tinkering with fresh air or egr type anti lag systems

heres a whole bunch of my progress. Started by acquiring my OEM hardare from a gentleman who had access. The I saw some room for improvement, trying to utilize the stock ECU the whole time. A couple revisons + the stock set up and I realized that the manifold has pencil lead sized holes in it. Not ideal. So the I started acquiring some parts to make the system a little higher flow and relieve some of the compressor back pressure that seemed to cause surge IE the small manifold holes. Now Im using a -20 hose set up with a MV 38. I had a fitting turned to fit the outlet( now my inlet). Soon I will have a vi-pec in my hands to do more legitimate testing with. Ill keep updates progress here, instead of the ECU FLASH thread which is cluttered with progress of some of the mechanical bits rather than ECU development. Stay tuned.

Interesting setup, a bit too much going on in the engine bay for me though. So why are you putting this setup together, for autox or what?

This comes standard on evo 5's and 6', I spoke with SpeedTech Motorsport (builders of the RWD Evo drag car) and they said on stock ECU it's not enabled and some its not even included so I doubt it's usefull in its stock form. Technically it's the RaliArt Anti Lag System.

Awesome work so far. At this point wouldn't it be better to design a custom exhaust manifold for the anti-lag system?

I can see that being an evolution perhaps. A side goal is maybe to achieve success here and allow others the opportunity to benefit.

From the things I have heard, not first hand experience this is a little easier on the motor. While also retaining vacuum so it could be a very viable option for the right users. No one knows enough at a consumer level to even know precisely what it takes.

In the ecuflash forum there's a 750 plus post of information and general conversation documenting wealth of knowledge from many resources . If I can figure out what it takes on a stand alone to achieve results maybe, we can have some tweaks to the stock ecu making it even more consumer friendly . I don't know how much ign retard or cut or fuel is actually needed ... No one that I have come across has laid that type of info out there.

Its hell on the manifold and turbo though.
See if you can get a flash of a Evo 5 or 6 ecu to see what is there but not turned on for the anti-lag

Nothing personal jush, the op in ecuflash has a ton of information and progress probably worth a glance.

most of little interest to the majority of evo owners.

worked, ran, improved and tested some more, and sold my evo. There's a continuation of this on a 2.4l gtx3582 gen 2 1.01 twinscroll. The set up is geared around a 500(with generous headroom)+ easy and reliable 93oct build with exceptional response. But that's about 6+ months from seeing oil pressure.
