You have an '03 or '04, right? If you just put in the new center diff and didn't change anything else, then you still have the stock Viscous Coupling Unit (inside the transfer case). If you took the VCU off and bolted on this new part, then you are using what Greg calls a "spool", which sounds like it makes it a completely open center diff with 60% rear bias. The car handles very differently with or without the VCU. . .

Unless nils cracked open the TC he is still running the OEM VCU. That is the config GSC is recommending.

Nice to see a review of this. Curious how it will be in an autox type of situation.

Actualy AYC cant operate a a standalone. it will need adjustments to cut it apart from the connector on the ACD on the 8 and the 9.

intersting discussion so far...now that we back on track - the novises!

you are unfortunately incorrect my friend. while in the newer evos AYC and ACD are definately interactive, it can operate as a standalone unit. just as it does on evo 4-6's. in the newer evos, it does use some of the same imputs as ACD (whioch is what you are refering to, the imputs run through the same harness), but both ACD and AYC operate on seperate computer systems. case and point, the AYC system from a 7/8/9 can be bolted into a 4/5/6.

as for being more on-topic, it seems as though the GSC unit is still an LSD using the stock VCU, but still runs the higher rear split? thats what i would be looking for if i were to upgrade
