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.

I have been flying with EI instruments for over 20 years. I purchased the CGR-30P to update my engine instruments into one modern package.
Nice bright display.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.

This is the second product purchased and I am completely satisfied.
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.
The layout and quality is impressive.
Very accurate readings! The “analog” style LED arc means at-a-glance tach readings that allow the pilot to keep his attention where it matters, not reading a gauge. The digital readout is great for maintenance checks and mag drop tests.
