@dennyt: Oooh, I like it. An "average mpg since last pushed" button. It seems like that would accomplish what you want, no?

@War_Wagon: Nice. Throttle position would work too, it seems.

@Old_Tele_man: BSFC maps would be hard, since you can't measure the torque output directly. You can interrogate the RPM readily, so the X-axis is nailed down. Theoretically there's some monotonic function that relates throttle position to torque, and throttle position you can get.

@dcb: In my intro post I noted that I have access to an OBD2-capable car (a 1995, no less)
