Group N Anti-Lag with Cyclic Idle (Throttle permanently bleeding extra air)
Group N regulations prohibit the use of air bleed valves or other devices providing the same effect, therefore the throttle must be permanently cracked open (typically between 15% and 25%). When setting up for this mode, the Anti-Lag must always be armed and cyclic idle must always be on.
·Anti-Lag System Arming = Always ON
·Cyclic Idle Mode = Always ON
·AL Enable RPM = 3000 RPM
·AL Enable TP = 60%
Operation:
Turn the key on, the engine will be running with cyclic idle and anti-lag armed but not active. Drive to the start of the rally stage, give the throttle a stab to exceed 3000RPM and 60% throttle, anti-lag will become active. Anti-lag will remain active generating turbo speed until the engine speed (RPM) and throttle position (TP(Main)) have been below their enable values for the time specified by the AL Deactivation Timeout. Drive the stage. On completion of the stage the engine will be idling with cyclic idle.
Anti-Lag RPM/TP Activated (ECU controlled air bleed)
No cyclic idle and the user requires Anti-lag to be activated via engine speed (RPM) and throttle position (TP(Main)). Extra air is only bled into the engine via an ECU controlled solenoid when the Anti-Lag is ON.
·Anti-Lag System Arming = DI
·Cyclic Idle Mode = OFF
·AL Enable RPM = 3000 RPM
·AL Enable TP = 60%
Operation:
Turn the key on, the engine will be running with a normal idle. Flick the switch connected to the appropriate DI to its ON position, anti-lag will become armed. Drive to the start of the rally stage, give the throttle a stab to exceed 3000RPM and 60% throttle, anti-lag will become active. Anti-lag will remain active generating turbo speed until the engine speed (RPM) and throttle position (TP(Main)) have been below their enable values for the time specified by the AL Deactivation Timeout. You can turn the anti-lag off at any time by flicking the switch to its OFF position. Drive the stage. On completion of the stage the engine will be idling normally.
Anti-Lag Switch Activated (ECU controlled air bleed)
No cyclic idle, and Anti-Lag becomes active only by using the Digital Input. Extra air is only bled into the engine via an ECU controlled solenoid when the Anti-Lag is ON. Set the AL Enable RPM to 500 to ensure it’s always OFF during cranking.
·Anti-Lag System Arming = DI
·Cyclic Idle Mode = OFF
·AL Enable RPM = 500 RPM
·AL Enable TP = 0
Operation:
Turn the key on, the engine will be running with a normal idle. Drive to the start of the rally stage. Flick the switch connected to the appropriate DI to its ON position, anti-lag will become active. Anti-lag will begin generating turbo speed. You can turn the anti-lag off at any time by flicking the switch to its OFF position. Drive the stage. On completion of the stage anti-lag will still be active until the switch is set to the off position.
Warning:
This mode requires careful control over the activation switch at the start and end of the stage due to the possibility of excessive anti-lag periods.
Anti-Lag RPM/TP Activated with Cool Down (ECU controlled air bleed)
One method is to only use Cyclic idle in “Cool Down” mode meaning it only becomes active when Anti-Lag switches from ON to OFF.
The user arms the Anti-Lag system via a switch. At this point the solenoid is OFF (no extra air) and the cyclic is Idle is OFF. The Anti-Lag then switches ON (from RPM/TP activation) and the solenoid activates bleeding air into engine. At some point Anti-Lag switches OFF (from RPM/TP timeout). The solenoid remains ON and cyclic idle is required to limit engine speed. The system is now running in cool down mode for the time specified allowing exhaust temperatures to reduce.
·Anti-Lag System Arming = DI
·Cyclic Idle Mode = Cool Down
·AL Enable RPM = 3000 RPM
·AL Enable TP = 60%
Operation:
Turn the key on, the engine will be running with a normal idle. Flick the switch connected to the appropriate DI to its ON position, anti-lag will become armed. Drive to the start of the rally stage, give the throttle a stab to exceed 3000RPM and 60% throttle, anti-lag will become active. Anti-lag will remain active generating turbo speed until the engine speed (RPM) and throttle position (TP(Main)) have been below their enable values for the time specified by the AL Deactivation Timeout. After this deactivation timeout has been exceeded the ECU will continue to bleed extra air into the engine and apply cyclic idle to hold the engine speed. The extra air and cyclic idle will turn off after the Cool Down Timeout has elapsed. This allows extra air to be pumped through the exhaust cooling the system down. You can turn the anti-lag off at any time by flicking the switch to its OFF position. Drive the stage. On completion of the stage the engine will running with cyclic idle for the period specified by the Cool Down Timeout, following this the engine will return to a normal idle.
