Hi,
I have some questions on tunning the FTC-1. I have recently purchased a OBD-II tool and it works, but I have no idea what any of this stuff means....the LTFT reads -2.5 all the time??? how can I change any of this. I can go into the fuel map in the FTC program and change numbers if I want, but I have no idea what this will do, or even what it is supposed to do. I have searched all over the board for a straight forward (made for dumb asses like me) guide to tunning this FTC the best I can on my own and the only thing that I can ever find is make sure the LTFT is zero in closed loop??? how do I accomplish this?? there is also something about an AFR of 12:1??? again, where do I pull this info from and how can I get it there? I realize I sound like I have no mechanical ability what so ever....sounds about right....if any one can help I would appreciate it...I only have numbers in my A map and nothing in the B map. Thanks
