A couple thoughts cross my mind:
1) Might be possible to use the ISCV for air bypass into the intake manifold. Not sure if it opens and closes fast enough though.
2) The brake booster vacuum line could provide a source of bypass air injection into the intake manifold. Might make the brakes somewhat ineffective though. Are there any other big inputs on the intake manifold?
3) I do like the idea of an exhaust manifold air injection system. The GTSpec exhaust manifold has the factory SAS fittings on them, and they do feed into the exhaust pipes, so that's an option.
What solenoid to use to feed #2 and #3? Seems like a fairly high flow valve is needed. A solenoid-controlled diverter valve sounds cool, but it would need vacuum, and isn't the IM under boost during antilag?

1 & 2 on my car, 1 & 3 on EvoRS. No need for a vacuum canister.
There is a very specific reason I am not disclosing anymore than we did in the disassembly thread. Everyone that has tested it with 2 exceptions (one drag racer and one road racer) have had me take it off. If I was to gamble a second reason it would be that after I taught the ricers to advance the intake cam at idle to get more aggressive sound out of them I have regretted it non stop. My Karma cannot survive a second punishing as it already has.
The easy version (#1 only) is great for road/drag racing as it does help the shifts sync far faster. There is of course more to it than just using the IAC but thats a big part of it. Here is an example of our setup which utilises #1 in part-

Have ausdm 88580714 with proper als def. Need to compare pinout to see what might need to be changed Vs usdm 88590715. I hope not very much. The aem patch harness seems like a good way to achieve reversibility, and repinning. Any thoughts ? I don't know squat about hex or assembly. I'm keeping in mind reversibility because I have US emissions to comply with once a year.

Ok still going with the get hardware functional, and travel from there.. The adm rom has a few quirks imho but I'm sure that its perfect for the job.. still searching for appropriate hardware stuff.
If the adm can retain my omni 4bar and wbo2 ecu logging I'd be tickled. I should think so via adc.

I have my UEGO wired into my USDM rear o2 pin now, so that should simplify atleast a basic function.. Is making an ECU report a signal to a specific pin as simple as changing the output location in the instructions? is say moving pin 4->59 in a rom difficult? leading to the solution of just retaining USDM pinouts ADM rom?
I am still counting on a patch harness that would PNP the rom though. How do I actually figure out what outputs do on the ADM rom?
