Anyone have EI CGR engine instruments?

We can send all then details we went with going back and fourth with EI if that’s helpful!

For Rick do have pics of how the install went in 337K?

Any learning curves on the install / post install?

Thanks

I have some pictures... I’ll try to get an album put together in the next few days and place a link here ...

Thanks Rick
My skymaster is a 75 g model non pressurized non Turbocharged and is fixed gear so will not need any gear or pressurized inputs. I ask Ei if the heads would accompany those things in the event something happens to my plane if it would transfer to another one and these said yes it could be added to another plane later with those specifications

That's good to know. All the limitations expressed in the EI instrument would HAVE to be exactly the same for a different airplane, otherwise you'd have to send them your configuration files and they would have to update them for you. I don't think that would be a big deal though.

We have both engines off and I’m assuming you pulled all the old wires out, I am going to do a new weight and balance on mine, we will rent some scales and get a new weight on 504. How did you determine the weight difference after your install?

Yes, we pulled all the old wires out.

My IA has the scales and ramps to do the re-weigh, once we are at the point we can put the interior back in.

One thing to think ahead about is ... if you are going have new electronic engine instrumentation that includes a fuel quantity indication is: You will need to calibrate the new fuel indication system with the tanks incrementally from empty through full, but the airplane will need to be weighed while empty. So, try to weight it before you do the fuel calibration, otherwise you'll have up to 30 5-gallon buckets of fuel sitting around.

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.
