DSC does what it's supposed to do. I sum it up as if seems like the shocks react faster, especially at the track over bumps.

DSC Sport

We cannot speak for the car manufacturer as to why. I suppose it is the same scenario as the exhaust system and the braking system where both systems can be improved and the aftermarket has the solution.

We are sportscars/track enthusiasts in a position to produce a plug&play suspension controller and software that's designed for other enthusiasts who wants more versatility with no performance compromise.
One of many features of DSC is Velocity Tuning, which uses the car's existing ride height sensors to tune compression and rebound of the dampers in rear time. The OEM controller does not have this feature since the additional drivers aren't built into the controller.

Our standard calibration makes the ride softer in Normal mode, but not "soccer mom" soft. It can be adjusted to softer using our software but most users like our standard calibration as is. In fact, at a recent track event I asked a few GT car owners who already have DSC id they want the Normal mode to be softer they all said no, we like it the way it is. Nonetheless, the adjustability is there.

DSC Sport

Now, for DSC users who actually want the Normal mode to be another 5% softer or just want to try and see, we did make a calibration file that we named the "Tour" file. The only change on the Tour file is the Normal mode is made 5% softer than our DSC standard file. The Sport mode is unchanged from our DSC GT3/RS/GT2RS standard file.
This calibration file is available in the DSC Sport website for DSC users.

Premier Sportscar Service (P1) in Las Vegas did a complete alignment/component setup on my 2016 RS in November '19 primarily to add stability and even out the tire wear. Solid bushings in the thrust arms and rear steer actuators, significant camber added. Solid improvement on the track, eliminated the outer shoulder tire wear, and a bit more skittish on the street, but manageable.

We also added the firmer RS spring kit - and here is where I questioned my spring upgrade decision. Definitely stiffer on the street (not enjoyable), and weirdly enough, actually lost grip on the track - I suppose due to spring oscillation and 2016 stock suspension programming. Could not use the 'sport' stiffer suspension setting on track at all. Tight - bouncing and unpredictable in the mildly bumpy areas, hard to control bouncing off curbs, and no grip in the fast sweepers, even on the softer suspension setting.

Fast forward to a few weeks ago, P1 installed the RS v3 DSC controller. Night and day performance improvement! Very noticeable on the street - softer and more comfortable, very close to the original stock ride, even with the stiffer spring kit. And even more noticeable on the track. Grip returned in a big way - the car is super stable, well planted everywhere, and does not get upset easily, even in the bumpy, quick transitions. The stiffer DSC mode works very well, soft when needed and firm without feeling over-sprung.

For those who are thinking of upgrading the ride and performance of the 2016 GT3's and RS's, I highly recommend the DSC controller upgrade... low cost, high performance gain!

I did the full dundon system as well as the DSC on my 3RS. Both are amazing and transformed the car. Would do it again.

I am tempted by this for sure (DSC). I have. 991.2 Gt3 rs and there isn’t a huge amount of feedback on same, or would seem the gains are marginal. Has anyone got relevant experience they could share?

Hello, just curious, are the calibration files for a 991.1RS and a 991.2RS different or the same? It seems from the post that .1 and .2 are referred to as 991RS only, which makes it seem like the files being used are identical. If so, how can it work, on same cars with different spring rates?

Thanks!

I can attest to this; I had the DSC on my 997.2 GT3 and the improvement over the OEM PASM controller was very noticeable, the car was more "planted" and also "compliant" ...

I hated the OEM settings on my 991.1 GTS ... replacing the OEM with the v2 controller and installing the GT3 maps cured the worst of this, which I referred to as "porpoising" where the front rebound seemed to be more
aggressive than the rear ...

I waiting for TPC to get more v3's in stock and I'm going to install one in my '18 GT3 - long overdue ...

Larry I can’t see where I can pm you...send me a pm if you can.

For road comfort, the amount of improvement is less than that of a non-RS because the RS has almost double the front spring rate stiffness. The stiffer spring effect can't be removed with electronics but softer damper commands do make the ride nicer over bumps. This is noticeable.

For a race car driver, half a second a lap is big. Most of my weekend enthusiast customers report a second to two second improvement depending on track and skill level, the improvement is from car more stable near or at the limit.

Marginal is a relative term. I think with all things considering, a new DSC V3 is about half the cost of a set of tires, its a pretty reasonable deal.

The calibration files are the same. The factory Porsche Engineers did the job of pairing each model and each generation car with springs, dampers, and sway bars to achieve the performance level and feel they want. Basically, they engineered the suspension of each model car mechanically "from the tire up". To further enhance the suspension design on each model, DSC V3 controller using its proven algorithm to dynamically improve vehicle weight distribution to the driver's input "from the steering wheel down". So to answer more directly, each spring rate from the factory is "matched" to the dynamic range of each dampers. DSC operates within the dynamic range of each damper using them to their full potential.

its probably the best value for money modification you can make IMO - certainly better than an engine tune or ctr exhaust replacement! and simple to install

So I installed the dsc last night after a long wait (customs). Initial impression was not good as the shocks seemed to be full hard. It was punishing.

I dug out the manual and had a look at the config and worked out how to update it. I zero’d the ride height and put the TOUR settings on.

It was much better but it is so marginal versus stock and I would hazard a guess the dsc is firmer than stock. Hard to believe after all I have read.

My car is Weissach Euro spec with OPF and the last of the 991’s. The damping is so good from factory my guess is it has been developed further than first batch cars.

The difference in ride quality between mags and normal wheels is much bigger compared with with dsc in or out.

I will try and take a further look at the settings and will contact dsc for some setup help.

I have a track day on Wednesday so will run with the box in for the morning then swap out to oem for the afternoon.

Doing the change is a complete nightmare with 918’s and factory cage so I may take the seat out next time around.

You can't appreciate the DSC sport box until the car is being driven at its limits and run back to back testing. I found 0.6 secs at Palm Beach Raceway switching between the stock controller and the DSC Sport with their 2019 map for the GT3RS. I found a lot of extra time tuning the software to my preference (1.3 secs faster per lap compared to the stock unit).

DSC also allows you to have maps for street use, rain use, track use, it needs tailoring to individual use. I agree that the factory setup for shocks and springs is pretty good, but the DSC makes it even better.
