    VCM Spark Control: Lower only?

    The VCM spark control 'raise' button is greyed out. I only have the option to lower it. Do I have something set incorrectly, or is this by design?

    Its the qay gm did it. Not a bug
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Figures.... Does the 2.5 bar OS allow this Bill?

    I ended up just raising base about 15 deg, then walked it down, so it's not a big deal....
