I'm using the bottom bar, which start in green and finish with red. And sometimes I use the air:fuel ratio gauge that start with 10:00 and finish with 19:40.Really what I want to know is if the engine is rich when is in green and lean when is in red.
Thanks.

Green is lean, red is rich. The switch point is 14.7 to 1 if you have MS set up for gasoline.
