I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
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.
