I have worked with and installed a few of your competitors’ and your systems. EI instruments’ ease of use and installation make these systems my go-to choice and number one recommendation to customers.

[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.

Dom M. from Australia
Van’s Aircraft RV-6

Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.

Robert B. from California
2002 Diamond DA40-180

Very easy to install and directions were straight-forward.

Paul H. from Oklahoma
Piper PA-28-151 Cherokee Warrior

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.
