It may be reading the engine power pulses. I
had to use a damper to remove the pulses. I use a small can where all my
hoses are connected.

Bill,
I will put leak testing on my list.
Bobby
If your pressure is dancing around with the throttle
steady, I would suggest you might have a leak in the induction system unless
you are right on the point where the EC-2 is switching between
addresses. If the fluctuation continues when you move the throttle
slightly, I would think leak. If you check for leaks, don’t forget the
tubing going to the controllers and monitors.

One or two tenths is not significant (1
map address covers about 7 tenths of manifold pressure) so that could not be
the problem. Several very rough spots is a major tuning
problem.

That will work
Tracy. I don't
think I have major tuning problems but I need to see the map table addresses
and each rotors EGT to be sure. My manifold pressure jumps around one or two
tenths and is hard to hold at a constant setting. The mixture
is manually adjustable to 7500 rpm or 34" + depending on
prop settings. But I have several very rough spots that would keep
me from flying. My manifold pressure ports are located in the super
charger discharge manifold and I suspect they are seeing
pulses.

Hello Bobby,
I can have your
EM3 ready in a week if that works for you. Always remember that
autotune is not a fix for major tuning problems. If there is a
significant snag in the EC2/3 tuning , it means that something is wrong
or that the tuning procedure is not fully understood. Always find out
which it is before flight.

I completed another major
milestone this weekend in preparation for first flight. All I can say is holy
s***. I flew with Alex D just south of Dallas. With the IO-540, 3 adult
males, full fuel and air conditioner we where seeing 2k per minute
climb rates. This plane is amazing. Hopefully my little Renesis at 34"
MAP and 100 pounds lighter will produce about 80% of this performance.
I would like to borrow or rent a
EM2 that has not been installed with auto tune capability for a couple of
weeks. I have an EM3 on order but no firm delivery date yet. I will pay at a
minimum shipping both ways.

DAR inspection hopefully next
week.
