Re: Fluctuating EGT's The problem was the fact that the SL30 and the serial port of the EFIS was always connected. Installed a switch to isolate FLIGHT MODE - EFIS to SL30 or UPDATE MODE - EFIS to D9 serial port; and problem solved. :)

Any ideas; I assist at a local avionics shop and we they have the following problem. EFIS D100 DSAB linked to EMS D120 for about 6 months now. No problems with EGTS's. During current visit to the shop added a serial connection between the two as well as connected SL30 and Garmin 296 connection...

I can only comment on the OAT location based on my experience. I originally had the OAT probe installed under the tail section, just forward of the horizontal stabiliser. The effect of the exhaust gasses even about 4m behind the exhausts was at least 5C. This also changes with the relative...

I like to do a compass swing every few months. This has become more important because the heading values are now used for wind calculations and small errors can cause huge problems in the wind calculation. The other value that obviously impact on the wind calculation and that has me thinking...

Hi Kevin, Dynon might be on holiday 8-) For wind display to work you DO need the OAT probe. Setting it manually disables the wind display. Blue skies, fabjab. ;)

I second that under the seat is not a great idea... :-? I have my remote compass in the tailcone and once packed my mobile phone (switched off) in the rear luggage area. That is still about 2ft from the remote compass. In the flight, heading was off by about 30deg and winds indicated about...

Here is one:

Maybe a picture can illustrate what I am talking about a bit better. The plot depicts CHT's while doing 3 circuits. I have also checked the temp on one of those CHT's with a conventional CHT display and different probe, and then the temp was in line with the other CHT's. Always the same 2 a...

To all those clever boys out there; please help me find the reason why 2 of my CHT readings read about 30C higher than the others at elevated temperatures (cylinder 2 & 4), but all 6 CHT's read the same when the engine is cold. I would expect the bank with 2,4 and 6 to be slightly hotter than...

I am helping with an aircraft where the pilot had installed his battery with reversed polarity after charging it. :( Both the D100 and D120 was connected via keep alive power to this setup. Could this have caused any damage to the units or to the internal battery of the D100?

What current draw on keep-alive power should I expect to see for the D120?

The Spruce site shows the probes with the remote electronics at the bottom. Probe is .250" diameter and the fitting is 1/8 NPT. They can make them to custom lenght. Mine are installed in a Jabiru and run from the bottom wingroot diagonally through the baffles to the top outboard of the tank...

I am very happy with the Princeton probes that I have with my EMS. They are very accurate and reliable and installation was straight forward. With remote electronics, they just need to be threaded into the wing. They were made custom lenght for me (43inches) Struggling to post pictures of them...

Do you have guidelines yet on how to wire for flap position and fuel pump ON so long? I would assume Fuel pump can go to pin 9 or 10 on the EMS, but don't have an idea for flap position. Thanx, Carl.

I would also like to second the suggestion to mix units for the EMS. I have mine set as metric right now, but would like to display the MP in inches Hg. Thanx, Fabjab.
