    Figured it out, I had to add the MAP values manually in the virtual VE to see those calculations, mine was only showing to 105kpa until I added the ones above that.
    It seems weird that the VE airflow would drop when MAP pressure and RPM stay the same, VE airflow is essentially a look up table (but not exactly since its based on calculations from the coefficients), so you would think that regardless of whatever else the ECU is doing that VE airflow should remain true to RPM and MAP.

    Kinda my point haha

    One seems to think think theres a hard wall limit when in speed density only mode using the VVE table for fueling at 255kPa being the cut, but it does it around 240 some kPa actually. it goes past it in MAF mode however...
