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 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!

Always very friendly and knowledgeable staff. Over time, I have purchased six different EI instruments for the two planes I own. The instruments are easy to install, very accurate, and dependable. EI has very stable and easy-to-operate instruments.
[I chose the CGR-30P because of its] ease of use.

I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.
