[SentraSE-R]

Here's how I set my first screen up.

impg and trip average mpg are self-explanatory. I monitor % engine load on my manual xB so I pulse at the best BSFC (about 85% load). I monitor it on my wife's automatic Elantra to keep the torque converter from slipping. It'll stay locked in top gear on hills as long as I keep the load under 70.

I monitor battery voltage in the Winter to keep the battery above 11.6V. Driving with lights & fan drain the battery down. If it drops below 11.6V, I keep the engine running to be sure I don't deplete the battery and lose the ability to restart the car.

My other primary screen displays are timing advance and trip distance. Once my trip mileage gets up around 60-75 miles, I like to reset it so the UG's trip average is more responsive to my driving. Timing advance relates well to impg. The higher the timing advance, the higher my impg.

Next up is my second UG display screen.

This screen summarizes my tank average mpg, distance traveled, and distance to empty. I also monitor intantaneous gph, and engine and intake temperatures.
