Changing chain cams out next week ona bike and want to put the original ignition curve back in for start up. Partner brought his cd over the other night and put it in lap top but would not let me pull up any live maps or info. Does it have to be hooked up to the bike for this and does ignition need to be on? Any advice on how to put original map back in appreciated. Never fooled with a Race Tuner b4 and dealer we took it to took 2 hrs just to figure how to load it so no help there. On 04 carbed. Thanks
