Anyone have EI CGR engine instruments?

[CO_Skymaster]

To Rick,

I'm getting closer to purchasing my MVP-50's. EI said they might have a rebate program in place around Sun-n-Fun in April, so I'm targeting that time. I would appreciate if you could answer 2 questions since you already bought one.

1. I noticed on your picture, you have an ALT1, ALT2, BATT, and BUS. My Skymaster has a switch that changes from REG1, REG2, and BATT. I guess that is for the pilot to switch since there is originally only one Volt meter. Did you remove that switch and this is how your system looks at the voltage pickups.

2. Did you use the EI P-300M fuel sensors. My mechanic recommend a fuel sensor, but it's twice as much as the EI sensors. I just wanted to know if you bought those, if you are satisfied with the sensor.

Thanks for any help,

Karl

Hi Karl,

1. I did not have that switch, and I had a single voltmeter that read bus voltage. I wanted to be able to see the various voltages to know what’s going on with the electrical system, so that’s how I designed the layout and configuration.

2. I used the EI fuel sensors recommended for my installation. I have yet to fly the plane, but my IA has run the engines and said everything was working fine.

I hope this helps.

Rick

Yes, it does.

Thanks

Just FYI - - I've got some FAA airworthiness guys working with DER/DAR at EI to get the EI CGR-30P approved for skymasters. Eventually, EI wants the 337 on the AML for the CGR-30P combo STC. No word yet on completion dates for the project, but EI is working on it.

** July 2021 Edit: My FAA airworthiness guys are telling me that their position is "Non-STC'd engine instrumentation is not eligible for Field Approval, any any request would have to be forwarded to the Airworthiness Certification Office for Evaluation", per their job aid . Specifically, Row D.13k or D.13t requires either a STC or an EVL (at the ACO). Bottom line for me: Until EI gets the CGR-30 added to the AML, it's a no-go. I'm now really thinking JPI-960.

My cluster gauge is on its way out the door (bad CHT gauges and senders with no replacement available, cracked glass, etc) so I am going to do the cluster replacement with my 73G model first. I talked to Blake from EI and he confirmed that I could do that and install two EDC units, one for each engine, then install the other instruments later. Still needs a field approval, so when I get some clarity on that I'll post back.

Who were you speaking with at EI? I have cash in hand if they come up with and STC for the CGR-30P Combo. I've looked into doing a field approval, but it'll add at least $3000 to the cost of the system which would cause me to go a different direction. I would much rather have the CGR30 system.

I last spoke with EI in early April 2021 when they advertised a sale for Sun-N-Fun. The process for an individual field approval engineering and adding the aircraft to the AML is nearly identical on their end, so they're opting to get the CGR-30P & CGR-30C approved for the 336/337 and added to the STC AML. I was assured it was "upcoming" on their list, and we'd see them complete their work "soon"--then a bit longer for FAA approval. I came away from the conversation with the impression it'll be a reality this calendar year, and maybe as early as summertime. I am ready to order the day they tell me we got on the AML. So, I remain optimistic.

Have you decided on the configuration you're looking for (functions, etc.)? The order form is pretty detailed and offers lots of interesting options!

I'll send them a note expressing my hope that they are working to add the Skymaster to the AML, in the hopes that it continues the momentum that seems to be there. I did look through the options, but there are SO MANY that I'm really going to dedicate time to work through all of it. I'd love to hear how you plan to set things up.
