One assumes that there is "something" going on. What is unknown is what that "something" is :-). If you (or anyone else) has any ideas, I'm all ears. As I said, installed per plans and instructions; both Dynon and Garmin; installed by me and others. The cals don't fail - the magnetometers just...

I wish that were true. I've never had good experience with either Dynon or Garmin's magnetometers from an accuracy standpoint, for either me or my customers. They either drift over time, or have errors in one direction and opposite errors in the other direction. This, after the ground cal and...

You're misunderstanding what I'm describing. I'm not trying to use both systems "at the same time", which isn't possible. I'm indicating when the DEST waypoint shows up, and when it doesn't, and when the VSR works, and when it doesn't. When I ONLY use the GSP-175 as the Flight Plan Source...

I have a 10" Skyview, single ADAHRS, Dynon COM, Dynon SV-XPDR-261, SV-ADSB-472, ARINC-429 Adapter, and a Garmin GPS-175 Navigator. I have two question/issues: 1) When programming the Skyview with a flight plan and a final destination (the last waypoint, obviously), the MAP Info list will show...

What way IS there to upload fuel calibration information to a EMS-120, trivial or not?  I'm willing to jump through a fair # of hoops to do so... Thanks.

I had a very similar issue very recently with an EMS-D120. I started getting short term jumpiness and fluctuations in the EGT/CHT's. Sometimes, putting pressure on either of the two connectors (37 pin or 25 pin) would get the fluctuations to go away, and sometimes it would redline the temps...

I seem to remember seeing something like this when I installed my EMS. IIRC, it turned out to be a loose connector on the back of the unit - I hadn't yet tightened the screws, or maybe even plugged in the wiring harness for the EGT's. You might want to check for something as simple as a loose...

That's fine - all I'm asking for is that it be MY choice, not the device's (in this case). If it's something that the user can set, then you will have the option to leave things as is, and the alarm will go off. I, conversely, would have the option to decide for myself whether or not I want...

I agree, and that's a good thing. Here, I don't agree. I think that there is a way. You're correct - relying on only one signal would not be a good idea. However, there are (at least) TWO signals that indicate a stopped engine - RPM and Oil Pressure (there's MP and FF as well, but they've...

Assuming this works, it should be trivial to do the same at the other end - have it not alarm when the engine is shut down, too. That would be great!

That's true, but the high fuel burns (higher than in cruise flight) only occur for short periods of time, and are a special case. It would be simple to have a setting for fuel flow, above which the alarms would not occur, but below which, they would. You could call it "Climb Fuel Flow", make...

As a follow on to my previous alarm requests: 1) With the fuel flow calculator, we get a nice estimate of fuel remaining at the next waypoint, updated realtime. This is very useful. However, it's perfectly happy to report negative fuel amounts, with no yellow or red alarms popping up, and no...

I'm a new owner of a D120 EMS system in a COZY MKIV. I've got all of 45 minutes of flight time on it so far. Everything seems to work well and I like it a lot, although I still need to tweak some of the alarm limits. At any rate, I notice that the oil pressure alarm (as well as a few others)...
