Honestly, I don't know enough about ACD to know what kind of benefit we're talking about here. But I vote yes just because I'd like to see what kind of gains you could get out of it...

I have found no evidence of someone trying to equip a USDM Evo with an aftermarket ECU however.

the information came from a thread that Terry S made, as to where he got the information im not 100% sure. I dont know the exact inner workings of how the ecu's interact, i was just going by what I read in the thread. If David or someone else would be so kind as to enlighten us as to more specific specs in regards to the ACD and ayc ecu so that we could get a solid answer that would be great.

back to evo 101 for 2006 models
JDM evo rs no ayc = USDM rs
JDM evo gt no ayc = USDM GSR
JDM evo gsr with ayc = non USDM evo
JDM evo mr with ayc = non USDM evo
USDM evo mr = JDM gt + 6 speed gear box and some accessories (vortex generator)
so, ralliart ACD ecu is design for JDM rs and gt, then it will work with the USDM evo.

We know there are advantages to tuning it because the Non US race cars don't use the stock programing. The suggestion that the JDM ACD re-tunes won't work on the US (non AYC) spec cars makes this all-the-more needed...

Interested. I would also like to suggest using the stock ACD switch to change between custom presets. You could illuminate combinations of two LEDs to indicate the different presets (I believe three LEDs on simultaneously are reserved for the fault state). This would give an additional three preset indicators.
I would be even more interested in an S-AYC-like product. Given a car with ABS and a yaw sensor, it should be possible to add some servos and some control logic to add the functionality. Of course, a steering angle sensor may also need to be added.

ACD does not split power.

Please get your fact straight before you post.

acd tuning huh? what is the max torque taht can be sent to the back? Is it possible to get up top 90%? How fun would that be. Paul... we could try a formula d stint at that point.
