So im going to be getting a wideband from speed o hut, my question is i have an auto meter wideband hooked up, can i use the "brain" or computer? or do i have to get a different one? Also the wideband is better than an a/f ratio gauge correct? or is it the same thing? Sorry for the newb questions. im guessing the a/f ratio gauge tells me 10.5 in numbers where as a wideband would tell me with the red yellow and green flashing lights? Thanks!
