From the manual: 0 volts is equivalent of 100% lean fuel air mizture and 1.275 volts is 99.2% rich fuel air mixture. Bank1 is the cylinder bank with spark plug #1. Typically only two O2 sensors are present, one on each bank.

The instantaneous MPG goes to 999.9, and the O2 sensors go to 0.000 when decelerating to 1000 rpm. I like the instantaneous MPG. It's a very nice feature and more stable than expected.

Trip MPG disappeared when the key was turned off and to R, but showed up when I turned the key back on later.
