OK My turn...
I finally got round to fitting my DSC unit 2 weeks ago. Wiring in the 3 Axis sensor is a pain in the arse! There is so little room to pull on the correct wires, splice and solder the connections. At first I wired it wrong and connected the 12V to the wrong red/grey stripe wire (which triggered an airbag fault and also gave the wrong voltage :roll: ) I had Matt at Porschacare check the wiring and he connected it to the correct 12v feed.
We'll ignore the initial test drive with the 3 axis wired up wrong as this just puts the DSC unit in sport mode only and not very responsive, (at this point I thought I'd wasted my money as the car rode better before).
However with a properly wired sensor the DSC unit is OUTSTANDING :mrgreen: :mrgreen:
My car has Eibach springs, H&R rollbars, new Bilstein B4 damptronic front shocks (will fit these to the rear later as well) and GT3 front lower arms. I was already pretty happy with how the car drove with the original PASM unit, (Eibachs are progressive rated springs so the ride is actaully more compliant than the original linear springs.)
ROAD:
With the DSC unit fitted and in Normal mode it is a touch more compliant but has noticeable more control when pressing on our bumping country roads and especially when braking. :thumb:
Sport mode initially does not feel much firmer than Normal (but stiffens up much quicker) and the original 'Sport bounce' has gone. You can genuinely drive round in Sport all the time, (although I still prefer Normal even for fast driving on our bumpy roads as its so controlled.)
TRACK:
I went to a trackday at Bedford on Friday with the DSC fitted. I only used the SPORT setting on track. Initially it felt like there was still a touch more body roll initially on turn in than I'd prefer (although it always has felt like this in the past on track due to my 'progressive' Eibach springs), but then you can feel the car stiffen up and it just GRIPS!!! Braking was also SUPERB (I have yellow stuff pads and ATE fluid which never seems to fade), I could brake very late and hard and the car would just stay level allowing all 4 wheels maximum grip to slow me down. Matt from Porschacare was there and I gave him a passenger ride and he was blown away and just said it was EPIC.
Overall I am very impressed and VERY HAPPY with my current setup. I though long and hard about my suspension choice and for ages considered coilovers (Ohlins, B16 Damptronics etc), but my car is still a daily driver (with the odd Alpine road trip and 2 - 3 trackdays a year), and as good as Ohlins are they will still be noticeably stiffer on the road than I'd want day to day. Bilstein OEM B4 Damptronics, Eibach springs, H&R rollbars (set full soft at rear), and DSC PASM give me excellent ride comfort and control on road and still at the touch of a button great handling on track (for my skill levels anyway, don't actually want or feel the need to go any faster on track than the car can do now).
I've also spent sometime looking at the DSC tuning software and connected my unit to my PC to have a look. (Not made any changes yet). It does seem very easy to tweek the shock firmness ranges for Normal and Sport settings. Our PASM shocks have a range of 1500ma (Full Soft) to 400ma (Full Firm). The default settings on the DSC unit are the range of 1500ma - 500ma for Normal mode and 1200ma - 200ma in Sport mode, (this means the shocks are fully firm 400ma by about 80% cornering G setting in Sport). For my next trackday I may tweek my Sport table to start at 1000ma going down to 300ma, so they are a bit firmer initially, (although to be fair it handled amazing as it was). Like wise I may change my Normal setting to 1500ma - 400ma (ie use the full range maximum soft to maximum stiff), as it will just firm them up a touch more when I'm really pressing on
uh:
The DSC unit (and 3 axis sensor) on a 997.1 are excellent, you may not notice that much during normal driving, but when pressing-on on road or track it excels. (Just make sure the rest of your suspension is also in good condition to get the best out of it).
