7.6 Boost / VVT 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL
7.6.2.4 Other Boost Control Settings The following settings remain:
• Boost Table Switching - This option when enabled allows a switch input to be configured which switches
between two different boost duty or target tables. You can also allow it to switch tables based on gear by
selecting “Gear-based”.
• Boost Table Switching Gear - If boost table switching is set to gear based, the MS3Pro will switch to the
second boost table when you shift into this gear and above.
• Boost Timed From Launch - If launch control is enabled, this setting allows a specific boost duty or target
to be used for a set amount of time after launch.
• Specific Launch Duty/Target - If launch control is enabled, this setting controls what target (closed-loop) or
duty (open-loop) is used for boost control.
• Launch Boost Duty - This is the duty used by Specific Launch Duty/Target, if using open loop boost control.
• Launch boost target - This is the boost target used by Specific Launch Duty/Target, if using closed loop
boost control.
• Boost by speed / gear - this item enables the use of the boost vs speed curve. You may set it to use one of
two speed sensors if enabled.
• Above TPS % - This setting is used in conjunction with the Boost vs Speed function. Below this TPS setting,
the normal boost tables are used. Above this TPS setting, the boost vs speed curve is used.
• Per Gear Targets - Specifies the boost target in each gear if boost by gear is active.
7.6.3 Boost control duty table
This is the table you use to tune open loop boost control.
To tune this table, start with small values (the default table is all zeroes) and increase the numbers until you
reach the desired amount of boost. Use open-loop boost control to try out different frequency settings and find the
settings that work the best for the particular solenoid being used. We recommend using open loop boost control
to establish that the boost control setup is working before you use closed loop control.
The second duty cycle table (Boost control duty table 2) can either be used for switched boost or a second
wastegate.
7.6.4 Boost control target table
When using closed loop control (either single solenoid or dome pressure), this table specifies what boost level to
target in kPa as a function of throttle position and RPM.
