Hey wassup yall!!! I recently had my buddies convert my rx-8 fully into a six speed :D...But since I converted it the car runs in "limp mode" Meaning it wont let me run the car at full throttle. We ran a obd2 reader and the codes showed transmission shift 1and 2....We changed everything except the wiring harness inside the dash and the key and comp.....I have another ecu with the original ecu for that key we changed it out but tha car just cranks over but wont start. Anybody out there can help my rx-8 stop ruinning at "limp mode" and start running fully....Oh yeah when I first start it up it will drive fine until after 5 seconds the car dumbds itself down Please can anyone HELP!!>????
