Evo anti-lag ECU disassembly
If anyone would like me to source the ALS hardware (SAS system) for their USDM 8 or 9, then let me know.
I'm in the UK and it should be fairly easy to locate as a lot of people remove it to run aftermarket manifolds.
It won't be worth me sourcing a manifold with the ports pre-drilled, as they weigh about 11 lbs and will cost a fortune to ship. I understand that you can drill the standard USDM manifold to fit the SAS hardware though.

Cool, I'll have a word with my mechanic. He only works on Evos and his workshop is an Aladdin's cave of used Evo parts. I'd be amazed if he hasn't got an old SAS knocking about.

Using the evo9 locations given by the OP I have found the locations for the JDM evo 8 and evo8MR ALS maps. PM me if you want them.
That is ID's 93660005 and 96260007.

standalone ECUs use the software to retard ignition timing(-10 to -15*) and add 10-15% fuel on liftoff....of course, this is user editable.
The factory Mitsubishi Evolution uses actual hardware that is connected to the exhaust manifold, which includes a air pump. This is the "hardware" we reffer to when we speak of the factory anti-lag system.
If you look close, you can see the lines that run just under the valve cover along the head.....they bolt down into the exhaust manifold.

Ok good thread however there is some misinformation.
There is NO air pump the antilag plumbing draws it's air from the intercooler pipe just before the throttle body.
The control valve (which you can't see in that picture because it's taken from the wrong angle) is controlled by an on/off solenoid. This on/off solenoid controls a vaccum line from a small vaccum accumulator (connected to the inlet manifold) to the control valve diaphram.
There is also a reverse flow check valve which stops pressure from the exhaust manifold going back into the intake.
The large banjo bolts on the exhaust manifold end of the pipes have very small holes in them. This is a production car issue where the system is not being used as intended (or used at all!). The plumbing is clearly sized to flow a reasonable amount of air, certainly more than the tiny holes in the banjo bolts.
Remember with the GroupN and GroupA homologation (EVO5-6 WRC rally) if you wanted to use anti lag on the rally car the anti lag system had to be on the road car. It didn't matter if it was not enabled so long as the hardware was on the road car. This was the rules.
The ignition, fuel and actuation stratergy to make all this work I have not investigated however I am sure for it to work the bolts at least need to be drilled out.
I am using an EVO7 ECU if somebody finds the anti lag tables in the EVO7 JDM ROM let me know
If you look at my signature you can see I own a EVO6 TME so this info is first hand from my own car.
Hope this helps.

Interesting. Are we close to getting this to work? Or at least emulating the stock ECU to use a system that is similar to how a standalone does it? I want to put all my thermal coated exhaust components to good use

Just a note - if you make it work similar to a GrpN ALS - then you have also to adjust your brakes system (your brake booster will not work anymore as there will be no vacuum available to make the booster work) - of course assuming that you run your ALS with positive boost all the time.
So what I have seen on cars with Autronic or Motec with ALS - they still are slightly on the vacuum side - in order to keep the brakes working properly when the throttle is released.
For drag racing this is not an issue of course - there you can have ALS with 1.5 bar at startup - I am talking about twisted road driving where braking is important

1) ALS minimum time to trigger (default: 12s)
2) ALS Delay delay before air injection (default 2s)
3) ALS Delay delay before fuel injection (default 4s)
4) ALS Air injection time (default: XXX at all rpm)
I assume (1) is the amount of time you have to be over the all of the "ALS minimum X to trigger" parameters before ALS will become active?
How do (2) to (4) affect the ALS operation? Do these need to be adjusted at all, or are they set to produce pops and bangs as they are?
cool could ya find the ALS stuff in this rom please
also I found that there is a table that limits the ammount of timing retard you can have in the timing maps,
but I cannot find the actual map address,
if it could be found it would mean the stock ecu timing can be set to more than -10
which is needed for some serious pops and bangs lol.
