I used to use % engine load but switched to MAP, and make sure it doesn't go into open loop, which is a little hard because the foot throttle is not easy to attenuate.
Sometimes I have used 3 screens on auto every 20 seconds, and just change the trip miles to something else, for example battery voltage or bank 1 oxygen sensor 1.
I'm just figuring out that I can use manual screen change with the down button, instead of auto, so I can switch to a more complete second screen just periodically, instead of having them change automatically. Normally though I just use the one screen.

I guess it's vehicle dependent, but are these gauges the best to use to provide feedback for increasing fuel economy other than the instant and average MPG??
Also, how much of a difference does enabling VE (Volumetric Efficiency) make in terms of fuel economy accuracy??
