Rino,
I assume you have Tracy's EM or Ed Anderson's
EFISM? This sounds symptomatic of adjacent MCT locations being significantly
different (which causes the surging and the indications you see on your mixture
meter). This was the problem I fought for months blindly until I bought an
EFISM. Now with the EFISM I can see what's loaded and ensure there are no big
jumps between adjacent locations.
When I changed mufflers from my original to
the DNA a couple of weeks ago there were significant issues with the tuning
and the engine wouldnt run clean. The staging point was particularly
troublesome. Took about a half hour to tune this out when in the past
(pre-EFISM) it would have taken weeks. I understand you have the auto tune
feature but still think its important to know what is in the MCT in order to
properly understand how it works.

When this problem started I reset the map table
to original, all zeros. The engine run pretty good at that setting it
makes small adjustments when I set it to auto adjust. So the map table
is set at zero at the moment. The problem starts at a higher rpm than
3800 but I will keep an eye on this the next time I try it.
Thanks
Rino

If the surge takes you above and below 3800 rpm, you
could be looking at two different map table addresses for the same manifold
pressure. How do the two areas compare? When it was running ok
did you get a chance to write down the numbers in the
table?

I did install the new chips to
correct that problem.

Interesting! It could be
hunting for a map address.
I am investigating that for
the service alert.

Rino,
I just noticed that there
is a service alert for EC-3s shipped prior to 6-1-08. When did you
get yours?
Surging could be caused by
the EC-3 hunting for a map table address. Are you quite certain
that this is not related to the map table?

Anyone had a problem with
the Renesis crank angle sensor and had to change it. I may have to
get a new crank angle sensor, but first I want to check with you
guys.
Tracy is
probably gone to Colorado, maybe someone got this
problem before.
I cannot get full power on
my Renesis for takeoff on Controller A. Seems like controller
B works OK.
It is not the fuel mixture,
I tried that. Actually, when the throttle is wide open the mixture
display goes up and down rapidly, from full lean to full rich and the
engine surge.
I had a similar problem when
I first installed and started the Renesis. I had the EC2
controller then and had to get the EC3 to fix the problem. Now it
is coming back to me on the EC3, I think. The problem then was
with the crank sensor, the EC2 could not handle the sensor signal at
more than about 5000 rpm.
I think the problem started
progressively during the last few hours of flight, at first I thought it
was a fuel mixture problem and was trying to ajust for that but now it
is not a mixture problem. Since the controller B has NO temp.
sensor and works ok, I wonder if it has anything to do with that problem
on controller A.
