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.

Easy install and great gauges. Previous experience showed that EI’s units were… great prices and even better instruments. Being able to install the gauge as a primary instrument was a major plus.

Well documented installation process and Support was helpful.
[The EAC-1] looks great running… The wiring harness was very well fabricated. Installation was easy- fit perfectly in an existing hole in panel. The brightness of the display is excellent.
Big improvement over old cluster (gauges). Good customer service.
