Jeff,
Very nice reporting on the methodical testing that you have been doing on
the P-mag timing. Noting oil temperature, CHT, EGT, MAP, etc. does provide
lots of info. However there is one parameter that you have not noted: What
is the mixture setting? A Mixture Meter would instantly tell
What would also be beneficial would be to open up/control the airflow on the
barrel section of you cylinders (short steel fins) as this has a direct
impact on oil cooling.
Paul.

Have you considered the oil tank shrouds they used to fit to Cessna 120-140s?

Go to page 8 for the tank shroud description.

Emag/Pmag uses manifold pressure and RPM to determine the spark advance
depending on which ignition profile is selected. ?Manifold pressure tells it
how much you are asking of the engine, so when you throttle back or are at high
altitudes, the manifold pressure is way down and the ignition will

Your post begs the question: How do it know we "fly throttled back or at
