Air temp sender location

The Cosworth carbon air box is supplied with a combined MAP and air temp sender, which measures temp and pressure inside the air box. After studying an ECU log file it reveals its location for air temperature is far for optimal. 

Blue line is air temp. The real temperature this
evening was around 11 deg C, not 29.
 

I have now moved the sender to in front of the left footwell. The MAP sensor I only use as a barometer sensor before starting the engine so it will do its job just as good outside of the air box.
