Definitely looks interesting.

Take a look at an MPGuino fuel economy gauge.

Especially needed for a VX engine with lean burn capability. It measures FI pulses directly at an injector. ScanGauge instead assumes stoich, and then derives an interpreted fuel qty from the air flow sensor data, and the computer's open/closed loop status. So a VX or HX with a variable air fuel ratio (or any engine with do-it-yourself fuel mapping) will not get a correct fuel qty measurement on a ScanGauge.
I still use my SG for other data that it gives very well. System voltage, coolant temp, throttle position, and lean burn status. Sometimes I'll use it for other data as needed.
