Yeah, it's not a Protege, but close enough. Does anyone have/know the designation (4 letter code) that is printed on the ECU case for a 323 GTX/GT ECU (1.6L)? I had a thread going about this somewhere, but I'll be damned if I can find it. I'm such a noob. I tried Reich Racing, but they're not willing to provide support for non-customers. (blah)
