coupe. . . i'm not sure bout the part number. i tried looking it up but didnt find it. I kno i probably didnt look hard enough tough =/Coupe or convertible? They are different ECUs. I have 2 convertible ECUs available from an 02 GT. If you know the part # (MDxxxxx or MRxxxxx) just post it up and I will check it against the ones I have.
