I think it has to have some kind of display, and an instantaneous and at least one resetable trip readout, to be a really useful "learn how to drive again" tool.

So at a minimum it:
1. has instant MPG displayed at all times.
2. has trip MPG displayed at all times.
3. is cheap on parts.
4. is adjustable to different vehicles.

Other computable items from injector pulse and speed sensor:
RPM
MPH
Gallons
Distance
Acceleration
Decceleration
Hours
