Anti-Lag System?

[Nexus1155]

Is it possible/worth it to do with our cars/turbos... TECH DISCUSSION.... GO!

[raketeS4]

elaborate please?

tossing up a reference link... heres for people that don't know about it... http://audizine.com/forum/showthread...light=anti+lag

is it true anti lag pwns turbos faster than normal conditions?

i want a 2-step setup.

[imola_Jon]

K03s barely have any lag as it is.

[Das General]

haha ya thats true...but maybe for a gt28 kit.

[Nexus1155]

yeah anti lag will wreck the turbos faster, two step would be cool, and i know K03s have barely no lag, but the name does not imply what all of it does...

If you wanna shoot flames out the back chip your car, run no cats, real downpipes, and straight pipes out the back. Honestly, antilag is quite silly on a car like ours. It would be possible though.

You can do an anti-lag system with any turbo's and piston engine. Standalone management is the only real requirement. Basically, all you're doing is retarding the timings.

if youre shooting flames does it melt anything on the car/heatshield?

My A4 1.8t running stand alone which is the only way to do a "anti-lag/launch control" setup on our cars.

[Das General]

ya...and your car is insanely fast. = )

Sounds like you have a 2 step rev limiter.. that's awesome man. I did hear some compressor surge though?

By the way... who tuned your car? Did the tuner re-use some of the values off the stock ecu, or did he just straight up tune everything? Do you have any learning features on your new standalone or did you turn off correcting?

Running a 034 Motorsport IIc stand alone and tuned by the shop owner Javad on a dyno. The stock ecu isn't being used at all to run the engine, I can drive the car with the stock ecu removed. What type of corrections or learning?


When do you hear compressor surge, during the launch, moving at wot or during the shift?

[Clay @ Kinetic]

FYI: Anti Lag essentially retards the timing so much that your exhaust manifold becomes a combustion chamber, there are explosions in the exhasut manifold and those are what keep the turbo spooled when you are stopped. Thats why you hear the huge backfires, they are retarding timing and having explosions in the manifold, Antilag is very hard on turbos and manifolds.

If you think doing K04 turbo swaps is a pain, imagine doing that regularly, and you would have to if you ran with an anti lag system regularly. Furthermore that would not be covered by any turbocharager manufacturer under any warranty. Its great for drag racing on circuits where you're sponsored but when it is a car that you'd like to be semi reliable its not the best idea.

On the 1-2 shift, thats ok, lots of rally cars have crazy compressor surge. Nice run

Yeah that's when I heard it. Sweet though man! I meant the kind of learning/correcting where the ECU actually corrects the afr bassed on your driving. Usually you just set the closed/open look learning to 0%. My last question to you... how does the car drive with the standalone? Throttle response must obviously be a little different right? General feel of the car? Is it smooth?

[mike-2ptzero]

It might not be compressor surge on the 1-2 shift, might just be me hitting the 8k rev limiter at the top of 1st(pulls back 40degs of timing) and plus I run a BOV and a dump on the exhaust at the dp. But the GT35r tends to have compressor surge on small engines when running over 20psi and I run 32psi.


My car was tuned 100% without using a wide band connected to the stand alone so no learning program was used. Car runs great with the stand alone, even drove it a few times back and forth to Norcal from Socal (8hrs each way) on the 91 program.

standalone... i don't need no stinkin standalone! but do wish i had one... does anyone have any info on how much to retard the timing comparable to boost and whatnot? or a linkup to a more informative site..?

Wait... they didn't tune your air to fuel ratio? LOL? Or you mean, you don't use one now..

I run a wide band on my car at all times, but what I meant was that the wide band has never been directly connected to the stand alone unit. The person that tuned the car set all of the maps on their own and adjusted all of it while tunning the car on the dyno to get the AFR perfect and get the most out if the car at the time.
