Ladies & Gents, This is not biplane related but this is the most knowledgable, helpful group on the internet and I hope one or more of you will share your thoughts.
I recently purchased a 1967 182 that is well equiped except it has no engine monitor. I've narrowed my thoughts to JPI or EI. Having just watched a friend search endlessly for some replacement engine gauges for his older Cessna (certified airplane remember - almost have to use Cessna guages) , I'm going to go with an engine monitor that can act as primamry for the inevitable time one of the currenntly working instruments fail. The pluses and minuses of the JPI and EI are (I think - open to be educated):
1. JPI is a little less expensive and easier to read without glasses.
2. JPI more expensive to install becasue of wiring under instrument panel (see more about this below).
3. The EI routes all the firewall forward wires to an "interface" box on the firewall and then just 2 wires from the box to the instrument. If everything is hooked-up, there can be as many as 90 wires on the JPI.
4. If one of the two wires on the EI break, I loose everything. Granted, I won't fall out of the sky if I loose everything.
So, does anyone have any experience with the JPI or EI? Am I overthinking this?
