Any Advice on Using a ScanGauge

[michaelburke]

I have improved mileage quite a bit since I started using a scangauge but I have no idea how to make use of the LOD or MAP readings to improve mileage. My basic question is how much and when is acceptable? Should I stick to the instant mileage readout? Right now I have mph,gpm,mpg,rpm as my readout. I like reading the mph on the dash as it is more precise and I can keep my eyes on the road easier. We have a couple of "no tolerance" areas in town where 31mph in a 30mph will get you a ticket. I also love the miles left and gas left in the tank read out. It is insanely accurate. Usually within .2 gallons, sometimes dead on. That means I can decide if I have enough gas to run the errand and fuel tomorrow or if I am getting too close to mess around.
