Dennis,
Glad you are nailing down your problem. I too replaced the wiring in my
mag switches and the mag switch itself but that didn't cure the problem. I
believe my problem is not the same as yours. In any event my shutdown
procedure seems to be working well so I will live with it. My engine starts and
runs extremely well and I do like it even though I believe I have worked on
it more then any of my Lyc/Cont engines on the 13 other aircraft I have
owned thru the years. But then they all take work This group is a life saver
for the many problems that crop up. I live in an area that is pretty devoid
of Rotax engines so the knowledge here really helps.

| Subject: | Dynon EGT D180 Erratic |
One EGT reads in about correct range (+/-) 10-degrees of the other probe, but it
'jumps up and down about 10 to 20 degrees.
I am going to replace the probe's connectors that go to the D180 and if that doesn't
do it I probably will change the probe, but hesitate to spend the money
if it is not really necessary.
Any suggestions?

Let's face it, there are ham handed people in this world who should not be
allowed near fine machinery. The fellow who logged that he "cleaned" the
carbs on the 912 belonging to my customer is one. He put the fixation screw
holding the jet needle in so tight that the screw driver slot just stripped
off its ears when I tried to get it out. Soaked it with PB Blaster for 36
hours and no luck. Chucked the piston in my lathe, touched the top of the
screw with a center drill and chucked up a left handed drill bit. Took
longer to set up than it did for the drill to pull the screw out. As you
can see by the picture the needle is quite literally jammed into the bottom
of the screw. The carb piston, thankfully, is completely pristeen.
Did I mention that I love left handed drill bits?

10 degrees is 0.1%!! That's well below the accuracy of the Dynon
AD converter! Set your low pass filter to more agreesive filtering
and you won't see it bobble.

Rampil, thank you for the suggestion; now my problem is locate that filter in the
Dynon (I guess) ... will have to break out the user's manual...

Well, I don't find anything about a filter in the D180 install or user's manual.
I am not concerned about the numerical accuracy of the indication, but rather the
fact the indicated temperature is jumping up and down while the sensor on the
other side of the 912ULS is stable, perhaps moving up/down a degree or two
at as slow rate while the 'jumpy" one hops up and down continuously .. I could
just disregard it but I keep noticing it and thought to fix it,

Swap the probe with one from another cylinder and see if the problem
follows the probe. That way you know the problem is the probe.
Have you made sure you have good grounds for the Dynon.

Hi Rick,
It wasn't the mechanics fault. These fixation screws have Loctite on them from
Bing and they can strip out if not heated. Once in a while I find one I can remove
without over torquing it, but most times I heat them with a heat gun or small
butane torch. Once heated they come right out.
What were you saying on the other post about Rotax engines, problems and owners?
It usually isn't the engine that has the issues, but not having the proper training
to maintain them or maintaining them on schedule. They are not Continental's
or Lycoming's and treating them as such will only cost owners and mechanics
grief and money.

Dynon considers anything within 15F the same temp. If the EGT, even if it fluctuates,
is 0-20 degrees within each other then it should not be an issue.
