MODES
Altitude
The engine will transition between EGR and boost mode at an altitude of 6500 ft. Altitude is
determined by the Barometric Pressure Sensor located on the engine. See Figure 2-3.
Condensation Protection
In very cold ambient (i.e. < 30F) conditions the engine will operate in a "condensation protection"
mode. EGR is disabled during this mode requiring a slower turbo speed. The engine will sound
"different". During this mode of operation the operator will notice a lower "boost" reading
compared to when EGR is active, however there is NO reduction of power.
