Not sure if this is any help for the earlier DCCD system? I was watching one of several Japanese WRX/Evo DVD’s I’ve bought recently and one of them is more or less a history of the Impreza from 1994 to 2002. I think it was for the 1996 car there was this DCCD explanation with a demo of the effects on a slalom course. I took this screen shot which shows nicely the torque split.

 

the effects on the slalom course part sounds intersting

 

can someone host a clip perhaps? i wanna see this...

 

Unfortunately I don’t have the technology to grab a clip off the DVD, or I’d be happy to do it. The slalom demo appeared to be running free, which resulted in lots of over steer, against pushing more power to the front which resulted in a faster time. I think the guy actually went round a tight course fully locked at one point. Not speaking Japanese makes it a bit hard to take it all in

 

What was the name of the DVD?

 

Lancer Evolution vs. Impreza WRX. Best Motoring volume 4.

HERE or you can go HERE and do a search for "Best Motoring" or "WRX" or "Subaru" to get a whole heap more. Think I might have bought the lot now

(PS Most are region 2 NTSC and Japanese language)
