I agree the temperature a cylinder can tolerate probably doesn't depend on the
airframe, but the method of measurement might. Where is the CHT probe on the

another.

In a sense, you're probably right. There's a threaded hole in the cylinder head. The
probe goes there, no matter what the airframe. The only way the airframe could make a
difference is if a) they have the probe in only one cylinder and b) the
temperatures on the other cylinders are known to be significantly different.

So, if Piper puts the probe in cylinder #1 for one aircraft and cylinder #4 in
another, the allowable max temperatures are likely to be different for the two.
