My mechanic said that your product was very good, and he was correct.
The tach looks and operates amazing. Extremely accurate.
I have heard only great words about EI… Won’t be able to install till at least April but I know you are very helpful when it comes to questions.

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.
