Ok awesome is there a thread with info? I would prefer it to eliminate the ayc so I don't have to sit there everytime before I race and hold Down The button. I will /would love to test a prototype asap !!!!! I was considering trying to use a ralliart Tarmac acd computer if it would work and just eliminate the ayc without any side effects but this is way better

No, that would be center diff (ACD) lockup and that would burn up the center diff in a hurry.
The ability to modify the rear diff lockup (since it's electronically controlled) would change how much power it takes to lock the two rear axles together. This is something you can manually tweak with a clutch-type LSD by adjusting the tension on the clutch packs. Ours is electronic, so you have to reprogram the AYC computer in order to change it.

no the acd mod will push more pressure and do it quicker to the center diff pushing more or less power to the rear of the car ( i always shut off the AYC which helps maintain vehicle stability by putting power one way or the other in the rear end)

I think the throttle cut is pretty obnoxious unless you are on a snow covered road so I usually always turn off my ASC button on the dash with one press so that the ABS still kicks in to assist with where the car is trying to steer.
For most drivers I wouldn't think disabling the AYC functionality would be a positive move, but I can see where changing how quickly the ACD locks up the rear with a wider range of change would be beneficial. Right now all 3 settings are only a slight difference in driver feel at the limits. You wouldn't think tweaking those times in the ECU would be that difficult but who knows.

yeah if they can quickin and better the hydrolic line pressure to make the rear lockup quicker that would be awesome and obviously they retune the settings for more rear bias and such. i may end up having to do a mechanical change to a cusco rear 1.5 way or something if i can't get something soon with a reflash or ralliart reflashed acd computer
