Transform the handling of your TTRS with the DSC Sport Controller! The DSC Sport Controller is a Plug N Play active suspension controller that replaces your factory DCC control module and works with your factory active suspension. With our revolutionary tuning strategy, DSC Sport provides your TTRS with better track handling and improved daily comfort. DSC Sport will greatly improve your everyday ride, all while offering improved grip and reduced squat, dive, and roll on track!

By expanding the dynamic range and rate of response, DSC Sport is able to utilize more sensory input data and provide real time damping solutions. By gathering G Force, Brake Pressure, Steering Angle, Speed, Acceleration, Shock Calibration, and Velocity; DSC Sport adjusts each individual damper in real time to provide the most optimum damper performance both on and off the track.

Our controllers have been proven in the Porsche community for many years, ranging from 100% track cars to those people that just want to have fun on the backroads on a nice weekend. We been expanding our product line consistently since then, including Dodge, Ford, Nissan, Cadillac, Chevy, any many more custom applications running a standalone kit. We have been met with great success in all of these platforms and figured now was the time to move into the VAG community.

All of our controller come pre-calibrated with a suspension tuning file that we believe will be adequate for most drivers. So if your one of those, its something you can install, get all the benefits and never have to worry about again. But for those with specific needs for the track, wether it be the drag strip or the road course, the controller is 100% tunable on your end. Using the DSC Sport Tuning Software, users can custom tune their suspension to personal preference. Set maximum and minimum damper rates and tuning characteristics for various driving scenarios, vehicle setups, and personal preference. DSC Sport puts the power of a suspension engineer in the palm of your hand.

Installation for the TTRS is a very simple process and should only take you about 30 minutes, just swap out the factory module for your new DSC controller. The factory module is located under the passenger seat, just unbolt it and tilt the seat back to the rear. A write up for the install will be available on our product page for the controller.

This is great news! I’ve seen and heard great reports about DSC Sport from the Porsche PASM world.
Could you go into more detail about the offering for our cars, including:
- Is the calibration specific to the TTRS and different for the RS3 and S3. I’d expect, but may be wrong, that the calibration in my oem unit isn’t the same as the calibration for the RS3 or S3.
- How would the two modes be different to oem? Will Dynamic have the potential to go stiffer when needed. Will comfort be softer?
- What does the DSC do that the oem controller doesn’t?
- be good to hear some feedback directly from TT/RS3 owners; even better some laptime comparisons oem vs DSC

Thanks for bringing this to market and I’m very interested in learning more!

We have been testing calibrations for the last year on multiple RS3 and TTRS's. We have found a middle ground that works for both cars amazingly out of the box. But as with any of our controllers, it is 100% customizable and can be tuned to any users liking and needs. As for your question about the variations between modes, we change the dampening curve, rebound, and stiffness of each corner in simple terms. Unlike the factory, Our module utilizes the factory sensors to monitor G Force, Brake Pressure, Steering Angle, Speed, Acceleration, Shock Calibration, and Velocity, and the tuning for each mode will read these inputs and adjust accordingly. The factory module does adjust dampening but it is only semi active. Meaning it does set a different dampening in each mode, but it won't be fully active, where ours will stiffen up one corner and soften another depending how hard you take a turn and then continuously do that the entire way around a track

I can speak from personal experience that the DSC module is a game-changer in terms of improving the suspension. I have one in my 981 GT4 (that's a Cayman for the unenlightened), and it improved the ride quality of the regular mode, and greatly increased the car behavior in PSM Sport Mode. For the regular mode, it made the car more streetable, tuning out the inherent stiffness or bang to the frame that the car has from the factory when one rolls over small bumps. And for Sport mode, it greatly reduced dive and body roll upon hard cornering, allowing for faster lap times, and better wear on the tires. I tend to think of it as a coilover cheat, as it provided my already great car with even better drivability and handling without having to shell out dough for coilovers + labor + suspension dialing (which takes a while and eats up track time). Their support is also great, as Tom always makes himself available to me.

So, in terms of the TT-RS, can you guys share what we could expect from the COMFORT and DYNAMIC Modes? Is Comfort plushier, less bouncy maybe? And is Dynamic softer sprung in a straight-line but tightens up when lateral load is placed on the corners? Might your tune help mitigate some of the inherent PUSH?

