Is Anti-Lag Illegal?

[karma_syke]

Turbo and intercooler bypass (D-valve)

A method by which a large zero cracking pressure one-way check valve is inserted just prior to the throttle body, enabling air to bypass the turbo, intercooler, and piping during periods where there is negative air pressure at the throttle body inlet. This results in more air combusting, which means more air driving the turbine side of the turbo. As soon as positive pressure is reached in the intercooler hosing, the valve closes.

Sometimes referred to as the Dan Culkin valve.

When used in a MAF configuration, the D-valve should draw air through the MAF to maintain proper A/F ratios. This is not necessary in a speed-density configuration.

thats pretty cool, very passive system, wonder how well it would work.

does it matter if its legal or not? why bother installing an anti-lag system unless its a track/rally dedicated car??

..it aint gunna get you to westfield any quicker.

Evos have factory antilag, but having it on anything else would be impossible to get engineered short of a drive cycle test, in which case it wouldnt effect the reading(depnding how it was setup)

...Strange eh.

tmk they have the air bypass hardware but not the required ECU mapping.

I can't imagine any manufacturer that offers warranty leaving this "feature" enabled.

I setup antilag on the Vipec for shits and giggles (it's not 100% setup as I'm not that keen on it). Definetely not good for your car though.

You sure Evos have it from factory? What models? I've never heard that before that's all.

You mean proper antilag for between gear changes or just launch control antilag? (I wrote up a post in the past explaining all the different things people refer antilag to but can't be bothered finding it).

How did you set it up exactly? I heard they install a fuel injector or something into the exhaust mani?

Have you also setup the launch control or flat shift?

AFAIK All evos after 3 have factory antilag except ADM's, not sure which ones are turned on, but RS's Tommy Makinens and Rallyarts have it on.

Nah you don't install an extra injector. It just retards the timing by a huge amount and opens the injectors to create a lot of unburnt fuel so it can ignite in the exhaust manifold. It's all just settings in the ECU.

Have you also setup the launch control or flat shift?

Nah havn't done that yet. Launch control is something I want to setup in the future though.
