<<For a carb induction system this would be beneficial to signal the
possibilities for carb ice, but in a turbo system what can this tell me?
Maybe show the temp difference between outside air and compressed cooled air
would signal a problem with the intercoolers. ????>>

I would say that the inlet air temperature is a valid piece of information
to have - how useful could be questioned.  A temperature too high would
invite detonation and higher temperatures reduce power output so it is
actually this temperature rather than ambient that should be used to
determine the "density altitude" of the engine.  Trouble is there is no real
data available to use in this calculation and I've not heard of a upper
temperature limit published by Continental.  Therefore you would have to
establish your own limits.  I plan to have this information available, but I
admit I'm not sure what I will do with it.
