This is similar to the miss I have had since day
1. I feel it at least every 5 to 15 minutes. When I added dampers to
my manifold pressure lines the problem became less frequent. I hope to
send it to Tracy this winter.
Also, I have the aluminum parts cut
out for a second crank angle sensor for the Renesis.
Tracy, I plan to send these to you for your use in
working out the details to make it work on the B controller.

upgrade?
OK,
Tracy,
Let me know when the
EC2 version is ready. I will try it to see if it helps the
problem. I have not found anything else so
far.

The upgrade is primarily aimed at
the new closed loop and self programming modes. While writing the new
code I noticed that there was a potential for a single ignition or injection
cycle to be missed under an unlikely but still possible series of events
involving more factors than I have room to describe. I do not know if
this is the cause of what you have experienced or not but I went ahead and
eliminated this specific possibility in the latest code. In the 1500+
hours I've been flying the EC2/3 I've felt what might be this missed cycle
maybe 5 times. It does feel like a miss ( not a backfire) and I would
not say it shakes the whole airframe as you or someone else described.
Perception is a highly individual thing though
:-).
The new update is available for the EC3 now but the
EC2 version is still in work and scheduled to be ready in a few
weeks.
Thanks,
Steve. And you did an excellent job of writing
it!
It appears that
Tracy has an upgrade
available now to correct this problem. Is this true Tracy?

Bill,
There is a
mention of this in the archive message titled "Rotorfest 2012
report".

A while back,
someone mentioned that Tracy was working on
a fix that could help intermittent miss problems. I have not found
that comment in my searches. Can anyone bring us up to date on
this? Tracy?
I am still having
the intermittent hiccup that shakes the plane. My wife would not be
happy with that!
