Thanks Mark, that clarifies things. I know when I
changed mine it really did change too - marginal improvement.
I didnt know if maybe you have Tracy's EM2
and whether or not it would allow you to see map B. I dont have the EM2. Came
out after my panel was done and I already had a different engine
monitor.
I'll read up on auto tune when I can retrieve
my manual from the airport, but I think the EM2 is required?

Re: EC2 setup
Mike, By me stating "it worked fine", I really meant that
I didn't screw up anything major and that it just possibly ran better than
before I messed with it. ;-) I don't know where to go to see the
"B" MAP, or if it is even possible, so all I can go by is by ear and seat of
the pants. Did it appear to run better than before? The answer was
yes. Maybe it was just my imagination. On a side note, I would
like to know exactly what gets copied from A to B when using mode 9.
Now that my auto-tune is working, I have done 99% of my tuning with
it. If you haven't learned to use auto-tune, do yourself a favor and
memorize the steps. It will make life a whole lot simpler.

Mark,
Me too (manual at airport). I updated my
EC2 in January and the new manual says Mode 9 to copy.
So clarify what "it worked fine" means?
Does that mean that the engine runs more or less the same on A & B after
the copy? Or does that simply mean that you know the data copied
OK?
So far the only person who has actually
answered my question was Dave. Was kinda hoping to hear from Tracy but I
guess he's otherwise occupied ( I emailed him a few days ago).

Al,
My EC-2 manual is at the airport, but I'm pretty sure that
the latest manual says to use Mode 9 to copy A to
B. Following the EC-2 manual, I did that on Sunday and it
worked fine. I know that Tracy made some changes to a few
of the modes. As always... follow the installation manual, and after
an upgrade always throw out the old manual.

Mike;
Mode
9??? Unless your unit is different, copy A to B is mode 2 – and it
copies everything. Mode 9 is for fine adjustment of mixture settings,
and is used for ato-tune in conjunction with the EM2.

[FlyRotary] EC2 setup
I now have the airplane
running pretty good throughout the RPM range on controller A. Using Mode
9 I copied the program to the B controller. I assumed that the engine
would run the same (more or less) on B after the copy, but no... Seems
to be rich throughout the range - to the point of mis-firing, surging,
running rough, etc.... I think I can tweak everything to settle it down,
but is this normal? I assumed there may be differences in the MAP sensor
which would result in a small difference but really did not expect such
a drammatic difference. At most throttle settings I have to turn the
mixture full lean to smooth it out.
Does the Mode 9 copy just
copy the MAP table or does it also copy things like the staging point,
the global injector setting, etc...
If I can get this B
controller dialed in I'll be out of excuses - time to
fly.
