2 step for launching from a stand still.
anti lag for full boost between shifts.

So a 2 step is just a module of sort? What about anti lag?

You use a 2 step for staging, and anti lag to launch the car. Only rally cars use anti lag for keeping spool up for between shifts.

A 2 step keeps the rpms constant irrelevant of all other things (not interested in building boost). Anti lag keeps the rpms constant but also builds boost to aid with spool.

There are anti lag and 2 step modules, and ECUs that have these limiters already in place if you'd like to set them up.

Good thanks, the rally anti lag is what I'm interested in from what I have been reading there is also 2 different setups a rally and a drag setup. Rally being a bit more complicated but I can't find extensive info as to a parts list and install and setup info. Any info you can offer is great thanks guys

Not entirely true...Rally cars do use it...but they are not the ONLY ones that use it. Several guys around town here in AZ have rolling anti-lag setups that they use for roll racing...

Rolling anti lag is used before you start accelerating to keep the boost up (it also keeps you at exactly the speed you're going whenever you depress the switch to enable it, which is very helpful), it does not automatically enable itself in between shifts after you go WOT.




hex: I don't think I've seen any threads, here or on SF, which detail how to enable antilag between shifts. To be honest there's so few people that would use it you're going to have a hard time finding solid info on it.

^^ right, you can usually set a RPM trigger that enables it and then it is activated with a switch...

atleast thats how ProEFI works...

 

[SideWinderGX]

Activated with a switch, and as soon as its activated it'll hold whatever rpm you're at. It'll make whatever boost you have as the setpoint. Super easy, no setup required other than a switch and some wire back to the ProEFI.

I haven't been able to locate anything either, this is going to be harder then I thought.
