Love my new engine monitoring system.

Dave S. from Missouri
Beechcraft Bonanza Model 35

[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

Very easy to install and directions were straight-forward.

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

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.

Logan from Montana
Cessna 172B

The OPT-1 is more readable than the factory Cessna oil pressure/temp gauges.

Daniel N. From California
Cessna 175 Skylark

The reviews online were very good. Customer service has been great.

Jason H. from Arizona
Cessna 172 Skyhawk

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.
