G3X Touch EIS

[PT20J]

Looking for a pirep from anyone who installed the Garmin engine monitor (EIS) option with a G3X. I never liked the EIS in the G1000 (too many button presses and EGTs had very slow response time) but perhaps Garmin has improved it.

I'm a fan of mine. I like that the EGT graph is visible from the side, and that even when its in the small mode, it shows the temp of the hottest EGT and CHT, and a Little graph of all the cylinders. It works pretty well, and didn't really take any time to figure out how to use it. I removed the JPI simply because lack of space, and I wanted a clean and simple panel. I'd definetely do it again.

I'll add that theres no button pushing. Simply touch the compressed engine monitor, and it opens the full EIS on the second half of the screen. You have the option to use buttons, but its easier to just tap the screen and have everything open.

@donkaye, I’d value your thoughts on the Garmin EIS vs a JPI 900.

We came within inches from installing a 7 inch txi engine EIS but we couldn’t make it fit. I’ll probably regret that decision for the next 20 years...

I can't offer much assistance here in that I have never flown a plane with the Garmin EIS except for the G1000 and that is different from what you are asking. To me one big negative of the EIS is that it takes up screen real estate unless you buy the  separate 7'' display.  JPI makes good products, but a student I have has the JPI 900 and the numbers are so small in the column beside the engine graphics that I need a magnifying glass to read them comfortably.  I'd personally never buy it.  I do like a dedicated engine monitor, and I have really been satisfied with the MVP-50.  The EIS does have the ability to send data the iPad in real time so you cans how your engine is running without downloading the data when you get home.  However, if it were available when I did my upgrade, I think I would still choose the MVP-50 because of all the things it can do.  In particular it has two registers for fuel used, one for fuel used since adding fuel and one for fuel used for each trip that resets automatically on engine shutdown.  If I'm taking my plane to a student to do instruction it is easy for me to determine how much fuel I used for the trip without any computations.  There are other things I like about it like simultaneous readouts of temperature in both °F and °C.

I can read my EDM 900 just fine

I’m not sure what you’re asking for?  Pictures of the 7 inch unit we didn’t install?  Pictures of my wife not happy with the amount of time I’ve wasted with the shop working on it?  Or pictures of the panel?  Well I don’t have recent pictures but here are a couple old ones...top one shows the pfd (not seated, just resting on top) and the lack of space to the right for the 7 inch mfd.

I have a jpi930.  I like it.  However, if i were to start from scratch and build my own panel, I would have Garmin all the way across-pfd, mfd, eis, radios, gps, transponder.  The interface is solid, all are about the same logic and they work together perfectly.  My jpi is good, but just doesn’t integrate as seamlessly with the other avionics.

downloading to GP is a great development too.

Has anyone uploaded engine data from a Big G engine monitoring device to Savvy.com?

Simple yes / no will be fine...

 

Does the big G engine monitor not give off all the false momentary warnings that come with rpm over-run during T/O run?

Best regards,

One advantage of the garmin system is the avionics shop sets the limits. They could for instance put the 2700 rpm that the prop is designed to run as a normal not already in the red.  Or give some room on the fuel flow...

I really like mine, and to follow up on the comment above, even I can easily go into setup mode and change the limits (I could make my CHT redline at 425 for example).  Sorry for the low quality pic but this is a still shot from a video I took yesterday.  I opted for the 7” MFD on the right and usually use it for the EIS.  Adding the screen was cheaper than a 930 and you can use it for other things too.

The 7 inch g3x is the perfect add on mfd, even for a pair of G5’s or an aspen. You get EIS capability, touch screen interface, maps, charts, remote com control, cheap adsb in (gdl 50r), etc for the same price as an aspen mfd display or a jpi 930.

I finally found the data logging description. It’s a typical Garmin manual: everything is in there — somewhere. Just not where you might logically expect to look for it, and the index is as useful as the MS search. 

I flew a C-172 with a G3X today and played with the EIS. It worked much better than the G-1000 TR-182 I flew years ago that had terrible lag and hysteresis. I also like the presentation. It only has one Lean Assist mode — so no LOP lean find like my EDM 700. But my GAMI spread is only about .3 with stock injectors and so I don’t really need it anyway. The spread was so bad on the C-172 that I never could get #2 to peak before #4 was so lean that it ran rough. 

I’m definitely leaning toward the Garmin over the JPI. @carusoam Anthony’s comment about old technology got me thinking: Why put an old design in a new panel?

Skip

Edit: Clarification: My focus was on leaning using the EIS. My comments about G-1000 lag and hysteresis were in this regard. 

Edit 2: I re-read the manual and now realize that since the EIS indicates both the first and last cylinder to peak along with the delta EGT for each from it's peak that it provides the same information that the EDM 700 lean find mode does, just in a different manner. I just didn't observe this because the #2 cylinder didn't peak before the engine got rough. It should work fine on my engine.

How is the fuel totalizer displayed - is it just a fuel flow? Is the endurance shown based on fuel sender minus FF, or is that a separate totalizer? If the latter, is there an alerting for mismatches? 

I couldn't find that information in the G3X pilot guide.

Fuel flow, fuel totalizer, and fuel tank gauges are all shown with endurance, range, and mpg.

Thanks - I missed the information in the warning section.
