Scott,
"Base timing" has to do with the orientation of the internal parts of the
P-Mag. If you wanted to use it operationally, you would have to mount the
unit at a precise angle in the mag mounting hole. Others on the LML have
reported some degree of difficulty doing this. So, the folks at E-Mag devised a
quick setup method where you can mount the unit in any orientation and then
"program" that position as TDC (with the flywheel so positioned).
This option only became recently available with firmware version 16 so
earlier versions would not have the potential problem and if you do have the
later version you should contact E-Mag for the fix.

I got my shiny new P-Mag installed last week
and the first flight was wonderful.
The second flight, yesterday, was more like
Clark's. The P-Mag reset it's timing in flight resulting in a nearly
total power loss when running on that ignition alone. I had been
running on each ignition alternately trying to compare timing.
I just got off the phone with Brad Dement at
E-Mag. He said that they'd become aware of the problem only about a
week ago. What happens is that the unit "forgets" the timing that is
established by the quick setup method and reverts to it's base timing.
He offered me three solutions to the problem - firmware, software or
setup.
I'll send the unit back for the most reliable
fix.
Mark,
What the devil is the "base" timing? Zero for start up? 20-25
DBTDC like a regular mag? Your experience doesn't sound like a very good
failure mode.
