Gary.
I know you are known to have noted temp differences between the brands. Can you clear something up for me.
If your cht is a theoretical 350 which would give the number closest to 350?
You say that jpi reads higher. Does that mean that the ei would show a number lower than 350, or that the jpi would read higher than 350?
Thanks for clearing this up for me.
Kevin

At around 350 degrees, both units read about the same.
I'm not sure what your objective is.
If you have an EI and you climb out at 400 degrees then as far as you're concerned, it's 400 degrees.
If you have a JPI and you climb out at 450 degrees then as far as you're concerned, it's 450 degrees.
Really, what difference does it make? If you just want to see lower temps, get an EI. If you like the features of a JPI, get a JPI.
If the EI had the features of a JPI and wiring like the JPI, D-sub connectors, thin wires, etc, I wouldn't have a preference.
The JPI uses grounded probes. In the absence of an ice bath, the EI uses the unit as a common reference. Do some homework on the internet and determine for yourself which ones are consistently more accurate.
I wish Aviation Consumer would do a study on them both.
