Hi, it seems that the Knock tables for the E39 have the axis swapped, or at least the Axis labels are misleading....
Note that the ROWs are set in "Airflow Milligrams" but it indicates the "link" is set for "SAE.RPM"
I found this while setting up a E39_link.ini as I didn't have one. Am I just missing it, or was one never set up? If never set up, I'll upload the one I make if others want it.
