Great Product, that provides a lot of very helpful engine data in an easy to use and see display! We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive. The CGR-30 had quite a few positive reviews online from other users.

Your customer support is far superior . . . . I appreciate all your help.
This is a high quality instrument and works perfectly. Well designed, well constructed and well documented. I couldn’t be more pleased!
EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], 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.
