A friend in Florida rigged up his own non-magneto ignition robbed
from a late-model motorcycle and installed it on his O-200-powered
Murphy Renegade. If I recall correctly he has it set up to advance
itself as much as 35
degrees. Any more anecdotes about nonstandard ignition boxes?

I just completed a similar thing.
An old magneto without coil, points...
I drill the distributor and bolt two magnetic sensor at 90° angle
I made a steel plate in the distributor gear for one pulse each 180°
I purchased a CDI box from M&W (http://www.mwignition.com) and two
coils.
On workbench, I read for 2500 rpm.

Now I have a CDI distributorless left ignition and a magneto right
ignition. Advance is set at 30°, but I think I will set a little more
(33-35°). I may install two other sensors for right CDI ignition.

The fisrt start on friday, 13.
Very nice iddle, very easy start in cold weather... 1st flight within
2 days. A long ground test planed this afternoon for engine and
radios tests.

Wish list: a microcontroller with MAP and RPM advance settings.

My engine: A65-8F
My plane: minicab F-PRAZ
