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.
