Anyone have EI CGR engine instruments?
 

We are looking at replacing our engine instruments with the EI CGR TWIN PRIMARY PREMIUM package. We will do a field approval since it's not on the list. Wondering if anyone else has already done this? If so, any chance you have a picture of it installed and/or the Field approval? It would be greatly appreciated.

Thanks,

Tripp

I opted for the EI-MVP50P, if you want a pic that install, let me know.

If you have a photo easily available I’d love to see it.

Thanks.

Here ya go ...

Nice!

The upper one has an "unsafe" light and the lower has a hydraulic pump light.

How are those connected? I'd guess your unsafe light would be extinguished if you're on the ground.

The "HYD PUMP" light indicates when there is power being applied to the pump motor. If the amber gear up light or the green gear down light is illuminated and the hydraulic pump is energized, the gear doors are open (or in transit).

I still have a couple configuration issues to work out, this is one of them. Yes, the "UNSAFE" light should be extinguished when on the ground. The "UNSAFE" light will illuminate when either of the throttles are retarded with the gear not down, or when there is no power on either the gear up or the gear down panel indicator lights (or gear is in transit).

This is a picture of the System pages of the MVP displays. System pages for the MVP-50P

There are gear down and locked annunciators for nose gear and right gear. Since they are wired in series (nose, right, left) to get to the green down and locked light on the panel, I will be able to see downline as far as the circuit is completed.

Since you are looking at the CGR-30, here is a picture of a CGR-30 install in a friend's C-340.

Thanks for both pics. It's really helpful. Is there an STC for your instruments or did you have to do a field approval?

You're very welcome. The MVP-50P is STC'd with an AML listing for my plane.

What all gauges is this unit legally able to replace?

TACH
FF
Oil Pressure
Oil Temp
Fuel qty
CHTs
????

Rick,

Do you remember if you needed the 20ft cable for those? Also, what fuel sensors do you have with it?

Thanks,

Tripp

I’ve been considering the GI-275 as EIS option from Garmin.

Has anyone done the math on cost for all these to replace all primary functions?

GI275 x3
MVP-50 x2
CGR 30P x2 (x3?)
EDM 960


Anyone consider CIES fuel senders?

Mark,

The MVP-50P is a certified replacement for all engine, fuel, and electrical instrumentation.

It's not certified for removal of the pressurization instrumentation nor for landing gear position indications, although I've duplicated those original indications in the MVP-50P boxes.

Tripp,

I did not order extra length cables with the units. I think I recall asking them about that and their reply was that the cables I need come with the units.

I am using the original PennyCap fuel sensors ... I hope! We will be doing the fuel calibration in the next week or two. EI said they should work fine ...

Rick,

Do you recall what it cost to have the panel recut to fit the 50's?
We are really going back and forth over whether to use 50's or 30's and what the real total cost of each would be. Any pricing info you have would be really helpful. You could email me directly at TXSOCCERREF@GMAIL.COM

Thanks,

Tripp

Thanks to Rick Erwin for sharing his MVP-50 photo.

I'm planning the same installation in the April timeframe. I was investigating JPI EDM900, EMD960, and the CGR-30P. JPI doesn't allow two EDM900 for twins, and for me the EDM960 feels to clutter, plus I wanted to separate my engine monitors for each engine. I considered the CGR-30P, but for a few issues.
1. No STC (it would have to be done with a field approval, not a show stopper).
2. I kept adding up all the gauges I wanted to replace and ended up 1 or 2 short.
3. I didn't see a separation between my aux tanks and main tanks. It seems it was adding up both for a fuel remaining reading.
4. My most important reason was there was gauges on different pages and I didn't see a way to place it in a scan mode between the different pages. I.E. the fuel remaining is on a different page, it seemed I would have to manually toggle through the pages to see it. The MVP-50 has everything I can glace at without any page cycling.
