Go into graph mode (buttons 3 & 4)
   Then activate "Track Mode" (buttons 1 & 2)
   Then set the program knob and mixture knob at the 12 o'clock position
   Set  the Mode selector to "0"
   and finally (with the engine running)  press the Store button to start
   the auto-tune.

   Perhaps it won't work is because you don't have the procedure quite
   right.
   Do this with the engine running - The first three steps are correct;
   but you
   then select mode "9", and do not need to press store button.

   So Al how well does this work? Does it keep the mixture constant
   as you change altitude? As you change prop pitch?

Al,
You're correct.  I was going from memory.  I've tried the auto-tune
following the manual and was unsuccessful.  I may try it again once my
engine is running "pretty good".  That is one more thing that I forgot
to mention.  The engine needs to be running fairly well before trying to
get it to auto-tune, otherwise you won't be able to keep it on one map
address long enough for the EM-2 to do its job.  Here again, that's
mentioned in the manual.
