    Sorry I first misread and thought it was psi for the carb version.
    Okay now I'm with you.
    2.2 bar = 32 psi
    2.7 - 2.8 bar = 39 - 40.5 psi
    3.2 - 3.4 bar = 46 - 49 psi

    The 912iS Operators manual numbers. page 2-3 under fuel pressure.

    Max is 3.2 bar (46.5 psi) and minimum is 2.8 Bar (40.5 psi). So you may want to make an adjustment in your menu. Something like 2.8 Bar for red minimum and 3.2 or 3.24 bar 46.5 - 47 as high red. I don't know if your instrument has the extra decimal place past the tenth.
    This means anything between 2.8 - 3.2 Bar is green.

    Do these numbers look better to you? What I have been seeing in the field with my customers is 43-46 psi for everyday operations.
