[s-cars] IAT

[David Forgie]

Bob:  I would look to the G62 coolant temp sensor before the IAT since the default signal for the
 IAT is equivalent to 40 C, i.e. hot not cold.  The G62 defaults the other way, to a cold temp 
= ECU thinks it is cold out and enrichens the mixture.

Just another problem squirrel to chase up an UrS tree.

And we know how you West Virginny types like squirrel.
