While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!

Love the look and having every piece of info in front of me… Better price and look [versus competition].
Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.

Great Product, that provides a lot of very helpful engine data in an easy to use and see display! We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive. The CGR-30 had quite a few positive reviews online from other users.
