Safety and simplicity!
Great to have all 6 egt’s, installation was straightforward. [I chose E.I. because of] price and availability.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Really impressed thus far . . . . a rock solid replacement for old mechanical gauges.
Awesome product. Fast easy installation.
My mechanic said that your product was very good, and he was correct.
Big improvement over old cluster (gauges). Good customer service.
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
EI’s team is great; you guys are the best.
Great customer service!
The CGR-30P is a fantastic product and EI has excellent customer service. EI is the leader in engine monitors with a strong track record.
I love my new EGT. Very accurate and has ambient air temperature so I know how cold my engine is before I start it. Easy to see lighting.
