In the marketplace....
The magneto remains a very intelligent
and viable choice for most GA missions.

Right, but for better value ratio, I choose automotive CDI box, two
coil and I have a distributorless ignition ready to fly for ? value
of a new magneto.

I have two non shielded AM4 eisemann magneto and I don't realy want to
purchase a new Slick magneto neither a used Bendix.
I need to upgrade with EMI friendly ignition, a set of new magnetos or
electronic ignition from automotive parts. When I check noise on my
handeld VHF very near my car ignition, I find it is realy quiet.

I choosed and I will begin to flight before you wake up to morrow.


Against EMI emission, I choose resistor plug, resistor caps and
resitor cable. The radio is now clear of EMI emissions from ignition,
now I can install a fixed radio and a Xponder for busy aeras.

It is the first goal I acheived, the second is a little more fuel
efficiency, I need more range, and I think it's better to burn less
fuel than to take more fuel in a bigger tank. I work with the CAFE
and EAA printed reports about ignition during the '90s.

With this reports, I think it is possible to set more ignition
advanced (38-40° btdc) on full throttle for 65% power on altitude and
run leaner engine .

For engine controls I use an engine information system with 4EGT and
4CHT..... and flight engineer knowledge....
