    Anybody have the Auto Meter 9100 MPG Gauge?
    I would love to have one for my 2011 Tacoma to watch the gas mileage as I drive so I can adjust my driving for the highest MPG possible.
    Do they work, or are they a scam?

    I'd say save up for the Scangauge II. I have mine set to display current and average MPG in two of the display locations, and a couple of other gauges I cycle through on the other side.

    anyone know if those things are accurate? I have a obd2 blue tooth deal and it doesn't give me accurate numbers. They're consistent, but not accurate. It seems to use the weight of the vehicle to adjust accuracy.. doesn't seem too accurate. Which is a shame since everything else seems to be great.
    Also wants engine size and all. Seems a little guessy to me.

    My oem mpg meters were always more accurate than the probable error in volume when filling. Always within a tenth or 2. IT also doesnt recognize that the truck has a DFCO program. Would be a shame if the truck actually didn't but being a truck it may be able to get away without one and american version of toyota being the american version of toyota.....

    that's the thing.. info's info we have the same thing... an obd port. I'm using free software, I can get the source and figure out how to fix and re-compile it.
    But if there's info missing from the obd that scangauge has researched to get a good average...I can't top that.
