As for the ignition, it is doing fine, now that I figured out
   what was
       causing my misfiring condition at high rpm (6500 & up).

       Other than that, it flies great!

       Mark,

       Sorry, I must have missed the info on your ignition problem.  What
       was the cause and solution to your high speed missing condition.

       thanks, Joel



Joel,
A little history on my ignition problem.  Originally, it was using the
old style CAS, the one that resembles a distributor.  I had the idea of
changing over to the new Renesis style (fewer moving parts, 2 lbs
lighter).  So, I purchased the necessary parts and did the conversion.
I had to send the EC-2 back for upgrades anyway, so it seemed like a
good time to have Tracy change it over.  The mods included the snubber
upgrade to solve the injector dribble problem.

Well, when I got it back, it ran beautifully in the lower rpm range, but
wouldn't run in the upper ranges.  We ended up installing a zener diode
circuit and played around with resistor values until we got it running
much better.  This is what another Renesis builder did and it fixed his
problem.  Anyway, I thought we had it handled, until I started doing
fast taxis and I got into the 7000+ rpm range.  The misfire was back.
Many phone calls to Tracy, and after trying many, many things, none of
which helped, I was ready to change it back to the old CAS.

The last thing on my list of things to try was the CAS bracket.  Why the
bracket?  Well, I remembered reading in the Renesis manual on CAS
information and they mentioned to beware of metal filings/powder on the
CAS.  I got to thinking that if it was that sensitive, maybe my 4130
bracket might be causing the problem.  So, I fabbed up a bracket out of
aluminum and tried it.  Would you believe it, that was the problem.  It
runs great now and I couldn't be happier.  So, if you decide to convert
to the Reneisis CAS, make the bracket out of aluminum, not steel.

So, now you know "the rest of the story".

snips... info later

Thanks,
Mark

Thanks Mark on the CAS steel bracket bit. Amazing. Who would have thunk? :)
