How to Setup Real Antilag for $10!!

- In this video, I show you how to set up a real anti-lag system on a Subaru and possibly other cars. This can be done for cheap, all you need is a switch, or button, and a relay. You also need some way to modify ECU tables like ecuflash, romraider, or cobb.
Here is the link to the forum post where I got the idea:

The iat temp comp pulls timing from the main base timing table so calculate your lc timing off that number also set your lc timing cut hesterises to 25 rpm swing like 4400 max and 4375 so it doesn’t bounce as much. Helps a ton
I'm trying to understand what is going on here. Are you flat foot shifting and it keeps the boost up or does the boost stay up no matter where the pedal is at? Is it basically creating engine resistance via ignition at a strange moment?
It doesn't really matter where the pedal is. The way it works is it retards the timing so much that when you floor it the car doesn't accelerate because the timing is so retarded but it still generates engine load which causes the turbo to spool up. So when you let go of the button and the timing goes back to normal it accelerates with full boost. Hope that answers your question
This just a Subi thing or is it a can be pretty universal thing
I'm sure it can be done on other vehicles, the limiting factor is weather or not it has a tuning table that varies ignition timing based on intake air temp. If you can find that table and edit it there is a pretty good chance it will work
@@SWSpeedCo you have a build break down on all the components to make this correct? 😂 I totally need to make this for my jeeps new forged setup
Yeah, all you need is a 5 pin really, a switch of your choosing, and some wire. Most importantly though is being able to tune the ecu like I said earlier otherwise it won't work
@@SWSpeedCo gotcha Ile be doing that via hptuner
What was black box with all the red wires in it ...sorry I'm just intrigued by this and always wanted to hear a boosted 4.0 with antilag 😂
thats amazing dude keep it up
Thank you
My relay the opposit haha as in switches from the middle pin to the outer but it’s still labeled 87a and 87b
Disable the iat temp low input or high input code and it goes away
Sheesh need this done to my cae
that is launch control not antilag, that being said... i will be using this trick as it is a good one
the are different things, anti lag keeps the turbo spooled between shifts
Yeah its not exactly a rally style antilag but it is a ignition cut rather than a fuel cut 2 step system, idk what the correct terminology for it is, but its pretty cool
@@SWSpeedCo defiantly a cool trick, keep the content coming man I love the subi tech!
Have you run into any issues with this ALS? does it damage your turbo and put a lot of load on the engine block? I want to do this, and planning on showing my tuner.
It's not the safest thing. I wouldn't recommend doing it with a stock turbo. I've heard the ball bearing turbos are better for handling this sort of thing. I haven't had any issues with it yet.
On the relay where did you wire 87 to? pin 30-iat to sensor,
pin 87a iat to ecu, power, ground, pin 87?
Pin 87 doesn't connect to anything, you are just using it as a point of disconnect if that makes sense. Normally with 5 pin relays your devise runs through 87 and 30 so when there is no power the circuit is opened and your devise is off. Then when you flip the switch it switches from 87a to 87 and closes the circuit and turns your device on. In this setup 87a doesn't connect to anything. What I did here is the same but flipped since we want the circuit to be closed all the time when no power is applied to the relay we use 87a. Then when we apply power it opens the circuit and makes the ecu think the iat is -40 since it is no longer connected to the sensor
@SWSpeedCo Wow. You're on point. I could not have asked for a better explanation. Just rebuilt my project ej25 and doing my final inspections before I drive it. Then I'm going do this install. You have earned a follower, my friend!
@masubi5784 Thank you, glad I could help!
@SWSpeedCo Bro. I am running just about the same setup as you to include eflexfuel kit and am having issues with stumbling. Is there anyway you could help. In your install video of eflexfuel you spoke about inj. timing. I am out of Texas.
Can you describe the stumbling in a little more detail and I can try to help
Hey dude, nice video. I've been trying to replicate this but in an Evo ROM but i don't see that compensation table. Any idea or experience with that rom?
I dont have any experience with Evo roms. It might have the table but it may just be under a different name so I would either check the forums or look through all the tables and see if there is a table containing timing and intake air temp.
@@SWSpeedCo yeah, there's a table named similar, but it does trim timing compensation, but it does it on percentage, so harder to figure it out
Yeah that does make it harder, might require some trial amd error if no one has done it yet
Where i live it gets to that actual temperature. Is that an issue? If my map senses the cold temp and puts the car into anti lag lol
Where do you live that it gets -40 degrees? Yeah I don't think you would be able to drive your car with this setup if it was that cold out

Looking good. Cool that you are tuning yourself.
how do you activate two step? is it rom like that? I own JDM bl5 and it doesn't have this feature :( also couldn't find 32 bit speed density rom
If you look on the rom raider forums there are some writeups on merp mod patches for the ecu. Its basically a update you can apply to your ecu if your car Is supported which gives you 2 step, flat foot shifting and a bunch of other features
@@SWSpeedCo yes, I have read it, but as I understood it is for US cars with 2 AVCS. Mine have 4 ones and ecu is different number. Have you ever heard about posibility of upgrading JDM rom?
Another possibility for you would be to get a wot box
You just need to go standalone.
What is the program do you used?
I use ecu flash for tuning and romraider for logging
@@SWSpeedCo how did u download romraider I have a problem keep saying 32 bit also can you read everything on the ecu with ecu flash like how much boost afrs etc
You have to download an older version of Java I think, there is a pretty good walk through on the forums. Ecu flash allows you to read and modify everything, there are well over 100 tables
@@SWSpeedCo do you have instagram or something I can message you I got some questions brother
Yeah, it's the same name as my TH-cam channel
can you not install merp mod for the 32bit ecu?
You should be able too, my car is a 32 bit ecu, it just depends if there is a merp mod for your specific car
What software are you using
Romraider and ecuflash
Is this for diesels too?
I dont know too much about diesel engines but as long as the ecu has a iat timing compensation table you should be able to do it
is this what a wotbox does?
It's a similar idea
What do you tune with
I use romraider for logging and ecuflash fore editing and flashing
not antilag. this is another 2step
It isn't exactly antilag, but it isn't 2 step either. 2 step is quite literally a 2nd rev limiter. It functions the same as a rev limiter by cutting fuel at a specified rpm. What this does is retards the timing to allow the turbo to spool up which just 2 step won't do. Hope that explains it better, thanks for watching.
That car looks like a lot of fun!
Yeah when it's running lol, I can take you for a ride sometime when your back in town
How much would it cost to build a whole kit and ship to 96706
