Pull a plug wire.

Take your spark plugs and bash each tip with a hammer and you're done.
But no let's be serious. You're misfire system is known really as the anti lag system. It basically dumps a lot of fuel while retarding timing so the unburnt fuel will enter the turbo and burn there, keeping it spooling. If you're asking how to run a "misfire system" I think it's safe to assume you can't afford to use it since it'll kill your turbos really fast.

Damn and to think I spent all that money replacing my entire ignition system! I didn't realize that what I had was a perfectly good misfire system!

There is also a 2 step(dsmlink and chipped eprom) that is totally different than anti-lag. 2 step kills spark to random cylinders(similar to rev limiter) that has no effect on turbo life or performance.

First off, do a search on here for "anti lag." Lots of threads pop up, although be careful. There is a big difference between a true anti lag system (ALS) and drag racing anti lag (like a 2-step). ALS will keep the turbo spooled off throttle, as seen on rally cars and the reason they pop and crackle so much. Drag anti lag doesn't build boost off throttle.

Two ways that I know of, how you can do it:

1. Jack open the throttle (never let the throttle close), inject fuel and retard the timing to say 20-30 degrees BTDC. Set up correctly, it should keep the turbo spooled all the time. How you go about getting the throttle to stay open, injecting fuel and retarding the timing are up to you, although a standalone would definitely come in handy for that.

2. Divert some compressed intake air straight to the exhaust manifold and dump in fuel. Same thing as above, only basically taking the engine out of the equation.

Either way, you are going to create a lot of heat and stress in the exhaust system/turbo. Rally ALS can (and will) kill a turbo eventually. How you set up the system and get it working is up to you. New WRC cars have very advanced systems, but its hard to find a whole lot of detailed info on the web. True ALS on a DSM would be pretty interesting, and who cares if you go through a lot of turbos, just buy another 14B for $100

I wish I could replace my turbo for $100 but unfortunately, I exceeded that 6 yrs ago. For that very reason, I will just stick with 2 step and stay away from anti-lag systems.
