Secondary PWM settings (Boost alternate)
The Secondary PWM output is a simple table based output. Can be used for Boost control, water injection or other purpuses.
Two modes of operation:

Absolute: The table axis are RPM and MAP.
Relative: The table axis are RPM and (MAP - target_absolute_pressure). "Target absolute pressure" is also frequently called "boost-target" (see "boost vs RPM" and "boost vs TPS" dialogs), and can be effected by TPS, or anytrim, therefore useful for protection against hazards (for example EGT too high => reduce boost). To use external analog input (even a variable resistor potentiometer to adjust boost to racetrack-grip), you can use anytrim on boost target (which has no effect in absolute mode).
