Love my new engine monitoring system.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.
Very happy with our new tachometer!
I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Great product. So easy to read compared to the originals.
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Looks Great, and intuitive to use. Packs a lot of information in a tight area, yet, I don’t need my glasses to read it!
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!
The tach looks and operates amazing. Extremely accurate.
