7.6 Boost / VVT 7 ADDITIONAL ITEMS: BEYOND BASIC FUEL AND IGNITION CONTROL
• Maximum RPM - Anti-lag is disabled above this RPM.
• Maximum MAT - Anti-lag shuts down if the air temperature goes over this point.
• Maximum ALS time - The longest allowable time, in seconds, for the anti-lag system to operate.
• Time between activations - This is used to prevent a brief sensor reading out of the anti-lag range from
resetting the anti-lag timer. The MS3Pro treats any set of activation conditions in this time block as a single
activation, even if it briefly comes out of the TPS or other conditions that would activate anti-lag.
• Minimum CLT - The lowest coolant temperature at which anti-lag can be used.
• Maximum CLT - Anti-lag is disabled above this temperature.
• Enable cyclic fuel cut - If this is turned on, the anti-lag system will use a rotating fuel cut when active.
• Enable cyclic spark cut - Cuts spark when the anti-lag system is active.
• Enable roving idle fuel cut - This uses a secondary fuel cut to reduce idle speed. Roving idle fuel cut is
active when anti-lag is off.
Note that cyclic fuel cut and roving idle fuel cut only work with full sequential fueling. They do not work in semi-
sequential or batch fire fuel modes.
• Use idle valve - If set to on, the idle valve will open an additional amount when anti-lag is active.
• Idle valve duty - The amount of extra duty cycle to apply to a PWM valve if the idle valve is active.
• Idle valve duty steps - Like the above setting, but for a stepper IAC valve.
• On/off output - Allows you to activate an on/off output when anti-lag is active. Use this setting to specify
which pin.
• PWM output (generic PWM F) - Allows you to turn on a PWM output when anti-lag is active.
• Output port / pin - Specifies the output pin for the PWM output.
• Output duty - The PWM output is driven at a fixed duty when anti-lag is active. Use this setting to specify
what duty cycle.
• Frequency - Specifies the frequency to use with the PWM output.
