I know these arent very acurate. Like what light indicates 12-1 a/f ratio. Or is that number to low to even register on the gauge.

 

There is no way to tell what light equals what A/F. You need diagnostic equipment to tell you that. I will tell you this though, 12.0 is not too low.........as a matter of fact at WOT my race program was at 12.0..........and my gauge was green the whole way down the 1320'
