CHT Probe

I just bought one a few months ago and will check where I got it. I know that Don from Commodore told me that it is best to change the gauge and the probe so that they are calibrated. I didn't buy both, just the probe. My gauges have never matched and that is probably why. No worries though because the next flight I make I will be relying on the JPI EDM 760 that I am currently installing.

I will look and see where I purchased the probe from. Will it be the same as yours? Same engine, right?

Dear Sir,
IO-360A on the 336. The Cylinders are the same though. I agree with matching the probe to the gauge, BUT, it is a lot easier and cheaper to just calibrate the system as a whole once the probe is replaced. Not a bad idea anyway, who knows when or if it was last done.
Regards,
James

Dear Sirs,
thanks to all for your help. Problem solved. Good CHT readings again.
One day all the old gauges will come out and something new and shiny will go in their place.
Until then, what has been good for the last 47 years should continue to do the job.
Thanks again.
James
