16.14 Anti-Lag Switch
The Anti-Lag switch function allows turbo-charged vehicles to decrease the “lag” associated
with boost when the motor is not under full load.
There are 6 adjustable parameters:
Enabled / Disabled : This either enables or disables this function.
Retard Value : The ignition timing is retarded by this amount when the Anti-
Lag conditions for operation are met. The valid range for the
Retard value is (1 to 20)
°
ATDC.
% Inc. Fuel : The percentage of fuel increased during Anti-Lag operation.
The valid range for this function is (1 to 50)%.
Zero TPS ONLY : If the Anti-Lag function is to be used when the Throttle
Position Sensor value is zero then turn this function ON.
Otherwise select OFF.
Zero Inj Time : If the zero TPS only function is ON then this value determines
the amount of fuel injected at zero or no throttle. The valid
range is (1-16) mS.
Throttle Perc : The throttle position value below which Anti-Lag is
operational. The valid range is (5-80)%.
The anti-lag system is enabled by a switch connected to the Auxiliary Input/Output. Once
enabled, if the conditions in the anti-lag parameters are met, the anti-lag system will be
activated. In some systems the switch is activated by the clutch.
WARNING: DO NOT OPERATE ANTI-LAG FOR PROLONGED PERIODS.
EXHAUST AND TURBO TEMPERTAURES RISE WHICH MAY CAUSE ENGINE
