What gauges do you use on your scangauge?

Instant MPG, Throttle Pos (TPS), Volts (Been having battery issues), and Engine Load. TPS and engine load seem to have the biggest impact on FE

The combination of MPH/GPH/TPS gives me the right information to lower my fuel consumption. I used to go 66MPH on the highway. This week, I realized that there's a sweet spot at 61MPH, not below and not above. Interestingly, the throttle was barely on, even with a headwind.
