Does anyone know how the SG or UG actually calculate fuel consumption? I asked the scanguage folks & they wouldn't tell me, its proprietary. Since they're not reading injector pulses they must be doing some estimation using throttle position, MAP, and RPM? It seems like you could get it calibrated to give you a fairly close average MPG for a given driving style and type of route, but if you change your style or drive more or less hills, or highway then the calibration could be way off.
