Haltech E11/E8 Instruction Manual
Launch Application of anti-lag is to help build boost when the throttle is open but the engine is not
loaded. This is achieved by enriching fuel and retarding the timing under these conditions, to raise
exhaust flow to the turbo. The engine speed is controlled to the desired RPM by dropping injection events
in a ‘rotation’ between the cylinders.
Launch application of anti-lag will begin when the car is below a certain road speed, the throttle position is
above a certain percentage and the ‘Anti-Lag Launch App Switch’ digital input is on. This digital input is
needed for it to work and is usually setup like a clutch switch.

Settings
Launch Start RPM Cut - The minimum desired RPM to launch to vehicle. Rotational fuel cut begins at
this RPM.
Launch End RPM Cut - The maximum desired RPM to launch the vehicle. Fuel is hard cut to all cylinders
above this RPM.
Fuel Enrichment - The percentage enrichment of fuel when anti-lag is on. Extra fuel is added to help
reduce combustion temps.
Absolute Ignition Retard - The ignition timing in degrees after top dead centre when anti-lag is on.
Min Coolant Temp - The anti-lag will only work above this coolant temperature.

Warning: Using anti-lag on your engine can cause overheating of engine, exhaust
system and valve train. Additional stresses on engine and driveline can cause
damage and possible failure of gearbox, drive shafts, differentials, clutch and or
crankshaft. Only experienced operators should attempt to use this feature.
