Thanks Mark,
I found this msg when I was going back thru your msgs looking for your
coolant and oil temps. I didn’t find anything recent and they were
195-193. What is happening now? Also I found where you got an
additional 11 mph out of your cowl flap. That started me thinking…what
did you change from to the cowl flap? If you just added the flap, with it
closed, your configuration would be the same as before the flap…???
I plan to copy your flap, but not till I get my cooling changes done
and see what happens with those before I add the extra exit opening.
Last I heard, you had about 140 hrs. Have you had any SAG yet?

report from Houston
I just ran a separate ground wire from one of the screws on the
instrument sub-panel to the forest of tabs. It makes a lot of sense as
the sub panel is mounted on a fiberglass frame, essentially insulating it from
the rest of the airplane. Who knows how the ground path was
completed. It probably wouldn't have hurt a thing to do the same with the
other two sub panels.

Mark,
I copied the
below from an msg from you last Oct.. Which pin on the PCM did you
connect to ground? The only pin I can find in the instructions for the
PCM that is identified as ground is pin 1 which is called out to be connected
to pin 16 on the Controller? Did you splice this wire to ground or did
you connect a different pin on the PCM?

Keep in mind that I had some data corruption problems similar to Al
Gietzen. It seems to be a problem with fiberglass airplanes, so don't be
surprised if you experience this too. With me, it always happened
while on the ground. Last time it happened, I looked at each of the 3
tables and saw that only one was actually corrupted, so it is possible that it
may have happened in the air, but since I was running above 3800 rpm (and
operating in the upper table), I didn't notice any difference. Nobody
really knows what causes this problem, but I seem to have fixed it by running a
separate ground from the PCM to the forest-of-tabs ground. The thought
was that the sub-panel was mounted on a fiberglass frame and therefore was
isolated from ground. I have not had an episode since I added the
ground.”
