I like how the kits ship with everything needed for install and the wire labeling was very helpful.

The EDC-33 (Engine Data Converter) is sometimes referred to as a Data Acquisition Unit (DAU) and has a broad range of applications. Its main purpose is to monitor the probes, transducers and sensors mounted on the engine and airframe. It then processes this data and outputs it on a serial bus. This allows a Display Unit or MFD to display the data without having to perform the intense processing required in a set timeframe.Also, annunciators and status switches can be monitored.
The EDC-33 Engine Data Converter can be used on piston, turboprop or jet aircraft as well as helicopters. If an EEC or FADC system needs to be monitored, check out our BC-5 (Bus Converter).

We have other EI products currently and have always been satisfied.
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
Excellent Service, superb product.
All looks very nice. [I chose E.I. because of] previous experience.
Pleasure supporting folks with like values.
Installed digital volt/amp gauge in PA 28-181. Great unit easy to install. Much better than original.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!
Compact, precise, awesome!
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
Easy to install, and the CGR was set up to my aircraft’s exact specifications.
Great product. So easy to read compared to the originals.
