boost control (closed loop)
target tables
Specifies the target tables to be used for the selected boost strategy.
•Single table - One boost duty table available.
•Dual table (switch activated) - Two boost duty tables available, switchable by triggering the digital input function Boost target switch (use table 2).
•Triple (switch activated) - Three boost duty tables available, switchable by triggering the digital input function Boost target switch (use table 3).
•Triple (controlled from MDash) - Three boost duty tables available, changeable in the MDash android app, see MDash boost selector.
target boost reference
Reference of the boost tables.
•Target map (above absolute vacuum) - Target is a given value, ex 250 = 1.5bar overboost pressure.
•Boost pressure (above air pressure, sea level) - The target pressure is the amount of pressure to add above sea level ambient pressure (roughly constant power at different elevations).
•Boost pressure (above air pressure, current baro) - The target pressure is the amount of pressure above current BARO pressure (constant amount of relative boost pressure).
boost ramp
Boost ramping controls how quickly the target boost value can change, helping to avoid sudden spikes or drops that could cause instability or traction loss.
This ensures controlled, progressive boost transitions and better drivability across all operating conditions.
boost ramping
Specifies how the boost ramping (limitation) should be applied when the target boost changes.
Used to control how quickly the system is allowed to reach the new target boost level, either through a fixed rate, gear-dependent ramping, or a fully dynamic table.
•Disabled - No closed-loop control. Used for initial tuning of open-loop tables.
•Fixed - Closed-loop active with a fixed ramp rate.
•Gear based - Ramp rate varies by gear.
•table - Fully configurable ramp rate from a dynamic table.
ramp direction
Specifies when the ramp limit is applied:
•ramp both up and down - Ramps boost in both directions.
•ramp only up, instant down - This will limit the positive ramp and "snap back" to the correct target while on deceleration or liftoff. It can be used to make large turbo setups more forgiving, but if you lose grip at full boost and pedal, the target boost will only decrease at the same rate as the boost ramp..
Target boost ramp rate
Specifies the rate of the target boost to be increased/decreased, specified in kPa per second. Set to 0 for instant = no limit/ramp.
Boost targets
Description
Name of the boost level. You can name it freely. If using MDash boost selector, this name appears in the MDash switch.
