Dr. HSU, oh ye of little faith... I do suggest you look into the "SDS CP1
electronic ignition systems". It means that I have dual independent power
sources for controlling each independent timing computer with automatic
customization for RPM and load (manifold pressure). The computer monitors my
manifold pressure and smooths out the engine timing to give you the best engine
performance on your climb or cruise. You are always one set of points or
capacitor failure before your engine goes to hades... (you know "Hell")...
Consider this"1. The engine timing with an electronic ignition system does not
drift from the setpoint since there is no mechanical wear and tear2. Each
independent computer controls an independent bank of spark plugs (4 upper and 4
lower)3. You can customize the power curve so as you climb, the computer
compensates by adjusting your engine's timing for the best performance. 4. Two
completely independent batteries, one acting as primary, and the other as
backup.5. No mandatory 500 hr overhaul6. No moving parts in the whole system...
none7. Each computer is capable of advancing or retarding the timing of your
engine for best economy or to prevent detonation based on manifold pressure. 8.
Lean of peak adjustments extracts all possible energy from the fuel, picking up
a few extra knots which are lost running leaner mixtures.9. Low current draw,
long spark duration, 4 cylinder coil pack and controller draw about 1.2 amps at
2500 RPM.
and there you have it...

No magneto anymore on your bird, Luis? Well, I understand you may have dual or
triple SDS Electronic Ignition, but it's NOT the same as far as reliability is
concerned!!! I would much rather use a redundant ignition system each with
completely different design. Think about what's going to happen if you were to
suffer from a loss of electrical power event...?!

I have dual SDS Electronic Ignition, no magneto. I removed the D3000 Dual mag.
I had sent it off to be overhauled and when I got it back I had second thoughts
about using it. So I spent the money and bought the electronic one... I love it.

Congrats Luis!
What are you using for ignition?

Indeed Roger! It hurts really badly just to think about how things could
suddenly be turning straight at a 180 heading in just a bit over a year and
half.... !!!
Frankly, I had to put my flight training on a temporary hold due to the soaring
100LL fuel cost since early this year. Perhaps, it's time for some of us to
start thinking of converting the KR2 into a first ever e-KR2?! It will be a
huge success and historical significance if someone could manage to complete
the 1st e-KR2 conversion and keep it in the air for 30 minutes or longer?!
Seriously, if anyone wants to embark on this challenge for an e-KR2 conversion,
please include me in the team and contact me for a "secret" type of battery
that weights less than 15 lb (as compared to 33lb of a same capacity Concord
12V 330CA), and zero leakage on voltage after installed on my Piper PA-28 for
two years with a full initial charge...! My Piper starts every single time with
only one cranking regardless at -15F in the winter, or 110F in the summer ever
since I took it down and throw the Concord battery in the recycle tank!
Best of luck to all!
