dont think so

 

No they are completely different.

2-Step = A lower rev limit at the flip of a switch/push of a button etc. That one would use when launching their car to get their turbo to spool up, or for N/A applications it allows for the 'perfect' launch everytime once you find the right rpm to launch at.

Anti-Lag is what causes all the rally cars you see on TV to backfire all the time, their turbos are constantly being spooled even when they are off the gas, you can read how in the link you provided.

 

well it sounds like the same thing except with out a rev limiter

 

any back fire is not good for your car. Those rally cars are sponsored out the butt...just like 8-9 second engines that get replaced after a certain amount of runs, I don't think those rally engines can take hours of that kind of abuse.

 

2-step is nothing but an ignition cut rev limiter.

Anti-lag keeps sparking but massively retards the spark so it ignites the mixture after the exhaust valves open and pushes the combustion event out into the exhaust manifold and turbine. Spools the turbo really nicely but a little rough on your exhaust system and turbo.

 

that is true it uses the burnt fuel to fuel to spool it.
