What are you looking for? What kind of ECU? There are many variations, and the car it came from matters- Turbo or non-turbo, AWD or FWD, auto or manual, eprom or non-eprom, 90, 91-94, 95, 96-99 (actually, I don't know if they're all the same or if there was a change in 97-99, but whatever). Specify the car you need it for and you might have a better chance of getting answers.
