    Scanner Speedometer>Wheel Accel Decel PID?

    What is this PID? :huh2: I hadn't seen it before. I'm hoping it's something
    that would be usable for logging vehicle acceleration (like an in-car
    G-meter). But what is its action, its units-basis, is it a single wheel or an
    average (perhaps to be corrupted by wheelspin) etc.?

    Anybody?

    What are the units for this parameter?

    I'd like to see the differential of vehicle speed, and I was hoping that this PID would help me, as the transient modifier (dy/dx) doesn't seem to work as I had expected. Any clarification on the meaning of this PID? I notice that there is no way to select the appropriate units for acceleration (e.g. mph/s, m/s^2), so I'm thinking I may be misinterpreting what the PID's purpose is.
