So i did play with the aar over the weekend . i took it apart and made some adjustments i was able to get a crisp 1250prm cold start no hesitation Then a slow 4-5 min drop to the 950rpm.
i was very please with the outcome . . I did notice the extended idle when i shut the car down for even a minute. it took 2+ minutes to regulate back to 950 just like everyone mentioned .. when i clamped off the hose to the aar it immediately held a perfect 950 after the minute shut down. while bench testing the aar i did notice the last 1/4 of the closing took the most amount of time and quickly started reopened seconds after the aar was deenergized.

. .. i have read about the cable activated systems some people use to close off the aar a great idea . i would rather use an electronic valve .. can anyone recommend a 12v 5/8" actuated valve .( thinking possibly a modern heater core valve )
On an interesting note. when i started the car to leave for work 1200rms. i quickly walked around to the back and clamped off the aar hose the rpms dropped instantly to 950 And ran like a dream . So far from what im gathering, i only need about about 30 seconds of extra air through the aar.
im contemplating adding a timed rib relay set to 30 seconds+- to energize a valve to shut down the air to the aar to automatically and close off the air 30 seconds after start. . wiring should be simple, i can incorporate everything directly off the aar.

one other advantage to the 1200 rpm start is I don't need to blip the throttle to shut off the red generator light.

update i found a Audi transmission solenoid cooling valve and a delay off solid state adjustable timer they looks to check all the boxes . i will update one i have everything installed.
