Product Overview

TR-1 Features

Our TR-1 provides exceptional performance, reliability and features. If you need to replace or overhaul an old failing instrument, consider buying one of our TR-1s from a company which has been designing quality aircraft instrumentation for over 40 years. Purchasing our TR-1 is substantially less expensive than overhauling or replacing your old needle gauge.  We’re able to make this offer with a money-back guarantee because we’re confident you’ll love the performance, reliability and features these instruments offer.

  • Standard two-inch round (MS28042-1A mount), 4.23″ long.
  • Rugged and reliable design (unlike many old needle gauges).
  • Optional RS-232 input and output port to interface with EEC’s, FADEC’s and other devices.

  • Optional two open-collector (pull-down) for controlling external warning lights or props (0.1 Amps max).
  • Optional ARINC 429 compatible via the BC-5 (contact EI Support for details).

Customer Testimonials

My mechanic said that your product was very good, and he was correct.

Zarick J. from Florida
Mooney M20J 201

Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Phillip B. from Oklahoma
Cessna 210N Centurion / Turbo Centurion

Haven’t used it yet, but we are excited to & Love the way it looks!!

Larry A . From Idaho
Piper PA-28R-200 Arrow

Safety and simplicity!

Andrew L. from Florida
Piper PA-28-235 Cherokee Pathfinder

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!

Jeffrey S. From Missouri
Cessna 170N

I like how the kits ship with everything needed for install and the wire labeling was very helpful.

Nathan V. from Alaska

Good to go! Excellent instructions and easy install. Outstanding instrument!

Mark L. from Washington
Cessna 170B

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 nice product, giving a real advantage on fuel management.

Stéphane T. from France

Good equipment at a good price. I have used your products before and have had great success.

The [unit] is easy to read and quick to respond. I have multiple EI units and have had good experiences with all.
