[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.

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

Outstanding Customer Service!!
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Nice bright display.

Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.

A clear capable replacement for a cluster gauge. Vivid colors used which make it easy to see engine status at a glance.
