Gauge works great! Very happy with purchase.
Great service for Electronics International. Very helpful with what it needed for my aircraft. My mechanic has installed several of these units and highly recommended this for my aircraft.
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Works Great! Love it!
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.

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.
Great product, frees up space
Keep it up. I’ll keep coming back.
EI has the best customer service of any company that I’ve ever dealt with.
Love it!
Sales reps have been very friendly and helpful.
