anyone know this system?

[live4my4g63]

what is he running here, is it dsmlink and if so what setup is it and set to?

It's anti-lag on DSMlink.

 

[talondave]

Sounds like he has is set around 6k rpms

 

[93_tsi_fwd]

Could also be keydiver chip.

 

[DSM4me44]

He has it set to high if you ask me. I have mine set to 4500 and i get great launches. I had it set closer to 5200 once before and I could actually start to break my tires loose.

It's anti-lag on DSMlink.

I believe it's a 2 step, not antilag.

I believe it's a 2 step, not antilag.

I'll be the first to admit, I didn't know there was a difference. Could you explain the difference? I think people throw the word "2 step" around to much. I hear people refer to DSMlink's feature as a 2 step as well as an antilag. So since you brought it up, I was curious of the difference?

 

[cheap90gsx]

that's just the launch control. probably controlled by dsmlink.

Here's the description of anti-lag from DSMlink's old website.

Generically speaking, the term anti-lag refers to a technique commonly used by WRC style cars to quickly spool a turbo while the car is under hard deceleration in anticipation of the hard acceleration that's likely to follow. The technique involves retarding ignition timing so far as to cause the exhaust valve to open well into the power cycle, resulting in extremely hot and explosive gases rushing past the turbine, spinning the turbo up like crazy.

While we don't provide a full-on WRC style antilag system, we do provide a very effective drag style system that operates at the line and during those hard power shifts you make down the track. This helps to quickly spool the turbo for those pesky pro-trees and keep the turbo spooled in between shifts. Combined with the no-lift-to-shift feature, this can have a dramatic impact on 1/4 mile times.

The 2 step, also known as the stutterbox, is as cheap90gsx said - a launch control. It's a setting in DSMlink (and possibly other tuning methods) that you set your launch RPM and no matter how far down you push the gas past that RPM, it does not go past the preset value.

The stutterbox launch RPM is implemented as a simple fuel cut mechanism, exactly like the factory rev limiter.

Ya Shep uses 2step on his talon but it is at such a high rpm and AEM EMS is making it hit the limiter so fast that he builds crazy boost. This is breaking the rules because i heard this from a pretty knowledgable dsmer

 

[live4my4g63]

so how do you set 2step in dsmlink because i only know how to set the anti lag

 

[Redfwdsm]

ok not to change topic but why the hell is my post not in here anymore? whos deleting my shit?

 

[viperlp01]

a mod

 

[live4my4g63]

i havent seen your post on here and i havent deleted it out of here. i posted another one last night which i cant even find now.

 

[LandoAWD]

PMs are the proper way to deal with administrative issues, though I see no deleted posts in here.

 

[LandoAWD]

so how do you set 2step in dsmlink because i only know how to set the anti lag

Launch RPM box.

 

[live4my4g63]

so a good question would be could i run the same kind of thing that guy in the video is with dsmlink or is it going to be much more than that

 

[dsm_gsx97]

He has it set to high if you ask me. I have mine set to 4500 and i get great launches. I had it set closer to 5200 once before and I could actually start to break my tires loose.

Usually it is the higher the launch RPM the faster you are out of the hole. Hard to believe because it doesn't make sense but it is true. Years ago I didn't believe this much like you till an older member on a local board challenged me to lift my launch RPM and see if it changed my 60fts. Sure as "you know what" I dropped my 60fts from 1.9s to 1.7s just by launching at 6000RPMs. Then with a little practice I was popping off 1.6s in no time.

Even though your wheels are spinning, as long as they aren't bouncing you are good. Spinning tires is good...bouncing or non spinning tires is bad and usually ends up in breakage somewhere in the drive train.

Keep in mind my example is at the track and not on the street and you are more likely to spin and not break on the street compared to a well prepared track which is why things have probably worked ok for you. 4500RPMs is ok for launching in the street as long as you get those tires spinning, but bringing it up higher wont hurt you and might save your center diff.

Answering other posts on this thread...

FYI Shep launches at 10K RPMs.

2Step is just a rev limiter set to a lower limit which is activated by a switch. It limits fuel and spark at a certain RPM which causes that sound with how it cuts. AEM is nice because you can control the cut of the 2step (like how many RPMs between cuts) where as DSMLink does not give you that control. You can tell a DSMLink 2step over AEM any day because of how slow the cut is. It is like a 300-500 RPM cut. I use a 50RPM cut and shep uses no cut as an example.

Anti lag is a way to build boost at the line or in between turns. It achieves this by retarding timing and adding more fuel than normal. This allows fuel to make its way into the exhaust ports before being ignited. Once ignited it sends huge amounts of exhaust pressure (sometimes still flames) down the exhaust manifold causing the turbo to spool faster. Rally cars that have this system use titanium turbine wheels and go through them like crazy because they are getting burned up with the anti lag.

Setting up 2Step in DSMLink is just under ECU-->RPMs and set the launch RPM. If you wire in a clutch switch you can use NLTS and set that there too. I had both my launch and NLTS set at 6KRPMs and had worked very well for me before I switched to AEM in my cars.

Sorry for the rant, but it has been a while since I posted on here (like 6-8 years) and I figured if it was going to count as a first post again I might as well make it worth it.

 

[LandoAWD]

Old school!

 

[tkelly27]

Yes, if you get link, you can edit at what RPM your car holds at on the line. You simply give the car 100% gas, and let the clutch out and go.

You can get a chip to do the same thing, but you won't be able to change what RPM it happens at, or actively change the tune.

 

[live4my4g63]

thanks dsm_gsx97. so your saying in order for my 2step to be as quickly cut in that video it will take aem. and is anti lag going to be the fastest sounding cut using dsmlink?

 

[snowborder714]

My question is what are you looking for? Just the sound??

Most people on here don't use anti-lag. More people use the 2 step. I don't believe it will be as fast as the one in the video. And anti-lag sounds very different than the 2 step.

I could probably take a video of my car at different RPM's on the 2 step as well as what it's like with anti-lag this weekend if you'd like.

 

[live4my4g63]

yes i would like that thanks. and yea im wanting it to sound like that because i dont really like what the anti lag sounds like.
