First-generation G3X compatibility with Continental CD-300 engine

Hi everyone,

I have a question regarding the compatibility of my first-generation Garmin G3X avionics with the Continental CD-300 engine.

Is it possible to use the first-generation G3X with this engine? Has anyone successfully integrated this combination, or are there any known limitations or required interface modules?

Any advice or experience would be greatly appreciated.

Thank you very much for your time and assistance
