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.

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?

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. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404143#404143 ________________________________ Message 6 _____________________________________ Time: 07:15:21 PM PST US Subject: RotaxEngines-List: Re: Dynon EGT D180 Erratic From: "JohnF" 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...

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, Read this topic online here: http://forums.matronics.com/viewtopic.php?p=404152#404152 ________________________________ Message 8 _____________________________________ Time: 07:44:09 PM PST US Subject: Re: RotaxEngines-List: Dynon EGT D180 Erratic From: Richard Girard 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.

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. -------- Roger Lee Tucson, Az.

If the EGT, even if it fluctuates, is 0-20 degrees within each other then it should not be an issue. -------- Roger Lee Tucson, Az.
