I’d like to get something worthwhile, but without breaking the bank or having the plane at the avionics shop for a month. Is there a reasonable gauge with good CHT & EGT readouts or is it best to spend the $$$ and get two EDM 830’s.

Thanks,

Tripp I have the Insight G4 and it provides a tremendous amount of information in a small package for a reasonable price. So far I've had to replace one EGT probe and that's it. One of the nice things about Insight is that they ship with Skymaster specific harnesses. https://www.aircraftspruce.com/pages...sight-twin.php

Having said, if I had to do it again I would go for the JPI EDM960: https://www.aircraftspruce.com/catal.../jpiedm960.php

In addition to that, I would go with the CIES fuel senders: https://ciescorp.net/applications/sm...rcraft/cessna/

If you do JPI + CIES...it means that EVERY SINGLE old gauge goes right in the garbage can and you have accurate, digital monitoring of every engine parameter and the fuel quantity.

Yeah, it's a lot of money but I've spent lots of $$$ in labor this year chasing old wiring.
