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.

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.
