Hi Bill, 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!
