WB & logging

[Bruce]

Dunno if I mentioned it but I redid my MAT sensor mounting,  Took and opened
up the 3/8 pip thread to 1/2 and then used a nylon reducer to isolate the
sensor from manifold heat.  Net result no change that is enough to note.

Gotta get and EGT setup.
In tinkering with some on the fly timing changes got best mileage when MAT
temp was lowest, now to find out why the timing changes were reflect in the
MAT so drastically.  An why PWs changed so much.   While AE might take a min
to burn off, timing changes at cruise can take 10 mins (or more) for temps
to stabilize.
