Boost control PID
The Boost PID controller controls a PWM output by a PID controller to set the manifold air pressure to the target value(Boost target).
Boost target can be set 2 mode: gear dependent or no dependence.
- It means the 2 different mode uses 2 different table settings (located under this dialog in the menu system).
- Boost target= target table/curve * RPM Scaling - MAT & EGT reduction, see: BoostTarget Expression Grid
- Boost target can set by table (or curve) and by RPM scaling.
- The target has safety reduction settings, located in "Base setup menu" / "Rev limit/ Overrun/ Safety"
The PID reference DC comes from RPM dependent table( or curve)
- The reference DC can be set in 3 mode: gear dependent, speed dependent, or no dependence.
- It means the 3 different mode uses 3 different table settings (located under this dialog in the menu system).
- (If set to speed dependent mode, target has no dependence)
- The reference DC can reduce by MAT/EGT limit too if enabled.
Tps weight for ref dc:tps weight for refDC is to reduce(or eliminate) surge at high rpms and low tps.
If you have drag car only, you can put 0, but for street car it's recommend 15-30% (spool better with 0%). And control of car when starts to lose tracking is better. Because if you little release throttle ,waste gate would open more=> less boost.
