Do a search on "scanguage" and you will find multiple threads on it. I had started at least one thread on "scanguage", and know that I replied to at least one other. Yes, I think it is one of the greatest, most interesting, tools available for OBDII vehicles. Just do a search.
Its a guage, similar to other guages in the dash, to be glanced at like any other guage. Its not meant to be stared at, transfixed or hypnotized by. Of couse mounting is the key. It comes with velcro strips to mount anywhere, and I have mine mounted on the dash. But if you prefer a red light to flash in your periferal(sp) vision to indicate trouble , thats fine with me. Give me more info, and I will sift through what I dont need.quote:

Yea I should have been able to figure the battery voltage outquote:

I'm not sure what any of that has to do with the Scangauge. EDIT: I see you're talking about the competing product.
The Scangauge measures battery voltage directly--it doesn't get it from the PCM.
I'm not quite sure how the Scanguage measures fuel consumption, but I can assure you that it doesn't do it by measuring fuel tank level. (The fuel tank sender in my 1996 Ford Contour isn't connected to anyplace but the instrument cluster..the PCM has no idea how much fuel is in the tank).
It also puts an engine displacement coefficient into equation. I had to fine-tune my ScanGauge "engine volume" setting to match my consumption measured at the pump.quote:

I think it calculates MPG by measuring the amount of fuel injected, based on injection pulse width and engine RPM and engine load and mileage traveled.
Injector information is not available to a non GMC vehicle and even if it were injector sizes are different. I'm going to email/call them to get the story. Even though I have an OBD-II I'm thinking of buying this bad boyquote:

OBD2 cars have a "VSS" (vehicle speed sensor) that operates the speedo and is used by the PCM to control engine operation. I think it calculates MPG by measuring the amount of fuel injected, based on injection pulse width and engine RPM and engine load and mileage traveled. My Scangauge seems to be OK as it shows the MPG that I know it delivers. 20 MPG at 70 MPH with 2002 GMC Sierra with 5.3.
