Engine Monitoring Systems: Are they all the Same?

Monitoring your experimental aircraft's engine used to be done with analog gauges: RPM, temperatures, pressures and the like. Now, with new electronic displays, monitoring of vital engine parameters is done with EMS (Electronic Monitoring Systems) from a variety of vendors. This video looks at an important installation distinction you should understand before choosing one of these models.

i like your video, im still figuring out what displays ill put into my verieze, im using a continental 0-200 and that is a very popular engine should have a lot of equipments that will work with it.

Voice of experience here: We have the MGL Xtreme EMS fitted. The RDAC is in a sealed box rather than open as shown here and is mounted on the engine side of the bulkhead. It took us two years of chasing a temperature reading issue (EGT and CHT would instantly jump into the red, reading way too high) to finally get it sorted. To cut a very long story very short, directing a cool air feed onto the RDAC sorted the issue. It now runs totally stable.

Good afternoon sir, thanks a lot for this informations,
Best regards

Jhon You are good thanks for all the info you provide

Wow the MGL miniEFIS does darn near anything in a tiny package. I mean I guess they all do these days, I'll be looking at them in more depth. Thanks for the video.

I love it!!! ' There's no time like to get back to building!!!!' LOL...

Good vid thanks but I agree with Ron Allen on the canbus comment
Good thing about using can bus you daisy chain each connector, this gives massive scope
Eg I am installing MGL iefis and ems into my build can bus 1 has all the info modules ahrs, compass etc wth 5 connectors running of.
Canbus 2 has a further 5 connectors feeding iefis ems rdac ecb ibox etc.
by keeping all the daisy connectors the same pin outs then the whip cables are made to match the modules it’s easy to change out any component, all you need to do is make a new whip to plug into the daisy chain connector to feed the new component

I agree with Michael Tucker. Screw terminal connections are Pre WWII technology. They aren't used on modern avionics, due to the increased likelihood of a future failure of the connection point. While this connection method offers ease of installation, it does so at the cost of future reliability. Doe the MGL system offer strain relief for the wires going to that terminal [RDAC] box? Perhaps via the cover mentioned by Rob Pritchard?

[michaeltucker]

My first thought on the MGL screw-terminal approach: does engine vibration result in the terminal block screws loosening?

Do you have a video showing the options to install ADS-B ?

[abdaleali]

Useful video us usual, 5:18 where can I get all this instrument

What is your take on the reliability of your MGL EFIS? Have you had any problems with it? I am interested in the AI (aerodynamics only) no engine monitoring. thanks in advance, best regards.

How is that RDAC sealed from elements? Seems you would at least want a splash cover.

You forgot to mention can-bus which is used by Garmin and is the standard used by most commercial aircraft installations.

Here is another engine monitor. This one is very simple / yet modern
