Help with EGT Probe and a Suggestion on Fire Extinguisher

[Ernie Martin]

For PatrolPilot: the key question is whether the Aircraft Spruce type K probe works with the ORIGINAL factory gauge? let us know when you find out.

I understand the concern about using EGT for leaning, since you are getting an average of all cylinders and one of them may be running too lean and cause damage. That's all I've got and I use it for that (running ~ 75 degrees ROP), but I also watch other parameters like cylinder head temperature.
