Ken, your missing the main point of my message.  This "black box" would
adjust the O2 computer in REAL TIME according to the input from the O2
sensor, not just feed the O2 computer say a constant 1.1V.  It would be a
simple transistor with user adjustable gain.  You're right when you state
that the mixture would change under load, the O2 sensor will pick that up
and send it to the computer.  If the "black box" is in the way it will
modify the signal in real time...

Of course all this is a theory in my head which is too full of theorys and
not enough time to do something about them!  :)
