The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
RPM Isolator Package
The RPM Isolator Packet contains the essential components required to condition the RPM signal from your Magneto for accurate readings on Electronics International instruments. These isolators are designed to attenuate strong signals that can otherwise cause high or jumpy RPM readings. The kit includes primary ring terminal isolators for the mag switch, along with additional inline isolators to fine-tune the signal strength for various magneto types. This packet is compatible with the R-1, CGR-30P, CGR-30C, MVP-50P, and any system utilizing the EDC-33P.

Always a pleasure to do business with EI. Products ship rapidly. I have been using your products for 20+ years.
I started with a CGR-30C. I loved it so much, I added a CGR-30P… [Your customer service] was a great help configuring it and EI gave me a great deal. I am now an EI customer for life!

The display is large and clear. The functions are simple and easy to use. Great purchase decision.
Much better quality with the bezel and buttons and knobs [vs. competition]. Also much easier to navigate and add fuel.
