This is the second most important variable you need to calibrate after you've calibrated the speed (VSS Pulses/Mile). I would check the table here:

MPGuino - EcoModder

And find an engine and vehicle that is similar to yours in size. Use that value as a 'reasonable' starting point. This number tells you exactly what it says -- the number of microseconds that the MPGuino will measure for each gallon of fuel that is squirted into the intake manifold.

If either this or the VSS Pulses/Mile are not correct, your mileage will not be correct. The VSS Pulses/Mile is the easiest to calibrate first, as you can just drive 10-20 miles or so and get a rough, but decent, calibration on this one.

I don't think this one is being used by the software currently.

With the released software, the screen will always stay on. Only the backlight will turn off after your timeout in us. The default is 420000000, which should be 7 minutes.
