Help me understand the timing advance in the pmag. I have dual pmags on my IO 360 a1a. I am still in phase one with about 16 hrs now. I have been running the pmags with the jumper in or A curve, which is recommended by the book to start with. I am considering going to the b curve, but I don't understand the differences or advantage and the manual doesn't really discuss it.
