It is obvious that whoever came up with those procedures has no
understanding of F:A ratios, GAMI Spread, or the value of EGT. There is so
much wrong in that short document that it's pointless to discuss it in
detail.

Walter, yes it is sad, but you know as well as
anybody how many people that still adhere to that same
philosophy. You can get a lot
of that same erroneous stuff from some OEM engine engineers. Twenty years
ago I was developing IMSA GTP engines for Pontiac. We were using Cosworth's
electronic fuel injection system. The Cosworth engineer said he wanted to
run "lean of peak" during an endurance race for fuel economy. My response
was....YOU WANNA DO WHAT??? He explained they were successfully running
Formula 1 cars lean, although their oil pressure cooled piston dome cavity was
somewhat unique. <grin>
