AntiLag: My expirance, whats yours?

Post by **calvin** » Fri Feb 29, 2008 9:55 am

meaing? or boostcut inactive when anti-lag active?

Well; I have noticed if antilag is left on, and boost-cut gets activated, you will get the most rediculous backfire once the ign resumes;

ok, I did some Antilag testing last night; still getting one good pop, then the spool up (hissing sound) then @ full boost, it starts poping again like there is no tomorrow; exactly what I am trying to get it do; but I want it to happen through the whole spool-up not just the end and beginning. I will do more tests... but i think the new FTL resume feature should be exactly what will make it work proper =)

User input required: Is your boostcut to low and that's why it activates?

FTL resume is disabled i believe in the 54 rom Resume is same as cut(minimal rpm resume).. I can enable it as test for you again.

actually; I never saw it enabled inmy version; Just greyed out... so I guess I was missing something =P

I started playing around with this tonight. I get huge pops and back fires (with flame) throughout spool up and boost. I only get about 6psi of boost though. The most aggressive settings I have tried are 6500rpm 50rpm resume 35* retard and 75.00 to fuel. I can try adding more retard to see if I get any more boost but it got late and it was annoying the neighbors. I am not looking for flame or sound but just the best functionality. Its certainly not as smooth (as in rapid bang bang bang bang) as an msd system or the video posted earlier here but it does work and it does build boost. If I could get up to 12psi that would be great. I'll keep playing and post my findings.

keep the fuel between 30 and 65... you will get nice results... I am building 10PSI pretty quick.

The FTL resume needs to be higher the higher the RPM's go; so if lower RPM lets say 2K, your going to want a 5-25RPM resume; 4,000: 75-200RPM (didn't go higher) Heres something interesting: When I would get it dialed in to emit a huge pop down low, you would get one good pop, and a bunch of smaller ones when the fuel/ign was optimal for that RPM. But at higher RPM (4K) with a 108RPM resume, I get one HUGE pop, and it will pop small, or rev waaaay smoother and make more of a hissing sound; this could be 2 things in my opinion... too much retard, fuel or more FTL resume added.... need to expirament more. *** I think to control the 2-step better, there should be a slope for fuel Vs. RPM, this would give a better result IMHO. Maybe low and high RPM values (user definable) and low and high fuel values. So, end result for me tonight: I think the one HUGE pop will be waaaaay more than enough to get her up to 14+PSI; but I do not have a turbo on right now, so I am just using my "Soon to be vitara'd motor" as a guinea pig. Good news: I took video, deafened my friend, felt a huge compression wave each huge pop (flamage) and it kinda blew a shitload of crap everywhere, and killed a bunch of a small plant I was parked in front of; sent plant into the parking lot =P Problem: I have no way right now to download the video off the FireWire, cause this laptop doesn't have it... and my home PC's power supply fried. Soon... I promise... like 1.5Ft flames! (with OEM header, catalytic converter, and Anyways, here's the eCtune settings pics, and as soon as I can get a machine with 1394 to download the video, it's all goin out to you guys =) It turns some heads!!!

After making a base tune, I tried your anti-lag settings toninght, I was building 4-5 PSI boost and shot a nice big flame

Nice feature! I will do some more testing. Now we have to find a way to use anti-lag during shifting/off throttle

I always make lots of boost on antilag.. Don't understand why yall are making such low amounts of boost..

Well, 1: My wastegate is set to 6 PSI, enough for me, I'm not a drag racer. Car is a daily drive. 2: I noticed afterwards that I had fuel cut enabled, I will try again with ignition cut...

ahh, I thought you were having problems building boost, missunderstanding..

No no, My post was to share a positive experience

crx303 · Post by **crx303** » Sun Apr 06, 2008 4:25 pm

OK, just did some more testing. Changed fuel cut into ignition cut for the rev limiters and wow, I got the loudest pops with flames. Then disabled anti-lag and tried only FTL with ignition cut. But also very loud pops with flames (luckily I was in an industrial area). FTL with fuel cut, normal rpm bouncing FTL with fuel cut and ignition cut, normal rpm bouncing I think I can understand why I get these explosions, unburned fuel passes through the engine, comes into the hot exhaust manifold and explodes. But anybody with the same experience? One more question: Why is the \"set resume rpm\" in the FTL settings greyed out in both TPS based and memory based?

The greyed options are something I was requesting, because at different RPM's you get different results; this would allow me to seperate them somewhat to get more of a feel on whats happening between each change. As for an update: The boostcut was being hit because my WG diafragm was ripping.. Slowly making its way to 10.95PSI where it is currently holding. But my main concern for the antilag being disabled during boostcut is if you hit boostcut before the engine has warmed up (as my buddys do when the car is cold) it will backfire something fierce.... unfortunately for me; I mushroomed out a muffler accidentally hitting boostcut on too many times. Good news is; I have not hit one of those rediculous backfires yet; but I am running +0 fuel on AntiLag presently... (need to sit and do another test in the woods again. I have noticed if you play with the FTL RPM, and slightly vary the ignition/fuel values, you can get past the 6PSI mark... I was able to build 7PSI @ 5500RPM
