IAT Sensor
OK - this one's for the brainiacs:
How does the ECM adjust the pressure/timing of the injectors according to the input from the inlet air temperature/pressure sensor? Specifically, hotter inlet air causes shorter injector pulse, higher intake tract pressure (pre-turbo of course) lengthens cycle time of injectors, etc.
Basically, I need to know what effect the IAT has on the ECM's fuel map.
