I have not read this before so if I have missed it forgive me for bringing it up again.
As you may or may not be aware the pipe temp sensor will lean the fuel down on a cold pipe to bring the pipe temp up.
With a cold pipe the pipe temp sensor is leaning it down in an effort to put some heat in that pipe. I notice a .5 to 1 afr leaner when this is happening.
Will one point leaner afr push an already too lean area over the edge, maybe.
On a cold windy day it takes a while to heat that pipe with lighter throttle positions. Not very long when you hammer on it!
Remember a cold pipe can occur with a hot engine.
So for those of you that like to do every thing possible to prevent piston damage here is another thing to think about. Like you needed it!
