Admittedly, the nomenclature we've been using to designate controller type and firmware version is a little confusing.
The V1 controller refers to the 9x7 Plug N Play unit. The V2 is the 9x1 controller featuring velocity tuning and dynamic motor mount control.
Whether or not it uses the 3-mode blink sequence or 2-mode factory-like "normal" and "sport" indicators depends on the firmware. Both 2-mode and 3-mode firmware are available. We encourage people to update to the 2-mode firmware, as it is a superior tuning strategy and that way everybody is on the same firmware.
However, for those that feel they are losing something by switching to two, instead of three, modes we will still offer the 3-mode version

Hey guys- Not sure if this was covered earlier in this thread... if so, sorry for repeating. My question is about AWD cars and DSC. Are there any differences in behavior or feel that occurs with installing DSC into a 4/4S? Does the DSC need to be tuned at all to not interfere with the AWD system? I am guessing the answer is "no." But I have no direct experience with the product.... 
Anyone have an install completed in real world on a AWD car?
Thanks!

So looks like I'm the latest to join the DSC train. Had the module installed yesterday by the nice people at Parr Motorsports in Crawley. I have to say - wow, what an extraordinary thing it is. The car feels absolutely glued to the road now, and even more so in sport mode (which is now comfortable enough to use all day).
The main difference I've noticed is on turn-in. I used to feel I had to trail brake to get the nose to bite how I wanted it to, but now it turns in on steady throttle like it's a mid-engined car, and still has the rear-engined grip coming out. A tiny bit of me had always found the handling of my old Boxster more intuitive than the GTS's, but not any more. Also, the steering seems to weight up better mid-corner and give more feedback.
There's a lot more feel in general, yet bumps seem to upset the car less. I should say that I have PDCC, so some of the improvement might be because the DSC system starts working before the PDCC bars would be felt. I like the comfort of PDCC, and the flat feel if I really chuck the car about, but I felt there was always something slightly unknowable about it - like I wasn't completely sure how much grip there was (but since this was always 'loads' it wasn't too much of a problem!). Now I fel I know exactly what's happening with all four contact patches.
Re this, the only slight negative I've noticed is some more vibration when going in a straight line. One can really feel the road surface, but maybe one doesn't always want to? Parr said they thought this was because of the dynamic engine mounts' having been stiffened, and that we could dial it back, but some of the tautness in bends might be lost. I'm going to live with it for a bit and see how it is.
Any more thoughts on this appreciated. My main thought is that everyone who's serious about going fast should look into this thing. Hard to believe Porsche left so much on the table suspension-wise. I guess maybe there are going to be little 'enhancements' done every year for a while without anyone having to do anything expensive like design a new shock. Nice to have the fast-foward option anyway!

Just upgraded mine, it went on a 2015 GTS without PDCC...
so just to make clear, there are 2 modes, "normal" and "sport", which is activated via the suspension/shock button on the central console?
what does the 3rd mode offer on the '3 mode' version?

Just had mine out for a spin. It now corners at over 1g with no tyre noise whatsoever, so more to come!
Ride does feel firmer in normal mode, but it feels like a plush sort of firm if that makes any sense...

it adds another suspension map, so you could have normal, sport, and track for example

sport mode which seems to me to be slightly more aggressive than OEM
normal, OEM sport being effectively useless on the street...

interesting you say that; I find the normal map noticeably more compliant than the OEM normal mode, to the extent I think its a little too soft, but I like the
sport mode which seems to me to be slightly more aggressive than OEM
normal, OEM sport being effectively useless on the street...

Question though, how do you activate the third mode if the current button only allows for Normal + Sport? It looks like DSC recommends the 2 mode option but just wondering.
Also one more, once installed how often would you need to update the software on the DSC unit? Is it worthwhile to keep a USB cable plugged in and tucked under the carpet somewhere?

therein to identify which mode you were in.
I believe that the v2 DSC for the 9x1 cars is currently 2-mode only - problem solved.
for the 9x1 cars, I think that the maps will evolve over time, so I would keep
a USB plugged in and concealed so that you can update with ease... I'm not
100% happy with the 'normal' mode on my GTS so I am thinking I might
tinker with it over time.
Also, if you were an avid track driver at various tracks, if you were serious
you could tune your 'sport' map for each individual track ...

Strictly out of curiosity - have you done a launch controled 0-60 in a C2s with and without this mod when you were bench testing? I'm curious to what the results of this would be since the name of the game is traction.

However, one of our dealers, Protuning Freaks, specialize in straight line performance and have reported back with very positive reviews of the DSC controller.
You can find a quick post they put up a few months back here:

They're a really great group of guys; if you'd like more details on their experience with DSC I'm sure they would be more than happy to speak with you.

Any word on AWD use? And in particular 991 Turbos?
