I'm also curious. I've been wanting this module but its gonna interfere with FAL.

What's the sunroof issue?

 

I'm running the V3 on my .1 GTS with sunroof but no FAL - highly recommended!

 

 

Well compared to the GT4 which had the Tarett spring upgrade and monoballs all the way around it feels pretty plush but I can't say I noticed any before / after differences in the non sport setting. My car does have SPASM.

 

just call tom at tpc and ask him

 

It was posted on 8/26/18 by JW1 (an "early adopter" affected by the problem) that he had received a module with a firmware update that fixes the problem (I confirmed this with Tom via email). This prompted me to order one (the order page now asks if you have FAL and / or Sunroof to make sure you get the right firmware).

I've had the DSC V3 on my 2017 991.2 TTS with FAL and Sunroof for a little over a week and absolutely love it. It really transforms the car.

 

Can someone explain to me what this actually does? Transforms the car sounds great but, how? THX

 

DSC is a new Suspension Control Module/Computer. After reading review's on the GT4 and GT3 forum, I purchased one before my car arrived. Drove the car for two weeks with Porsche standard PASM and then installed the DSC. Amazing and the statement on their web page sums it up perfectly.

In a nutshell, it dynamically adjusts the vehicle's electronically adjustable suspension components (shocks and dynamic engine mounts) on the fly - reacting to things like g forces the car is experiencing, throttle position, brake fluid pressure. It stiffens things up when necessary and softens them when not necessary. On the track you can get a flatter more stable platform which increases traction and allows the car to be driven harder (and reduces lap times) and on the street it allows for softer damping (for a more comfortable ride) but still controls body roll when cornering, nose dive when braking and squat when accelerating. The factory PASM controller scratches the surface of an active suspension; the DSC does a much deeper dive into the car's real capabilities.

 

A hugely simplified explanation that glosses over a ton of detail and nuance:

- Factory setup has two suspension modes — normal and sport. Normal is soft-ish, sport is firmer.
- The factory dampers have the ability to be adjusted through a range of stiffness. Let's just say for this example normal is 30%, sport is 70%.
- The DSC module lets you change these stiffness settings for the dampers, not just as a static value for these two modes but based on cornering g-forces (among other things). So, 0g --> 1g can see a damper adjustment range of 20% to 100% stiffness, all controlled in real-time. The harder you corner, the stiffer the dampers become.
- Factory PASM controller (which you swap out and replace with the DSC module) doesn't really have this real-time adjustment based on cornering G force. This is what people say about the difference between passive and active suspension — set at one stiffness value vs constantly variable depending on G force.
- You can reduce the front-end diving under hard braking by the same calibration of cornering G affecting damper stiffness, but instead on the fore/aft G force value. Same with squat in the rear as you accelerate.

Again, lots of details left out but that's the gist of it from my own personal experience.

 

Yes!

We have received very positive feedbacks from 991.2 Carrera, Carrera S, Turbo, Turbo S and GT3 owners.

 

 

 

My research on dsc basically found explanations matching what you described, but I still don't get the difference between that and oem pasm. https://youtu.be/5a6NfyHUbFU according to this marketing video for the 997, pasm is actively monitoring road conditions and driver input to adjust the dampers. So at the end of the day, both systems are doing the same thing, but just a different tune? That makes me wonder why Porsche didn't tune it the "right" way to begin with. And why a 3rd party can do a much better job. It would make much more sense to me if the dsc module had additional sensors or inputs, but for the 991, it doesn't seem to be the case. Would be great to get some more insight on this.
