I happened across this post on Robert Paisley's EFII site a few weeks ago. I appreciate his thorough explanation and comparisons. looks like a good unbiased test.

What I don't understand is why does the Lycoming seem to run smoother on LSE when the mag is switched off and I'm running on the LSE only. The graph seems to suggest otherwise with output and spark duration of a mag proportional to RPM compared to LSE. Even at 1700 for a "mag check" one would expect a smoother engine on the mag let alone at 2400 rpm at altitude even with mag fixed advance given this data. Is it a function of spark plug type more than the output of the energy source? (Massive electrode vs. auto type)
What am I missing here?
thanks,
