    VVE MAP / Baro Pressure Ratio Logging Help

    So i am having trouble logging for my VVE table to dial in my tune as i have MAF disabled to dial it in.

    Named it Pressure Ratio
    My math parameter is [50030.90]/[50032.90]

    50030 MAP sensor Unit Pa
    50032 Barometric Pressure Unit Pa

    My graph is setup as:
    EQ Ratio Error [Math] (from lambda & AFR table )
    Unit: %
    Decimals: 2
    Cell Hits: 3
    Shading: 20 High 0 Low
    Column Axis: Engine speed
    Unit: RPM
    Row Axis: Pressure Ratio
    Unit: (blank)

    I have copy and pasted both axis from the VVE table but my cells are all blank when trying to data log. Please HELP!
    Also doing this on an ATS-V

    Do you have Engine RPM, MAP, Baro, Wideband, and commanded AFR (or whatever unit you?re using) all in the channels list?

    Yeah, which is why i am just not understanding why it's not logging. Was hoping i overlooked something easy.
