Switch activation can be triggered by either a physical digital input or using the Internal output system.
Anti-lag
Enable
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 Speed
Minimum vehicle speed to activate the function.
Min CLT
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 - Unique 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.
cooldown
MaxxECU offers a Antilag cooldown active RealTime Data value for this purpose to be used as a source axis into extra tables.
Allows for separate throttle targets and fuel drop, so regular "cyclic idle" can control the engine speed and cool the exhaust system with fresh air.
Timeout/cooldown 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.
Cooldown below TPS
Enables the cooldown RealTime Data to be active below this TPS value.
Cooldown mode
Run indefinite or use a timeout value to stop the cooldown after a certain time.
•indefinite - Will run indefinite.
•Set time - WIll run until the set time runs out.
Cooldown timeout
Specified how long the cooldown RealTime data value will be active, and specified in seconds. Available setting when the above cooldown mode is set to set time.
Cooldown air adjustments
Specifies whether to use the air adjustments table during cooldown.
Cooldown ignition/fuel adjustments
Specifies whether to use the ignition/fuel table during cooldown.
Example how to setup
1. Basic anti-lag setup.
2. Basic timeout/cooldown settings.
Which basically means, when anti-lag timeout has passed, the realtime value antilag cooldown active gets active, and you can do whatever you want with this RealTime data value within the MaxxECU to activate certain features.
3. To raise the idle during the cooldown, add a 4D axis to the added air table, and give it some extra %.
4. Anti-lag fuel drop when cooldown is inactive. No fuel drop here.
5. Anti-lag fuel drop when cooldown is active, 30% fuel drop here.
Example logview with a working anti-lag and cooldown feature.
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.
Examples
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.
