I think tha's what I've been trying to say .... thanks.  Now, when
you say 'closed loop A/F' do you mean EGO?  And how would you 'learn'
off-stoich conditions (esp. power / rich  and economy / lean), since
the EGO feedback isn't really 'calibrated' at that point (I've assumed
that it would still give useful, if not perfect, data).
