Switch activation can be triggered by either a physical digital input or using the Internal output system.






Enable or disable the Anti-lag function.


Activation method

How to activate anti-lag function.

Always active - Anti-lag functionality is always activated.

Switch input - Activation of the function requires the digital input function anti-lag enable to be activated.


Anti-lag timeout

Maximum amount of time the anti-lag function can be used.

Note: It's not recommended to anti-lag more than 3-5second unless you really know what you are doing.


Enable TPS

Minimum TPS to activate the function.


Enable RPM

Minimum RPM to activate the function.


Enable TPS

Minimum vehicle speed to activate the function.



Minimum CLT to activate the function. Safety function to prevent cold engines to be able to anti-lag.


Timeout RPM limiter

Used as a soft "cyclic idle" limiter for engines that can't control the anti-lag airflow with valves/e-throttle or throttle kickers. When the TPS and RPM has been below the set points for more than the anti-lag timeout time, this limiter is activated instead of the anti-lag. This is not needed when the ECU can control the airflow to bring the engine to a normal idle when the Anti-lag times out. Set the RPM at the rev-limit in those cases.


Air supply

To be able to anti-lag, the engine needs to get enough air to spool the turbo. Specifies where the extra air is from.

None/solenoid - Unuquie solenoid dedicated for this purpose only.

Idle control solenoid - Uses the idle air solenoid.

E-Throttle - Use the E-Throttle system.

Note: Anti-lag need a lot of air to build boost on low RPM with larger turbos.



Ignition adjustment/drop and fuel enrichment


Ignition control mode

Specifies the ignition control mode, retard current ignition angle or use a direct control ignition advance.

Retard (from main table) - Retards ignition angle from the current tables (including compensations).

Direct control (of final ignition angle) - Just put out a direct control of the ignition advance and do not pay attention to main ignition table or any compensation..


use below TPS

Use only the above Direct control (of final ignition angle) below this TPS value.


Ign adjustment

Ignition adjustment from main ignition table during anti-lag.


Ignition drop

Ignition drop (cut) event in percent during anti-lag.


Fuel adjustment

Specifies how much fuel to be adjusted during anti-lag.


Fuel drop

Specifies how much fuel to drop (cut) during anti-lag.






2JZ anti-lag settings with LS2 e-throttle body


Example main settings to use the E-Throttle to enable anti-lag.




Ignition adjustments from base ignition table.




Ignition drop. In the above example at 3000rpm (when TPS < 1%) 50% of ignitions will be dropped. <-- do not mix with ignition retard, which is not the same thing.

Note: the rev limiter cut type is used here, use sequential for a smoother limiting in Limits --> Rev limit.




Fuel enrichment during anti-lag, used to cool down the engine/turbo, here at 3000rpm 10% fuel is added to regular fuel table.