PLEASE SHARE!

Intriguing. It would be interesting to hear what the new shock setting are configured for spring wise. Most performance seekers will want at least 10k springs front and rear. What is the effective range of springs that you can run on the stock magride shocks before they are out of spec?

[DKo5]

Despite the lack of TT-RS info I went ahead and ordered a unit. As much as I dislike how "4x4" the TT-RS looks on stock suspension, I really don't want to go back to the days of scraping on every bump or driveway - so I'm hoping the DSC controller will improve handling enough to keep me from throwing on some MSS springs. Unit should arrive on Monday and I'll be going Uni stage 2 on Wednesday before hitting the track on the 30th. I'll try and write up my impressions, but be warned that I am not a highly skilled driver (this will make track day #4 for me) so my review might not be all that interesting.

Received, installed and tested a DSC Sport Controller in my 2019 TT RS with OEM mag ride suspension and OEM 20's with non run flat Pilot Sport 4S

Ladies and gentlemen, this is the real deal.

I started with comfort mode. It was a noticeable different driving down the hill from our neighborhood 1.25 miles to the main road. Around town at 45 MPH and below, its very compliant. It surprised me, really does ride better.
Road noise is the same and you still feel the little bumps. It's a sports car. However, the suspension articulates way more than OEM. At higher speeds, it "floats" as some say.
It feels like it squats under braking. Speed bumps at parking lot speeds are no where near as harsh.
I could tell the difference between comfort and dynamic.
Dynamic mode feels similar to OEM comfort but with more suspension travel.
I have more miles to drive to evaluate and acclimate to the differences. To me, it's worth it for the ride improvement alone.

Is there a race setting or something like that? I have look at this a few times but never pulled the trigger. If it can add to comfort and make lap times better im game.

It does. If you check out the software settings (this is stock), you can see the difference in front and rear shock settings under braking. DSC Stock TT RS Brake Settings

are you saying the car still floats with DSC controller at high speeds??

[DrMerl]

If you don't want to switch to coil-overs the DSC controller is a great improvement over the stock controller.

I'm using this on a 2019 TT RS with 265/35/18s on 034 forged rims, 034 springs and all other 034 suspension parts installed. I'm working on a street tune file for my setup, suggestions from others have worked well. For me I drive in Dynamic only and have yet to adjust the DSC "comfort" mode to my liking, so it's disabled for now. After dialing in more rebound control the faster you go the smoother things get (without losing feel of the road), road imperfections here in So-Cal are not so much of a problem anymore.

The improvement of anti-dive and selective "stiffening" of a corner(s) based on load/speed is transformative on the street. There is a launch mode too. There are a lot of video explanations and instructions on the DSC site. If you go with this controller and don't utilize its tuning ability better to stay stock.

[8STTRS]

Thanks for the feedback there, DrMerl. I had a DSC Sport on my C7 Z06 and I loved it. I also increased the rebound and found it to be much improved. I may be in contact with you in the future about your setup and the adjustments you made to your settings. Are you running aggressive camber at all?

I'll be happy to share a config file or data set. There's great deal of data available for Porsche and the Corvette, but I can't find much specific for the RS3/TTRS yet.

I am using the 034 front camber plates.
Current alignment is for street w/ some braking stability -
Front -
Camber : -3.0 deg
Caster : 7.1 deg
Toe: .6mm (in)
Rear -
Camber: -1.5 deg
Toe: .8mm (in)

Excellent improvement for me and the 034 parts combo. More confidence on accel and braking, "flickable" in transitions, rear end follows nicely but is not jumpy. Pretty darn good for a FWD based chassis IMO and not going crazy with suspension.

My current DSC file has -
Under Velocity +5% under Zero, +10% for Reb-Low, Reb-Med, Reb-High
G Comfort - G Rate Max is 0.0

These settings have made 70-120MPH cruising effortless on the bouncy, unpredictable freeways around here. Other cars are basically pylons.

It is not soft by any means, more like very, very sporty, you're gonna need to hold your Starbucks cup for some freeway bumps. Going to Comfort setting in Audi Drive now is worthwhile when cruising local streets.

I'm going to test out slightly less compression to see if I can smooth things out a little more without resorting to G Comfort.

