StevenL, what is the instrument below the GTN 750Xi in the photo of your prior panel? A GTN 650Xi or a GNC355 or something else? John.
 

You had it right…it’s a 650Xi.

Any reason why you wouldn’t put a G3x for the engine monitoring instead of the EDM900?
 

[IFLYIFR]

If your engine instrument indicators are on the G3X and it fails, you also lose your engine readings. The engine data will display on your iPad if you use Garmin Pilot but not if you use ForeFlight. The EDM provides a separate independent way of seeing the engine readings regardless of the operation of the G3X.

Thanks for the response. I was thinking to have a G3X on the right hand side which primary purpose is EIS. It seems cheaper than the EDM 900 and has flexibility for doing more should you want it to? Am I missing something?

thx.

Fred.

I do not have a G3x but I have specifically asked Garmin about the G3x and engine instruments. Garmin said if you have the engine instruments displayed on a second G3x then you will not lose your engine instruments if the PFD on the left side fails. This point is included in one of the paragraphs on the Garmin G3x webpage. John.

A lot of cool panel images in this thread, all of which I like. I just finished something similar (photos attached): G3X, GTN 750, GI 275 (2), GTX 345, GMA 350, GFC 500. One thing not apparent is that I got the AOA indicator, too, which will display on the G3X. Still need to calibrate that in flight.

Regarding the EIS, I'm happy with the Garmin, so far, but if I were doing it again, I would consider going with the separate JPI. Regarding G5 vs. GI 275 , the avionics guy I worked with thought highly of the GI 275 and its suitability for my setup, so that tipped the scales for me - I didn't research that piece much on my own. Regarding the placards, after seeing the comment above, I need to go back to my POH and verify they're all there. 

I wanted the radios stacked with the autopilot on the bottom, but there was some clearance issue with my setup that prevented that. I had an SL30 nav/comm slim-fit that I sort of wish I had keep in there, but I kept the GNS 430 instead thinking I can replace it with something newer and standard sized at some point.   

The quoted 6-8 weeks for the panel work turned into four months, which I attribute to too much business and too little labor at that shop; they juggled work and planes. It was annoying, but I never really expected them to hit the lead-time.

@Brent, I may not have seen the most current G3X installation manual since Garmin doesn't make those available, but the one I reviewed (rev 7, 2020)  had a number of limitations on the GI 275 when used as a standby for the G3X, and I'm curious if any or all of these still apply:

1. The GI 275 has no interface to the G3X system

2. The G3X system and GI 275 standby instrument cannot share the same GMU 11 magnetometer and  GTP 59 OAT probe

3. When used as a standby instrument for the G3X, external navigators may not be interfaced to the Gi 275

4. The GI 275 as a standby flight display for the G3X must be connected to either a GPS antenna or a GTX 345 with internal GPS receiver

5. The GI 275 audio output must not be connected when used as a standby flight display for the G3X.

Can you clarify?

Thanks,

Skip

Definitely beyond my expertise and 1.5 hours of flight time on the new panel, but I'll keep the list as I figure these out, maybe with a little help from the avionics shop.

@Baker Avionics, can you tell us what the most current revision number is for the G3X Touch STC Installation Manual and also if any of the restrictions quoted above for a GI 275 when used as a G3X standby instrument have been lifted. Thanks.

Skip....#3:

The Garmin GI 275 display instrument, installed by STC SA02658SE, may be installed with a G3X PFD on certified aircraft to provide standby Attitude, Altimeter, and Airspeed Indicator functions (except in G3X installations which include Copilot displays).

Thanks, Greg. So, if I understand correctly, the GI 275 still does not integrate with the G3X and is merely a standby instrument in a G3X installation due to the limitations placed on the GI 275 by the STC. Is that correct?

Mulling the exact same question for my future planning, I would appreciate if you elaborated on this.

Regarding whether to go with the Garmin EIS or separate JPI:

I haven't been able to fly hardly at all since I got my plane and new panel back, so I have nothing to complain about with the Garmin EIS. On the one hand, so far, so good. The Garmin EIS on the G3X has the info I need and uses less panel real estate, has the Lean Assist that I'm adapting to after the JPI 700, and it has downloadable data (which I still have to learn). Also, the engine data is available right in front of me now instead of off to the side, but I could have gotten a JPI in the same neighborhood. 

On the other hand, JPI is an expert company in the EIS business, and I like their display. Plus, I could have re-used my existing probes, so maybe it would have cost a little less; hard to say. Also, I saw the comments about losing all my engine monitoring if the G3X display goes, but I also saw some mitigating comments on that score. On that last point, I guess I'm satisfied to make the leap of faith that the certified G3X will be suitably reliable.  

So like all this stuff, personal preference...... Probably not real illuminating. I'll have more of an opinion on the Garmin side of the equation in a month or two.

I had an EDM 700 and installed a G3X Touch with EIS. I reused the JPI EGT probes and JPI CHT probes for Cyl 1, 2, 4. Cyl 3 had the factory CHT probe and a 3/8" ring probe for the EDM, so I had to buy another JPI CHT bayonet probe for cyl 3. I kept the same Flowscan fuel flow transducer. So, the only other transducers I had to buy were for RPM, MAP, oil temp, oil pressure and fuel pressure.

Personally, I'm not worried about losing engine data if the GDU or GEA quit. I figure that is no more likely to happen than the JPI dying. And, with a NA engine, I can operate safely without any gauges anyway.

I really like having the MAP and RPM located close to the ADI.

I don’t like EIS on G3X just because it takes up space and prefer my PFD panel to be larger than smaller.
