Anybody go All In on a GI 275 EIS?

[Echo]

I am wondering what the experience was in installing a GI 275 was like?  If I went this route I would need to purchase additional sensors to get MP, RPM, Fuel, oil pressure as well as fuel indication.  I want to replace ALL the analog OEM gauges in a '65 M20E so need primary.  Thanks.  Willing to listen to suggestions on why a JPI or EI or other would be wiser.  Thanks for input.

Ive had all three. Currently have the GI 275. I went all in as you say. some say its too small, i dont find it to be and im 62. the best feature is that it can display on the ipad and automatically records data to flygarmin. it had some bugs at the beginning, but works well now. IMHO its better than the JPI or EI, but it is more expensive installed.

Was fuel quantity difficult?  Just use OEM resistive?  What were bugs?

Who did you buy from Mike?  Regrets on any functions?

The Garmin EIS has become incredibly popular as they have developed a large market share. It doesn't really matter which Garmin display is used, GI-275, G3X or G500, they are all almost identical in their capabilities and their software continues to improve. But the GI-275 is the smallest screen and perhaps the most challenging to get everything you want on a single screen display. The other nice thing with the Garmin route is you get greater integration of the engine data with flight data if you are either a Garmin Pilot user or down the road install a G3X. If you went the G3X route, you would just move the EIS functionality to the G3X and probably swap the Gi-275 EIS with a GI-275 adhrs. But lots of possibilities.

But I'll add I personally prefer the EDM-900 over the Garmin EIS despite having a G500 and GI-275 backup adhrs driving my GFC-500. I prefer how everything is on one dedicated screen on the EDM-900 that is quite readable - without cycling through screens or menus. 

It doesn't matter which route you go, any primary monitor will require adding all the sensors you presently don't have. So it really comes down to your own personal preferences and how you intend to fit it into your panel.

Really appreciate that detailed reply.

we did. we like it. if you get an MFD you can diplsay the EGT page also.

Wow, that panel looks great Byron.  Did you also to CIES for fuel level?

Is this racing phot?  Getting after it down low  

[cdikd]

Really happy with it ! It's not too small.

He’s at the end of descent to get under the shelf, and it’s in mph.

[jetdriven]

It is miles per hour, but that was the level flight before the descent to the airport.  I wasn't particularly racing it, but I was letting it eat.

I notice that you don’t have % power.  I just had mine installed and I don’t think I have it either.  Do you know why?

 

[zehutiman]

Regarding size, I was skeptical at first, too.  But, you sit so darn close to the panel that my 61 year old eyes have no problem with it.

You need the 500$ GTP59.

I too had the 275 eis installed when I did some avionics upgrades:

 

It works amazingly well. Love the additional data the eis brings. A couple of issues that you may run in to. The sensors are so sensitive, and if there were "snubbers" built in to the old lines, or the old gauges just had dampening built in to them, we lost that at install. So MAP, OIL, and what appears to be fuel pressure(just got my snubber in to fix the spiking with it to see if that is fixed) fluctuate all over. I couldn't tell what my MAP was at all. Buying Omega snubbers PS-8G and PS-8E resolved the issues.

You have to buy the 500 garmin temp probe to get the %power, but utilize that pretty much all the time. For me, it seems to align pretty well with the poh. 
You'll need to get new fuel senders (definitely suggest CiES sensors). Also, I had a problem getting the fuel pressure sensor. There is a sensor kit you buy with the instrument, and it doesn't come with the fuel pressure sensor. Call Garmin for it. Nobody seemed to have either sensor in stock. Garmin didn't have their garmin brass part, but had the GPT Stainless Steel one in stock. 

Calibrating the fuel senders was a bit pita too.

 

That's about all I can recall from installing it. Good luck with yours!

 

Sincerely,

Chris

Really nice looking panel Chris.  I "cheaped out" and ordered the non-primary EDM830.  I can retain OEM gauges.  No big deal.  Half the price and I get % power

 Nice. One of my fuel gauges had been messing up, and so I was really looking at getting rid of them. But 179 kt GS!?!? and 72.3 Gal remaining!!

That is my last plane (Missile) with EDM830. That plane was fast up at altitude.
