Would really like to here from anyone who bought the Gothspeed dummy bypass specifically to eliminate OBD code 1448. Image Unavailable, Please Login I have spoken to SkippR who has had continued success, but would appreciate anyone else who can provide some info. And if Santa does exist, perhaps someone knows exactly how it works? Does it simply send a single fixed output voltage to the ECU, or maybe sends an oscillating signal to keep the ECU utterly confused.....lol
