Hi,

Actually, knowing the absolute value of the EGT is not that important. It is quite sufficient to be able to determine your operating EGT with respect to peak EGT, without actually knowing the exact EGT value. So, within reason, it really doesn't matter too much where your probe is located.

I'm curious where you intend to run your engine based on the EGT values you measure?? Are you planning to run at peak EGT, ROP (rich of peak) or LOP (lean of peak), and by how many degrees if not at peak??

This is a very timely topic for me because I just took an engine management course (full scale) with Advanced Pilot Seminars in Ada, Oklahoma [link]http://www.advancedpilot.com[/link] that deals with all these issues. Even though we are talking about model engines, the operating principles are the same!

Thanks,

John
