I am still trying to get my head around
this, Bobby.
I don’t remember if you have a turbo
or supercharger. I assume you are running WOT? I am not running my
rpm that low for fear of “pinging” that I would not be able to
hear. I am normally aspirated but you know how a car will ping when you
climb a hill in high gear.. You have the MT prop so you can control the
rpm, correct?
What does your plane weigh? It seems
that you are really getting great performance out of your install! My
fuel flow is not yet calibrated, but it is not going to get into the 8s from
the way things look now.

Cruise rpm is
typically 1700-1825 prop \ 4850-5200 engine. The low rpm may influence my
EGT’s. In this configuration I see 160-165 MPH TAS at 8-8.5 gph at 6000
foot. It does a little better up high.

Bill,
I see around 1650F
max. At cruise altitude running less than 30”MP I can lean to about
1475F.

The EM-2 mixture is working fine now, Tracy. I appreciate
the rapid turnaround.
I wanted to ask you about the EGTs I
should expect from the Renesis. I am getting EGTs in the upper 17s.
I think I expected them to be a couple of hundred lower than that. I
don’t doubt the accuracy because the EGTs report a pretty accurate OAT
when I first arrive at the hangar and before I start the engine.
I did some relearning of the EC-2 during
the flight today between 18 and 29 inches manifold pressure. This was
done at 2K feet. The MAP was lowered considerably and now the mid point
of the graph is pretty close to the knob center, maybe 12:30-1:00 o’clock.
A good explanation of how to lean would be
very helpful for me at this point. Also I am wondering what fuel burn
most are getting at cruise. I am still calibrating this function, but I
would like to know what to expect if I ever get it right.
