My DSC Sport V3 controller arrived yesterday. My aim is to improve the ride comfort on our local rough roads without adversely impacting handling. Unless you fit new electronically-controlled dampers, the controller works only with cars fitted with PASM.
The pre-programmed maps clearly giving better ride comfort and the depth of software control is downright impressive. Right now, the box looks incredibly cheap.
I spent about an hour doing some tuning of the maps this morning. All my tuning was of what they call 'comfort mode' i.e. when there is little longitudinal or lateral accelerations. Here are the tuning changes I made:
- increased the default damping rate (out of the box it was a little low, allowing some wallowing)
- reduced the accelerations needed to switch to the performance map (so even relatively gentle cornering / acceleration / braking switches to firmer damping)
- reduced the high shaft speed compression (so taking the edge off sharp bumps)
- increased the low shaft speed rebound (so more firmly damping waves)
- increased the damping that correlates with speed (so compensating at high speeds for the softening done overall)
I'll do some more tuning later today, but I'd say it's about 80 percent there.
Interestingly, softening the damping makes the steering less responsive, as the chassis doesn't react as quickly. So steering corrections in a straight line now need more wheel movement.
I haven't done any tuning on the Sport switch position mapping yet, although a quick try of it shows that the pre-programmed mapping is much more suitable for my roads than the Porsche standard mapping.
