Straightforward installation instructions, great wiring harness. Quick answers from Tech Support.
Works great!
My interactions with EI were all very positive. When I ordered the Dual CGR 30 instruments I was told there would be about a 6 week delivery time. It took a little less than 4 weeks. I am extremely happy with the service and product.
Your customer service is excellent and your products are top quality!
E.I. Always Exceeds Expectations!

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.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
[I chose EI because they offer a] certified replacement vs. back-up only and they look great.
