Opinions wanted! CGR-30 P & C versus EDM 900

[oregon87]

All of the sensors/transducers are installed on the engine side of the firewall and plumbed to the engine.  Only the wires from those sensors penetrate the firewall and connect to the CGR's EDC (engine data converter).

Since the EI CGR-30's interface box must be mounted on the INSIDE of the firewall, doesn't this mean that fuel lines, oil lines, etc must still penetrate the firewall?

Why don't I see them in the photo above?  Thanks

Look who stopped in to answer your question!

 

See the EI response above…

Go EI!

Go MS!

Best regards,

@oregon87 @carusoam and others:  Can the EI CGR-30P/C display TIME TO WAYPOINT?  I know it says it can display time & distance to "destination" and to empty, but what if I am using a flight plan on my nav system and am wondering about fuel to my 2nd and 3rd leg?

Also, can anyone confirm the CGR-30's will accept GPS data format from an old GNC 300XL?  E.I. Sales didn't seem to have any documentation listing accepted input GPS formats.  Here's the formats our old nav system outputs:

ARINC 429; RS232 – Plotting (NMEA 0183 v.2.0), Aviation, PC Interface, Altitude Serializer, Fuel Sensor, Fuel/Air Data Computer; Gray Code, RMI Serial Data

Thanks much

One of the first things I did with my aircraft was to install a JPI 930. I can’t speak to differences between the EI and JPI instruments, EI was just coming on line when I did my work and JPI had readouts that I needed for my 231 that the relatively new EI did not. I have heard nothing but good things about EI. What I can speak to is location. We moved the 930 to the right side of the pilot’s panel, in the pilot’s normal scan and not way over on the co-pilot side. This has save my bacon more than once, any abnormalities become immediately apparent so I can do something about them rather than have a real problem develop. As to the 275’s, I have the dual reversionary 275s -ADI and HSI. They are very nice instruments. But for an EIS I would greatly prefer the larger display like the 930 and the much better definitionx. I had a JPI 700 before the 930 (old round gauge that fit a 3” hole), the def of the 930 is way way better. There gets to be quite a bit of information packed into a small space in the 275.

Either way, getting a primary engine monitor model that replaces the legacy engine/fuel indicators frees up a lot of panel space...  An essential improvement in my opinion.

I personally really dislike the two separate data files you get with the EI C & P combination. Without all the data in one file, analysis is a challenge. I do have one client that is able to combine them in Excel which makes a world of difference. But that takes time and do that on every flight file?

I’m prefer the EDM900. Upgraded my old 900 to the brighter screen. Easy data downloads  Here’s my setup
