Running -10 degrees during launch control gets my huge Holset to about 7 - 8 psi in neutral

Should do it.

You can do better than that. ;)

Not technically true antilag, but it does the job when launching

You realize only one of those videos is anti-lag and the rest are people who don't realize that super rich deceleration fueling does not equal anti-lag?

Those WRX/STI/EVO are not anti-lag. They are poorly tuned on decel which does nothing for you.

Better than that? Bro I moved a diesel turbo to 8 psi in that little bit.

Its technically launch control with spooling... but I have anti-lag too (also referred to as flat-shift) which does what you saw in my video between shifts like WRC cars and the like. But, thats not practical and it murders turbos - I have no reason to shoot fire every time I shift ;)

thats not anti lag. its called a 2-step launch control.

Ok - and the videos the sir posted after mine was called poor tuning during decel.

I have 2-step. I also have anti-lag.

Spocknasty · 07-02-2007, 02:14 PM

I am aware not all were anti lag. I was referring to the snap crackle pop you were emitting from your exhaust.

which is a function of 2-step. Don't link me to stupid people running horrible decel tuning, nothing makes me angrier.

den9 · 07-02-2007, 05:24 PM

that first video with the suzuki, look at his rpms, well it looks like a boost gauge the way moves

dolphinS4 · 07-02-2007, 06:53 PM

I was check'n out your car at AWE a couple weeks ago.
Nice job.

Thanks man.

Yeah I was having ECU issues that day, if you were there when I left, you could tell haha. All squared away now.

Can someone explain to me what a 2-step is?

A pretty much a lower rev limiter that you can launch out. Makes launches easier/more consistent. Thats the best I could do explaining it. Many people call it 2 step, stutter box, launch control, etc.

You program the rpm you want it to hold at, so you don't have to concentrate on holding your rpms manually.

redline · 07-02-2007, 09:43 PM

Is this a true Anti-Lag like the rally cars run? Does it feed air to the manifold? I dont fully understand how it works.

teh DIRT · 07-02-2007, 09:44 PM

So maybe its not the antilag we are all used to, but its the same principles of timing adjustment. Cool stuff man, dont let everyone discount your work.

1st move video of the 5series please,
and 2nd someone can chime in if im not explaining it well enough,
a 2step is a launch control feature, you can preset a determined launch RPM, so you can pin the throttle and the RPM will not go any higher then you have it set at.
Most aftermarket ECU's have it built in, I know it was a function of my old hondata

I'll get more video once my other engine is done.

You explained it well enough. There are a few terms: anti-lag (flat shift), launch control, etc.

Antilag/flat shift is when you hear popping/fire between shifts ala WRC cars - basically whenever the clutch pedal is grounded (clutch switch) the car enters flat shift and it retards the timing so you can keep the throttle pegged and shift without lifting throttle, keep the turbo spooled between gears, etc. I don't run this because I don't have a rally car and this is HELL on a turbo/manifold

Launch control is basically the same thing except you only do it while launching - thats why I term it antilag/etc. So what happens is I hold a button on the dash, I have preset the "retard" rpm to be 2800 rpm - this sets the timing to -10 degrees (or 10 atdc). The engine will work to keep the RPM there, and it will make power to rev up, and this is when it enters "hard cut" which is 3000 RPM - this actually cuts spark (not fuel) to keep the engine below 3k but above 2800. If you cut spark and fuel you drop your boost because you're no longer keeping energy thru the turbine.

Some launch control can have traction control integrated - mine does not.

To get a real definition of antilag please read this:
http://en.wikipedia.org/wiki/Anti-Lag_System

As SoStock92 has said though, true antilag extremely shortens the life of the turbo and manifold. Duh, it is creating explosions in the manifold and turbo. It is simply unnessesary and will cost you way too much money for a street car. A 2-step aka Launch control still puts added stress on the turbo and manifold, but is activated much much less. When you have a large turbo without massive amounts of displacement launch control is great/ almost nessesary.
