Correct, if the DP passes OBD check (getting monitors "ready") then it will not throw a CEL.

The opposite is not necessarily true - it is possible to not throw a CEL, but also not get emission monitor ready.

I have been running fabspeed for more than 2 years and no CEL ever and emission monitors are ready. AA should be the same.
