Its working, its just the expectations of what it can do need to be adjusted in my case, if theres no grip to be had on the road then the diff is not going to chnage that, you'll just get two wheels slipping instead of one. The roads are perilous around my way, its not city driving, its a mixture of A nd B roads out in the country side that are in wide open space and so prone to frosting/icing as well as being covered by mud etc. from tractors.
Another 2 cars fell victim on my journey this morning, again on the slower roads, head on after a tight bend, my guess the ZX took it at 30/40mph which is reasoneable to do so (70+ in my case normally
) but had to deal with frost/ice understeered onto the other side of the road taking out a Clio, nice. What annoys me is that this will add to the statistics for speed cameras but nothing will be done to teach drivers how to deal with and assess road conditions
Long and the short of it, the diff does its job, with the ASR off on cold damp roads I can floor it and have grip to move (providing traction is there to be had) , very minor wheelspin, I can be fairly aggresive in a corner with the throttle and I don't get wild understeer, the odd side to side shake at the front where the car is going from grip to no grip with wheels trying to catch and teh car cuts in.
I think a few people will like myself expect this thing to suddenly make it so your front wheels will never slip again, thats not the case you have to drive to the point of slip and thats when the diff starts doing its work when theres a differential between the power transmitted to each side. I also thought it would work with ASR on and to a point it does but the action is much more pronounced with it off which when you think about what it needs to work,which is wheelspin it starts to make sense. Most of my issues have come from expectation and not knowing what to expect, the car is different now an I need to learn how to drive it.
My only other experience of diffs where on an Evo where the action is a lot more aggressive and you can really feel the torque shift, the Q2 is very refined.
