The antilag option makes your car run really rich. I had mine set up at 3200 rpm and it build 15 lbs of boost.

It make you run "rich" on purpose. The way AntiLag works is by retarding timing so much, that the fuel actually doesn't spark until it is leaving the combustion chamber. This in part, sends a GIGANTIC ball of flame past your turbo. That flame is what spools the turbo, and then you read rich because some of it may not have been burned off by the time it passes either your front O2 or a wideband.

2 important things to note:

1) You don't want to stay on antilag for too long because it will actually soak your spark plugs and then they won't spark until they dry off.
2) You can seriously wreck your turbo if you use it too often or recklessly. (Think of it this way. If a ball of flame got shot out your butt, it would start to cause harm to things too ).

When you use antilag, you just want to ease into it. You don't want to just slam the gas down to the floor or you'll get alot of detonation. Also, go into the miscellanious section of dsmlink and set your CEL to come on at 2 deg. of knock to keep things safe. If you CEL light flashe's, get out of the go pedal. You'll also want to log while you're gettting the antilag set up so you can see what's going on.

Get used to all of the option's and do alot of reading and research before you start tuning on that bad boy. Get all your fuel trim's set up first and foremost and then you can start really digging in and making some good power. Shoot me an IM if you've got any question's and I'll help as much as I can. Dsmlink has been a huge learning experience with me but nothing beat's tuning your own vehicle and getting it to make some good numbers. There's a few member's on here that will most likely be more that willing to help.

Yup. Someone else should've told my buddy....he never listens to me.

That was the picture I had in my head when I wrote that. What were the specs. on that turbo?

TD05H 20G. One of my DSM'ies from Maryland is an absolute wildman and loves to sit at stoplights and AntiLag his car to death. This is the result.

In my experience, antilag isn't necessary unless you are running something along the lines of a GT35 or bigger. Anything else really isn't necessary. Use the stutterbox function to full advantage. Find that magic RPM point where the tires still have full grip, for me it's 5500RPM. Also, nothing works better than the no lift to shift, if you haven't done the wiring necessary to use that function, take the time and use it! Shooting flames out the exhaust is cool, but running a lower e.t. is cooler. Also, like fulanititoo said, use the DSMLink Forums. They're the best.

the antilag you guys are talking about is the one that keeps boost between shifts, right?... or the 2 step (launch control)??

That is NLTS (no lift to shift). That is also called a 3 step.

Antilag is basically where DSMLink richens the mixture and retards the timing so that the air/fuel mixture is still burning when it exits the cylinder head and enters the turbo. The reason for this is that on a larger turbo, it takes more energy to get the thing spinning to the RPM levels where it makes boost. As you can see from the posts above, it should be used with moderation.

if i set my antilag up at say 3200 rpm what happens when i'm two stepping at 5500? does the antilag stay on? or does it disegage? i'm kinda new to the whole dsmlink

Thats not a good idea. If your two step is set to come on at 5500, you should have your antilag turn on around 5250. A good rule of thumb I was told, and found to be a very good idea is to have antilag come on just before the two step. The incriments of DSMLink are 250, so as I said above...

If you have the antilag come on at 3200 and twostep kick in at 5500, you have 2300rmps where fuel is being dumped into the turbo. All this is going to do is shoot fire out of the tail pipe.

As far as NLTS, that basicly acts as a rev limiter for the car. When you push the clutch in, a signal is sent to the ECu, and a preset revlimiter is enacted. If you have it set to 5000rpm, when you push in the cluch, your RPMS will bounch around 5k, until the clutch is released.

Hope this helps, and if you have DSMLink, get on the DSMLink forums, you will not find a better, group of knowledge without the BS.

thanks for the info...but how does the antilag turn off??? like if it comes on at say 5250 when does it turn off??? i think it turns off by the clutch switch...am i right?

Also what should i set the settings to like what should i set the timing to and how much should i richen up the fuel?

For anti-lag during a launch it will turn off when your car is going faster than 7mph unless you changed the default setting.

For anti-lag during no-lift-to-shift it will turn off when you release the clutch pedal.

Anti-lag is separate from the 2-step and NLTS. Both of these features can be used without Anti-lag turned on and function great. Use the Anti-lag at your own risk. I have my 2-step set at 5500 and when I use the anti-lag set to engage at 5250 my Big 16G spools up 18psi while I sit there and I'm terrified for my center dif. to launch at that boost level.

dam that would be one hell of a launch 60 trim at like 25-30 psi ....i better go buy some drag radials

bring back an old post but i wanted to share some extra info.

Some good info on different types of anti lag systems:

Brewed Motorsports: Turbo Anti Lag system aka ALS

Haven't been able to view the forums for some time now (looks like my houses Bangkok IP address is banned?)

Any way built this set up for the S13 while i was back in the states this winter.
I also have a couple video clips i'll post up soon.

Now that's a legit antilag setup /\/\

Antilag on my Vr4

What's ur timing & enrichment set at

Sent in PM as well but for anyone else curious I think 10.1* ATDC and 0% enrichment but that was over 7 years ago and I can not find any logs older than 2010 on my laptop.

was this a billet alum wheel or an Inconel? the titanium aluminide wheels where the ones made to take the higher heat caused by antilag(on the mitsu turbos anyways)

Inconel...but the ti wheels are less-tolerant of foreign object strikes and the cost is much greater, so they're typically not a good choice for street cars.

A billet aluminum turbine would fail the first time it made boost being that the melting point of aluminum is around 1200*f.
