Before you read on there is no specific VR4 info here, but there is a lot of Mitsi stuff. Apologies if it has already been posted.

I found it while trying to find a 4WD ABS tech manual, and this site has the full EVO 6 manual, which I assume is better than nothing

Also, if anyone could tell me what other (if any) Mitsi vehicles have a similar ASC system, that would be greatly appreciated
