Insight G4 vs JPI 790 - pros and cons?

[n86121]

Okay, okay already.
I am considering an engine analyzer.
It amazes me there are no decent videos showing these in use,
Neither company's fault, just terrible movie makers.

Everyone raves about having an engine analyzer.
AND ...I guess it would ba a 'capital improvement' too.

Will it improve my sex life?
Lower my mortgage rates?
Extend my auto warranty?

Easiest to install while the airplane is filleted open for annual

KEEP SHADIN FF ???

My thought to keep my shadin FF display, for its nice big dedicated FF indicator.
To keep arithmetic simple for me, I match fuel flows F and R.
Big display makes that easy.


OPTION 1 - Insight G4
Install where EGT is now.
Shadin REMAINS at bottom of engine gauges.

OPTION 2 - Insight G4
Bottom of engine gauges, where shadin is now.
REMOVE shadin and EGT.

OPTION 3 - JPI 790
Right over throttles, bottom of avionics stack.
I understand it can be set to scroll automatically between values?
while displaying bar graphs

One COULD remove shadin and EGT.
But again, shadin has nice big juicy display and easy to watch/track

---
All of these analyzers present a lot of data in small areas.
Their alphanumeric (digital) values may 10 point font?

Thoughts ....gents?

David,
My vote for “simplest” install: Option 4: insight G4 in custom panel at bottom of avionics stack and leave everything else alone.

There are many more options also: MVP50 for each engine, GI275 for each engine, and the EDM960. I went the dual GI275 route and really like them.

Same EIS question. I currently have 2- EDM 701’s and a Shadin. Need to come up three decades in tech and I want more accurate fuel sensors while I’m at it. The G-4 twin setup (packaged for a 337) is a fair bit lower priced than the alternatives and go into an existing panel cut out. I want it on the left panel for line of sight. I’m sure the 960’s are nicer but I don’t want another big square box cut out on my right panel. The G-4 can just go into one of the two remaining 3 1/8 holes on the left panel. I have to keep my T&B for the S-Tec unless I can get away with adding a GAD 43e. Not sure that would be a full replacement for the T&B for roll inputs? If so, all vacuum and analog gauges would be gone. How are you getting space in your center stack? For me, anything in the av center stack is not an optionas it’s too full already. A pair of GI 275’s would be great but cost is quite a bit higher than one G-4 which has a package already setup for the 337’s. I’d like to know what you decide to do. Please share a picture of your final setup. Mine is sitting in the shop pending a second fuel pump rebuild.

I replaced my old Gemini 1200 with a G4 and am very happy with it. I was able to keep the harnesses for the EGT/CHT, but had to add new wires for fuel flow, vibration, oil temp, oil pressure, OAT, etc.

It was well worth it. The old Gemini 1200 was a bear to download data from.

My only negative is the G4 doesn't have the "level the EGT" bars the old 1200 did. I kind of liked that feature as it was easier to tell which cylinders had an increase in EGT during a flight.

Did you swap out your senders for digital units or stay with the factory originals?

If you’re asking me, I put in CiES senders to feed the GI-275 EIS.
