I had a New Yorker that had the digital mpg guage. The game was to pop it in neutral and see how long you could keep it at 99mpg while coasting.

I don't have one in my car?

Anyways I wonder if it does work off vaccum? All you really need is the flowrate of the fuel which can be approximated by the injector pulse width and the speed from the vehicle speed sensor.
