FYI, I know Doug knows this, but for anyone
here that might not…
John Deakin (Pelican’s Perch author),
is part of the GAMI / APS triumvirate (George Braly, Walter Atkinson, & John)
…Perhaps not initially obvious from
the message below.
I agree on the excellent course recommendation,
a bit pricey, but indicative of the valuable insight packaged into the course.

Terrence,
LOP starts when the
mixture is LOP of course!
Sorry, for the smart
ass response. There are a number of good article on engine management and
LOP operation written by John Deakin on “Pelican’s Perch” on
avweb.
There is also an
excellent course on engine management given by the GAMI folks called “Advanced
Pilot Seminars” - http://www.advancedpilot.com/
I took it and learned a lot.
The short answer to
your question is that you want to be approximately 50 deg LOP in most
situations and it is best if all your cylinders are LOP to the same degree.

Jeff,
May I ask for a little more detail on when the LOP condition
starts? Do all EGTs have to be LOPP, or is it when just the leanest one
goes? And, how lean constitutes enough to be considered LOP?
