. so i leave it on reg gas. but will it go down to 9.7. so if it reads 14.7 its actully 9.7? sorry im slow at this typ of stuff

What was trying to be said is this:

it will read the same AFR as gasoline;

if you want the correct AFR you will have to multiply the gauge display by 0.665 (obtained from 9.78/14.7);

if you want to avoid the AFR differences, then set the gauge to display in Lambda (learn to think in Lambda).

That gauge does not have a setting for fuel type...

it has a switch for AFR (based on gasoline) or Lambda;

so either you have to either:
- view it AFR based on gasoline (and the true AFR would be what is displayed multiplied by 0.665),
- view it in Lambda (you want to see 1.00 in CL, and 0.86 at WOT).
