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?

Bill,

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?

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.
