I use primarily pulse, and dwl combined with either dfco or engine on coasting, depending on terrain. I use MAP for acceleration and DWL, and Instantaneous MPG for DWL and coasting. My goal is to keep increasing the trip average mpg so I keep watching that too. I watch mph for a general guide to my speed. Coolant temp is for any adjustments to keep temperature in a narrow range and to keep the the fan off. I tried VE (Volumetric Efficiency) and didn't find it to be useful. I don't keep track of fuel used on a gauge, as I don't drive much except on trips and always fill up in plenty of time. I keep a record of when I get gas and fillups. Instantaneous gallons per hour seems a useful gauge but I've not used it much.
