I'm not saying you might not have hit on a magic combination, but in the last 3 years, and several threads on the subject, no one has figured out a way to truly disable the ASS via Forscan over the long term.
You can certainly buy the wire-in ASS eliminator which works.  Some tuners can also disable it.  And speaking from my own experience and others like 
@st8 , as the battery begins to fail, it will also be disabled.  I have heard anecdotally, that a low oil life indicator will also disable it.
