Antilag is intended to increase the output of the turbo when the engine is not under load at launch or, optionally, between shifts. It does so by retarding ignition timing so that more of the combustion energy goes out the exhaust to spool the turbo instead of into moving the piston. Additional fuel may also be provided during antilag operation.
Enable antilag operation is an overall enable for antilag operation. If Enable antilag operation is unchecked, no antilag will be performed.
Specifies the throttle position above which antilag will be enabled. TPS values below this point will not activate antilag at all, regardless of the other settings below.
Specifies the engine speed at which antilag will activate at launch. This parameter is not used when antilag activates during a shift.
Defines the vehicle speed value at which launch control will be disabled. Below this point, the clutch switch input is ignored and ALS is activated any time engine speed and throttle position are above the set points. ALS operation is completely disabled for vehicle speed values between the launch and clutch cut points.
Defines the vehicle speed at which the clutch switch input is used to control ALS activation. If vehicle speed is above this point, then the clutch switch will activate ALS regardless of engine speed. ALS operation is completely disabled for vehicle speed values between the launch and clutch cut points.
Hold timing at specifies the ignition timing in degrees after top dead center that the ECU will hold when antilag is active.
Enrich fuel by specifies how much richer the mixture will be made when antilag activates.
The During shifts checkbox enables antilag opration during shifts. Antilag during shifts requires that the ECMLink clutch wire is installed.
Antilag operation interacts with the Launch limit and No Lift To Shift. Antilag's Activate above rpm should normally be set below the Launch limit rpm and below the Clutch cut rev limit rpm.
In cases where the engine's knock sensor is picking up and reacting to noises other than actual detonation, these knock sensor controls allow adjustment to restrict the application of ignition timing retard.
Activate above specifies the rpm above which the timing retard due to knock will be applied. 2200 rpm is a typical setting if the knock sensor is not reacting to anything but real knock.
And TPS above specifies the throttle position above which the timing retard due to knock will be applied. 0% is a typical setting if the knock sensor is not reacting to anything but real knock.
