RPM is always included on the CGR-30P, as is EGT and CHT. You choose the next five primary functions. In your case, Oil Temp, Oil Pressure, Fuel Flow, left fuel and right fuel. Carb temp and OAT can be displayed on the secondary page as optional non-primary functions ($94.00 each).

Very happy to read about your satisfaction with our instruments. I hope you get the issues resolved with your EDM900 and it offers you years of trouble free service! If it doesn't... :-D

We can certainly display oil temperature on the CGR-30P Premium as a primary function that will replace the factory gauge. We may be able to offer a trade-in rebate for that EDM700, as well. Do you have any pics of your plane in flight that you would like to share?

Hell all- I'm hoping some of you proud Mooney pilots can help with a request. We're looking for a few before/after panel pics of CGR-30P, CGR-30COMBO installations for upcoming marketing material. We could also use some great pics showing your Mooney in flight. If we choose to use your pic, we would be happy to offer a discount on a future purchase. Please PM me with any questions, or forward pics to support@buy-ei.com. Thank you!

To clear up any confusion, the Premium version of the CGR-30P always includes RPM, EGT and CHT. You have your choice of five additional primary functions (required instruments with limits/redlines) and five non-primary functions (OAT, carb temp, flight time, etc.) Additionally, we are currently offering a $1000.00 rebate on our CGR-30COMBO package which prices it very attractively.

$1495.00. That basically gets you a brand new display and one-year warranty. The retail price on a new display is $4550.00. If you've got a radial engine, we now have a digital depiction for those, as well. You'll have to forgive the COM errors as I did not have time to set up an emulation.

You're not going to want to hear about the new MVP upgrade we have planned... J/K! If I can help any further, please let me know.

It appears some of our friends are not aware of the new MVP-50 display. Roughly two years ago, it was updated to a much higher resolution, SVGA screen. It now appears very similar to our CGR-30P. I've attached a pic if you'd like to have a look.

I'd perform the three tests I described in my previous post and see what you get. If all three data points are within a couple of degrees of what is expected, it is entirely possible that the JPI was reporting incorrect temperatures. This is not an indictment of JPI's products, the same tests can be performed on their equipment. What type of probes were used with the EDM700? Cylinder well? Spark plug gasket? What type of probes are currently installed with your MVP-50? Different locations will impact temperatures.

I'm curious where you got your information from. Not criticizing, but I'd appreciate if your could provide the sources of the independent research as I'd like to read it. Regarding accuracy, you can take any of our probes and perform three very easy test that will result in three data points. For example, let's take a look at a CHT probe. Before starting the engine, verify that the CHT is reporting OAT, within a degree or two. This test works better if the aircraft is in a hangar, where the sun cannot influence temp. Second, remove the probe and submerge it in an ice bath (70% ice/30% water). CHT should read 32°F within a degree or two. Lastly, submerge the probe in boiling water. Depending on elevation, you should see a temperature very near 212°F. Probe "accuracy" can depend on many factors, location being the most important. A probe installed in the cylinder well will result in a different temperature from an upper or lower spark plug gasket probe. The upper will typically indicate cooler than the well probe due to engine baffling and the lower spark plug probe will typically indicate hotter due the proximity to the exhaust. Use of fire sleeving can assist with this. EGT probe temperatures are very much dependent on the location of the probe, type of thermocouple used, thickness of the probe, etc. That is why no manufacture specifies EGT limits. While absolute EGT should be considered in normal operation of the engine, temperature relative to peak are more important.

Happy to help!

Just for reference, our R-1 begins to accrue time at a ratio of 1:1 at 1300 RPM.

Great speaking with you today!

Hi Kris, Please send me a PM with your details and I will do my best to help you. I'd like to get a new EGT probe to you if you have one that is being problematic.

Saw this a couple years ago.

To answer a few questions, the CGR-30P does include red and yellow annunciator lights that will illuminate when any primary function violates a corresponding limit. If a change to the configuration needs to be made, the display will not have to be returned to do so. Most of the time, that can be accomplished via e-mail and the CGR's USB port. Additionally, the CGR is flush mounted and does not overlay the panel. As an added bonus, we've just launched a rebate! If interested, have a look at the link below. buy-ei.com/rebate-2018/

Sent you a PM.

Stay tuned...

If anybody has questions, I'm happy to answer them.

They sure are! If you would like to use the existing sensors, we can build an adapter harness for $100.00. Additionally, we can supply probes and harnesses for the UBG-16 so you would be able to sell the entire system on the second hand market and recoup a bit of the CGR-30's purchase price while saving on installation costs.

Hi James, let's see if I can answer all you questions. 1. Thermocouples require two reference points, cold and hot. The cold joint is a temperature compensation diode at the back of the instrument or at the EDC (CGR and MVP installations). The hot point is where the TC wires meet at the probe tip. We specifically designed un-grounded probes to increase reliably. We isolate the TC wire from the actual probe as the two different metals (alumel and chromel), as well as the actual probe and solder all expand and contract at different rates, eventually fatiguing the joint. That is typically why grounded probes fail at a much faster rate. The TC wire is actually soldered to the probe tip. 2. The CGR-30P always includes RPM, EGT and CHT (bar graph analyzer). You select 5 primary and 5 non-primary functions. Primary functions are those with limits/redlines that will replace existing instrumentation. Worth noting, if you elect to monitor fuel level, each tank occupies one primary position. 3. All of the probes and transducers connect to the EDC (engine data converter). The CGR-30P is wired to the EDC via two RS422 wires. For added safety, fuel and oil probes/transducers are installed on the engine side of the firewall and sensors such as vacuum and manifold pressure are installed on the cockpit side of the firewall. You can keep the Insight gauge, but you would need to install many redundant probes. For example, EGT and CHT. The Insight probe cannot supply signals to both their system and ours. If you were to remove the Insight instrument, our system can interface with the existing probes, saving you labor. 4. The CGR-30P easily interfaces with most panel mounted GPS units to provide MPG, distance to empty, fuel remaining at destination, time to empty, estimated total remaining, etc. 5.If you wanted to monitor amps, we can supply you with a 100amp shunt, or you can use your existing shunt. We would need to know how many amps are required for a 50mV drop across the shunt so the CGR-30P can be calibrated correctly. 6. If you wanted to monitor vacuum, we would include our PT-05DIFF transducer to do so. The transducer includes two hoses. One to be connected to the gyro pressure line and the other to overboard pressure. One final consideration, we are offering a 30P and 30C combo package with a very attractive introductory rebate. Up to $1000.00 off. Basically, we're adding the 30C for an additional $400.00, which is incredible as the 30C can replace up to 16 primary instruments. 8 are included in the purchase price. I hope this helps.

That's what I called it...many years ago. :-D I had only been in a 747 and 737 at that point.

Thank you for the kind welcome! I do work for E.I. in sales/support. However, I'm also a passionate GA enthusiast/pilot. My first flight in a "tiny" airplane was in a M20C.

Either the CGR-30P, CGR-30C or MVP-50P can interface with a multitude of different fuel level probes, including the factory resistive probes, our P-300M magnetic probes, CiES probes or even capacitive probes. Keep your eyes out for an attractive rebate on a CGR-30P & CGR-30C package.
