[Vincent Frégeac]

Working with the delta between expected and actual is the definition of
"closed loop" controllers, which is any controller with a sensor for
what it controls. "Fuzzy logic" does a bit more. It react to this gap
once and "remember" what happens so next time, instead of trying
different parameters, it will apply what it learned from the last time.
Moreover, if it learns from two set of conditions, it can deduct what to
do in between these conditions. In fact, in any application when you
can't program all the possible conditions, a learning "fuzzy logic"
controller is superior to a classical binary logic programmed
controller.

BTW, I'm thinking that, as we have to reset the Motronic to erase what
it has learned, there is a good chance the Motronic includes a "fuzzy
logic" part for this "learning" process.

My 0.02 cents of experience in fuzzy logic and other controllers, no
BTDT in engine control though.

Pastore...  The delta between map and desired boost could be the danger
zone 
by definition.  The way I understand these machines in learn mode is
that the 
map is looking for flutter vs desire, which is an indication of surge
line by 
definition.
