Tracy,
Am I missing something? My manual says Mode 6 is to
adjust for dissimilar sized secondary injectors. I suppose you could use this,
but wouldnt seem to be optimum. Please explain.
Also, I would suggest that even if not needed
(though I dont see how), having an EM2/3 or EFISM and being able to see the
MCT in real time is invaluable for understanding what's happening with the
engine. In my opinion, when you are flying something as experimental in nature
as this it's not possible to know too much.

That method will work but I would suggest using Mode 6 (if you
have it). Much easier to do and does not require EM2/3 to see where to
make the adjustment.

Bill,
I cant speak for anyone else, but my
engine goes lean when it stages. I know what location in the MCT the
transition occurs by looking at the MCT using the EFISM in real time. I
simply set the first location where it runs on 4 injectors way richer than
the previous location. The next couple of locations gradually taper back
down to a more normal mixture. At this point I trial and error adjust the
rich location back down until the bog re-appears, then richen back up a
little. Its really pretty straight forward with the EFISM - I assume Tracy's
EM makes it equally easy.

Mike,
Judging from the ease with which you tuned out the
staging bog, you have a pretty good handle on how to tune the engine with
the EC-2/3.
For the benefit of the ones of us who are still
trying to understand that tricky little gem, could you give us some kind
of blow by blow as to how you went about tuning the bog out? I am
wondering what you looked for to determine where the problem was and what
you then did with trial and error? to tune it out.

[FlyRotary] engine runup video
For anyone who hasnt had that
first engine run and is looking for some motivation. A buddy visited the
hangar a few weeks ago and shot some video of an engine runup. He posted
it to his website and you can find it here:
This was shot right after I
re-installed my original muffler after the aborted DNA muffler test.
Noticeable in the video is the big staging bog. I had this tuned out about
15 minutes after he shot the video.
