Hi Bernie,
Just wanted to let you know that on the trip down
to Shady Bend, when I leaned the engine waayyyy back, I get what I refer to as a
"lean miss". This is down around around 5 GPH. It occurs more
frequently the leaner you trim the mixture.
I don't recall the status of your mixture when you
were having the hic-ups but if you were running very lean - it well could have
been simply "lean-miss" and richening the mixture should make it go - a -
way.

Hi Bobby,
With this new prop, absorbs lots more power, that is a possibility but
Tracy and I kinda ruled it out this morning. When I fly next, will try to fly
at about the same conditions and record some data.

Was the engine rpms
close to the injector staging point?

I had the same thought but the scenario is wrong for this. The
"miss" would happen only at full throttle (usually during climb) and never
at cruise or low power if slipping input shaft were the cause. This is
of course based on one example but logically, that is what you would
expect.
I do intend to add data logging to the EM2 & EC2 but in my
experience so far, it would take a VERY sophisticated diagnostic to detect
this type of problem. None of the aviation type data logging systems
currently on the market will do it. The BMW engine controller (and
probably others) can do it however. The listing of engine fault codes
is over 200 pages long. It can detect and log a single cylinder miss
and tell you which one it was. There are probably more
engineering man hours in that controller than I have left to live.

Just a lurker here, but could it have been the shaft in the
psru, slipping and rewelding, as just stated on the threads? Duane
