    Default SOI Calculations

    Maybe somebody knows exact formulas or something with which I could calculate SOI for 90 mm3?
    Also would be great for fuel pressure too...
    Thanks in advance

    I think you want to know EOI:
    EOI=SOI-rpmx360/60000000xIOT

    Example:
    rpm: 4000 rpm
    IOT 826 us
    SOI: 20,8 deg
    EOI 0,976 deg
    0,976=20,8-4000x360/60000000x826
