Evo anti-lag ECU disassembly

I'm wondering if the leaning and advancing that goes on is a lean burn setup to try to save fuel? It would make sense that it needs to go back to stoich occasionally to see where stoich is?

Here is my question? Will this work only with the stock turbo or could this work with aftermarket turbos, both stock location turbos and rotated mount turbos.

Anti-lag should work with anything that can go onto the stock exhaust manifold that has the SAS ports and a turbo that won't melt
The settings I used to test this are very subtle and just give a few rumbles in the exhaust on lift off, not sure it really makes a huge difference to lag. I'm not running it any more beyond a simple test.

Is there a chance that several of the "antilag" tables (BE Enrich/Enlean, and adv/ret) actually do something else like emmissions or like you said, milageand perhaps need a title revision?
Which maps are intended to assist true antilag fitted evos and which ones just assist boost (or try to ) for USDM ?

I think the only stuff related to anti-lag is the stuff I showed in my image on page 1 directly related to the SAS valve.
I think all the lean spool/BE/adv/ret stuff is economy/emissions.

I disabled Lean spool by changing 2 to 4 on the stop and made RPM same as start.
Do ya'll think the funky antilag timing and fuel maps kick in when EGR responds to NOx's? I guess I can partly confirm by riching the fuel maps to 14.7 and seeing if I still get those 15.7 AFRs @ 60% load/2000-3000rpm since I have no cat and the rear O2 is dummied
