Hi John,

Try running on the B controller.  The inlet air temp sensor doesn't
affect mixture on the B controller.

Flying will probably result in better air flow through the cowling, but
not guaranteed on an untested configuration.  Taxiing into a good stiff
breeze could give you some indication of whether the higher air speed
will give better cooling.
