So,
Suggested procedur= e is to check mixture at about 23 - 24" Hg MAP.  Adjust Mode 3 for m= id-scale mixture on monitor with mixture control at 12:00 if necessary.&n= bsp;  Then start programming at lowest MAP (idle) using mode 1 and w= ork up in 1/2" Hg increments. 

If this does not give satisfac= tory results let me know.
