Downside - A ton of wires from engines, but sufficient to do the trick.

The other option

Suite of EI CGR units to replace EVERYTHING
Two CGR 30P, one for each engine, replace MP and RPM
and a CGR30C where Shadin is, to replace everything else

The appeal to EI is a hub in each engine and minimal wiring from there to gauges.

Going through an extensive annual 'wallet-ectomy' this year,
and replacing the last window (front)
because it's not as nice as all the other ones which are new 'solar grade'

Other than grossly exacerbating the "wallet-ectomy", is there another reason a pair of Garmin GI-275 EIS gauges didn't make your best options list to replace everything? They're at the top of my list, but now I'm worried I'm not smart or thoughtful enough.

Good catch! I handn't thought of those.
Looks like $8k for the two displays, plus install.

One for each engine.
Even handles 4 tanks.

Hmmm.
Interesting.....

I see an STC to install,
but do they officially replace need for existing fuel gauges?

I think a pair of GI-275 EIS's would replace everything engine-related, including the fuel levels on at least four tanks, and be STC'd as primary-- even on our Skymasters according to the AML.

My family has 275s installed on one 337E and I'm doing another install now on my 337G.

They are excellent instruments but assume 10-13k all in after sensors and wiring. If you have capacitive fuel senders you'll need to change them to CIES as the cap versions aren't supported by the 275.

Cheers.

Good point on the CiES senders-- we did that during the last annual and it added ~13k combined for parts, markup & labor. Granted, a very significant chunk of that was removing and re-installing the Flint tip tanks as that's the only way to access the senders in those. YMMV. The CiES also require a dedicated ground wire, as I recall-- no big deal but maybe a bit more pricey since it is pressurized.

This one seems to have everything, PLUS vibration analysis. Appealing to a nerd.
Skymaster kit around $6k + install.

Any experiences comments?

Not primary, which I guess the 275's would be....?

I have an older Insight model, the 1200, and have liked it. My complaints are related to its age--the technology to download the data is via some HP Palmtop.

Insight has fixed this with the newer models, plus you get fuel flow and vibration analysis.

In my 20 years with the 1200 I have had to replace one temp probe. Thats it.
