61. Boost Parameters
The GEN3 ECU allows the user to control boost parameters in two (2) modes: Staged or Pulse Width
Modulated (PWM).
Staged mode turns on boost stages (solenoid valves) in a user defined, time sequence. PWM mode
assumes the boost system is configured with a PWM boost valve. When the PWM mode is enabled
the Stage 1 – 3 timer input windows are made inactive, as shown in the screen print above. When
Staged mode is selected, the Stage Timer input windows are active as shown in the screen print below.
