Surfing Japanese Evo mod sites tonight and came upon this: (Scroll down)

For around $500US that would kick *** if thats all there was to it. Does anyone have any experience with this?

 

i have heard of the more agressive ACD ecu you can buy. It basically has more aggressive lock up rates for the center diff.

I did inquire about this before and was told that it was ment for comp use only on extremem surfaces (read rally use), the reason being the ACD being that non servicable unit that it is would reach the end of its life (read fail) much faster with it.

Unless you going on some serious gravel courses of snow tracks, and plan on replacing your ACD unit regularyly not recommended.

PS I think you need to have an ACD unit already installed to use this.... i think its just an ECU swap (the ACD ECU is independednt of the engine ECU)

 

This is only the ECU it self, I have it in my VII but of course you need to have the complete ACD system to start with. Sorry, but no complete ACD for US$500
