    If the car is stock, I dont see a point. Other htan it to look cool while it sweeps...

    I would think the main purpose was to tell when a car is running lean or rich to prevent damage. But to get a more accurate reading, you'd need a wideband O2 sensor... somethign that reads more accurate.

    yup, hooking up a gauge to stock narrow band is all about show and really nothing else

    even with a wideband 02 sensor, the gauge is commonly just used for observation during driving

    actual tuning via a wideband is done using a datalogging program

    PLX Devices makes a conversion for the Autometer A/F so it can be used with their wideband as a reader. Outside of that though, it isn't accurate enough to do anything other than look at.

    so basically without some sort of datalogging software an AF gauge is worthless. even with a wideband o2...

    not necessarily. you can glance at it and see if you're about to blow up from running to lean or not-- but that should have been fixed on the dyno :p

    AEM makes the UEGO(or whatever they call it) now.
    wideband 02 sensor, and gauge.

    They have for a while, call them and ask them about using it without their EMS though.
