CGR-30P Basic Package Configuration Worksheet * CGR-30P Premium Package Configuration Worksheet * Easily replace several of your aircraft's primary and non-primary engine instruments
with one EI CGR. For example, simply replace your existing tach with a CGR. In
addition to replacing our tachometer, the STC'd CGR will replace MANY of your
existing primary and non-primary instruments in the same instrument, in the one
3-1/8h hole. The CGR mounts flush with your panel and doesn't protrude from your
panel (as competitor's gauges do). The CGR-30P comes standard with a state-of-the-art, full color bar graph which assists with ROP/LOP leaning. Additionally, the bar graph has both normalized and digital readout screens. No other bar graph in the industry comes close to providing the number of options the CGR-30P offers. In addition to its bar graph, the CGR-30P can be configured to display a combination of the functions listed below.
Available Screens: In addition to the Main Screen, the CGR-30P offers a Secondary Screen, a Fuel Quantity Screen, and a GPS Data Screen. These additional screens give the CGR-30P flexibility not found in any other engine instrument.

Reviews
Ive had the CGR-30P on my Cherokee Six for several years now. It works great and it is one of my most referenced instruments in the cockpit. The CHT monitor was critical in diagnosing an in-flight emergency on cylinder no. 4. It is also particularly useful and very accurate for monitoring fuel consumption in my four tank aircraft.
I purchased the 4 cylinder, Premium package. It took 10 weeks from ordering and my credit card being charged, to EI shipping the unit. They shipped it in a single-wall box, with the head unit hard up against the corner of the box, with no foam shock protection like typically electronic instruments should have. I am worried about the long-term reliability of the unit. Upon complaining to EI, they claimed this was their standard pachaging method, and had yet to cause any issues. I was offered a return or a $180 extended warranty.

The CGR30P-6-P allows for 6 primary engine functions and the 6 you select will come with the required probes.
While the CGR-30 Primary Engine Monitor can technically be programmed to have a custom lower alarm limit for CHT, EI is bound to go by the limits set forth in the POH of your aircraft. The user cannot themselves, program this.
Per EI, the CGR-30 can be configured to work with may portable GPS's such as the Aera 500. Please state which model you have when you at the time of order to ensure the correct cable is included.
Per EI, the CGR-30 cannot show fuel pressure as a primary on the main screen.
CGR-30P records engine information from 1 to 3 times per second. You can insert a USB stick and download all of your engine information and view it on your computer with a spreadsheet program such as excel.
As the CGR-30 is a primary replacement instrument. You would not need to keep your original fuel gauges.
