I have the Mac brand "normally open?" (max boost at 0%) solenoid, and have been using the fixed duty cycle control.

I'm interested in using the gear based target boost, but I am unable. It seems the Pressure vs Duty cycle table is configured in such a way as to make it impossible to use this type of solenoid. The numbers have to scale up from left to right, and with this solenoid, the relationship would be inverse.

Is there some kind of settings that can be changed to modify the way this type of boost control works, so that I can use this solenoid? I'm starting to think I have to have the other kind of solenoid, but would prefer not to if I don't have to.


I would like to alter the calibration to represent a relationship to the blue line

The 'normally open' / 'normally closed' setting will do this for you. You don't need to change the duty cycle table slope.
