I just installed a new P-Mag on the O-320-E2D (low compression) in my Lancair-235/320.  Followed the instructions and all ok on the first-start and engine run-up.  Will finish buttoning up the cowl in the morning and looking forward to my first flight on this type of electronic ignition - had rotten luck with Lightspeed Plasma III, so hope this one works out.  If so, will replace my other old Bendix mag with another new P-Mag.

 

The installation included the jumper to make the timing the "A" schedule.  Any advice/cautions about running the timing on the "B" schedule?
