the the CA ECU

 

Ok .. Thanks for the help!

If it doesn't work, you'll see me here again .. unhappy .. nay, depressed.

 

It should work.

a N350 will Should work fine in place of a N351, you'll probably even get slightly better emissions.
