I live on an airport where there are over 30 flying RV' of various models
(another 8 building). Three different RV guys with Lightspeed units have
commented to me that I need to get rid of my standard Lightspeed coils and
replace
them with GM coils. They did not mention any part numbers. I have started
but
not flown my Lightspeed equiped 360 and everything so far appears to work as
advertised. Klaus has also been very helpful on answering my questions. The
next time I see one of the above RV guys who made the recommendation, I will
ask for a part number and the reasons why. It might be a good idea to check
the
RV builders web sites to see whether they have an archive like Marv'. This
appears to be a understood subject by the RV people.

Mark,

Interesting. Klaus' Plasma III literature claims spark duration through
about 20 degrees of rotation (oscillating CD), >130 mJ spark energy and up
to 40
kV for a powerful spark. However, the ignition coil detailed at
_www.pvl.de_ (http://www.pvl.de/) (english) merely claims >21 kV and 30 mJ
(thanks to
Alain).

How does Klaus claim the higher values? Does the LSE CD system boost the
coil characteristics?

But to Marv's point, the PVL coil primary is .6 ohms and 1.65 mH. What
happens when the MSD coil doesn't match up to the LSE electronics? MSD coil
is
.35 ohms and 4.2 mH. _http://www.msdignition.com/coil_blaster_9_8224.htm_
(http://www.msdignition.com/coil_blaster_9_8224.htm)

BTW, LASAR claimed about 40 degrees of rotation for spark duration and 60
kV.

In any event, my dual Plasma III system works just fine, including the PVL
coils.

PS - For LSE users: There is a service bulletin at

(http://www.lsecorp.com/News/ServiceBulletins.htm)
concerning misfires during starts. It is worth reading.
