Anti-lag System (ALS) is a method of reducing turbo lag or effective compression used on turbocharged engines to minimize turbo lag on racing or performance cars. It works by delaying the ignition timing and adding extra fuel (and sometimes air) to balance an inherent loss in combustion efficiency with increased pressure at the charging side of the turbo. This is achieved as an excess amount of fuel/air mixture escapes through the exhaust valves and combusts in the hot exhaust manifold spooling the turbocharger creating higher usable pressure.
It's done through the various means:

1.Throttle bypass, or throttle kick ALS.

2.Secondary air injection, or inlet bypass.

3.Turbo and intercooler bypass D-valve.

4.Ignition Retard & Fuel Dump (WOT).

5.Using an MGU-H (Motor Generator Unit - Heat) to eliminate turbo lag.

Thanks for watching 👌🏼
