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).

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).
