Evo anti-lag ECU disassembly
i am making a system when i get home, which will be in about 5 weeks, so as soon as i make it i will be posting a how-to on how to make it. if the controls for the air valve can be put into USDM ecus, that would be awsome but if not no big deal, it can be controlled by a simple 555 timer.

hey jcs, do you know if the pin out for the JDM IX ecu is the same as the USDM? because if it is or if the pins are just unused on the USDM then i could get my hands on the air valve selinoid that sits on the manifold, then i could controll the switch via ecu. Or if we could find a cheaper selinoid then we could mimic the ATLS for USDM evos. i mean cause other then that switch the rest of the system is rediculiously simple.
so there should be some pins that are unused correct? if we could put the routines in, basically like the mods tephra and others have been making then all we need is pins for the out put to the switch. From what i saw there should only be an out put from the ECU. i don't know man you guys are way smarter at this ECU dis. stuff, all i do is tune them. you let me know what you think.

Ok guys.
I have just changed the spec of my car.
I previously had removed the sas due to fitting a stainless manifold.
However when I changed the turbo, I fired the car up for the first time, and about 20 seconds later the manifold cracked
So I went back to the stock manifold, and refitted the sas.
I also drilled out the hole in the 2 banjo bolts to 5.5mm (tip I was given a while ago from a friend that used to rally evo's).
Anyway now I get the normal pops and bangs from the timing being retarded in the low scales, however on gear shift, from high RPM I get a loud bang and a flame
I have added some numbers into the ALS Air injection time, which have given it the flames on gear shift.
I am just wondering, if I add higher numbers (more air ??) will this increase the noise and flames ?
Or would making the numbers lower (reduce the amount of air) make it more violent ?
I am unsure if it needs alot of air to be injected to get it going nicely, or just a small amount to get it started off ??
