Anti-Lag Two-step

So I've been having trouble getting anti-lag while on my 6000rpm two-step. I've gone through all three high octane timing maps and retarded ignition to -15 from 80-140% load and from 5500-6500 rpm. All I'm getting is slightly more boost (about 11-12psi up from 9psi) and it still sounds, acts, and looks like a two-step.

I'm just looking for anti-lag on the two-step and launch and not a rolling ALS...

I have EvoScan and the works so if there's anything I need to change, I can if I'm told how since I'm still fairly new to EcuFlash. I've done search after search and I can't find anything really. What am I doing wrong?

Thanks in advance

you don't have antilag, that is all.

To have actual OEM mitsu anti-lag, you need some hardware that USDM EVOs dont have.

There is a thread about implementing it. Search.

I kind of expected you guys to figure you knew what I was talking about. Obviously there's no such thing as true ALS on the Evos without the hardware and/or another EMS.

I'm talking about ghetto anti-lag by retarding timing in the maps. Anybody have any info on this?

OP probably thinks the evo 2 step is like dsmlink, but its not and wont ever be. DSMLINK does have a real 2 step antilag where it retards the timing to the point your spinning your turbo with flames but its also gonna destroy your turbos shaft.

stop calling it anti lag, it is called a 2-step or stationary rev limiter.

There are a few ways to alter boost during the 2 step. alter rev limit (which you did), change timing in 2 step load areas (which you did) and last alter the rpm drop which the ct9a does not currently have control of.

I'm going to call it anti-lag because that's what it is, albeit a ghetto version of it...

And then you're telling me that what I'm attempting to do is not possible although I have a friend building close to 20psi with what I'm trying to get.

I know that I changed the rev limit, I know that I changed timing in my maps. I know what I have and haven't done and my question still isn't being answered really so I'll say it again.

I've retarded timing -15 degrees from 80-140% load and 5500-6500rpm and my stationary is at 6000rpm. Why is it not building the boost that I'm going for? There should be loud popping and occasional flames and it still sounds like a regular two-step but that's not why I'm getting it.

So can anybody that has knowledge on this topic please chime in?

Bring a bit more fuel in in those same cells. This is fairly destructive (like a real ALS) but effective for the desired effect.

Well I tried bringing it down to about 10.8 all the way around in the selected cells but it still wasn't doing much. Is that not enough fuel or is there some other underlying problem?

I pulled -15 degrees timing...now I know the stock ECU only reads -10 so will it read -15 as -10 or does it not read it as a valid cell? In other words, should I raise it back up to -10?

Thanks!

You need to add a lot more fuel when you are retarding timing that much.

How much would you say is a good amount? And do I simply add fuel through the maps or is there another way to do it?

Sorry, I'm kinda new to EcuFlash...not tuning itself but the program.

I think the better question is why do you want to do this?

Because effectively what you're going to do is break your car.

Your probably past 140 load once you start building any boost. You could try to adjust the cells from like 140 - 200. To the others in the thread, anyone actually have any solid info of proof of this damaging a turbo? Im not saying I do not think it does, just that when I asked for proof noone had much, but people love to say how bad it is.