Goal is to absorb bumps the same way a cat or a Baja truck lands.

[8STTRS]

Is your camber in the rear neutral?

[DrMerl]

Is your camber in the rear neutral?

There's a bit of negative (-1.5) to lean towards cornering grip (for street). To utilize I've stiffened up the rear with 034 RSB (soft setting), 034 spherical end links, 034 spherical trailing arm, 034 street density rear shock mounts. After I added the rear trailing arms I think the ride improved nicely (no additional noise), more predictable under load. Audi did an amazing job keeping things tame, comfy and quiet, but so much is left on the table if you're an enthusiast.

[MESOGLEA]

Someone said a DSC unit is like an ECU/TCU tune.
I agree.

[McTTRS]

I agree.

Seems to have that impact on the suspension but you are replacing a dumb as a barrel of rocks untunable computer that controls all the suspension corners the same based one ride height sensor with a user tune-able computer that controls each corner of the suspension independently based on a full array of sensors. To me its more like going from points and a distributer to a tunable ECU based ignition system.

[Cyttorak]

@DSC Sport - Was about to pull the trigger today when I discovered this by mistake. Put the controller in the cart, shipping zip and got $38.65 in shipping then realized I forgot to add the signature required for $0 and recalculated. The shipping cost increased @50% to $57.79.

Is this accurate? Or a website glitch?

Thanks in advance.

I just got the dsc sport controller and feel like I can improve on some aspects of it. Something that really bothers me is the overall bouncing after harsh bumps. Did you experience the same?

[Cyttorak]

I’m experiencing the same thing in comfort mode. Like a bounce house

Add +5-10 in the G-Comfort > Default Rate. This should help with the bounce when you're cruising with zero G. Load the latest config file from their website. A totally different way to control things as far as settings. It's good so far after several hundred miles, but I've still added to the Default Rate to help with bounce (added +5 so far).

[slammin86]

What file are you referring to? I have tried both the stock spring file and the mss spring file.

[McTTRS]

What file are you referring to? I have tried both the stock spring file and the mss spring file.

The original config files were dated in 2021 but OEM damper file was updated on 4/8/22 and is a lot better starting point. I then added +5 g-rate and +5 sensitivity and like the result - less floating.

Yep! I went through lots of fiddling with numbers on the previous files, the new file is a way different approach. It works better than before regarding control at high speed, with G force and hard braking.

I right away did the same additions to the settings, I do not like the floaty Caddy feel when just cruising. The roads and freeways around here are not good for a hobbie-horse ride.

This is the file to get -
https://www.dscsport.com/wp-content/...only.pdts_.zip

I'm using 034 Motorsports everything for suspension bits on my TTRS, the new file handles the quicker response from the hardware in a nicer way. This is sharing from a street only car.

[DrMerl]

Just did a loop drive I usually do, it's about 200 miles.

Using the latest DSC config file from 04/08/22, I applied +5 Default Rate and +5 Sensitivity under G Comfort Parameters for all three tables (Normal, Sport, Track).

I rarely use Comfort or Auto or Individual settings, 95% Dynamic mode.

My route is San Diego > 5 North > Highway 1 through the OC to Newport > 91 East > 215 South > 15 back to SD. The roads and freeways can go from glass to ass one mile to the next. When the 5 is open Northbound it's great, there's a lot of construction and speed monitoring areas, the freeway is 80% smooth with a few places I use to test settings. New settings gave a little more controlled ride (nose can bounce) at Zero G, wasn't as bouncy as initial file settings. It was close but I prefer a stiffer ride at zero G with the DSC.

I added a little more to Default Rate and it helped very nicely with a firm, sporting ride. The 91 is a horrible freeway in some areas, most of time the concrete patches are cupped (do the Porpoise dance) , with sh1tty repairs, height differences between patches can be a few inches and big grooves to catch your tires for tram-lining (that is not fun at WOT when you're suddenly being yanked left or right). If you can get a decent ride on a sports suspension over this freeway, you're doing pretty good. Adding a bit more to Default Rate worked well.

Here's what I have now -
Sport table - Default Rate:18, Offset:30, Sensitivity:17, G Rate Max:18

There are ton of ways to adjust, with many that do not seem related, but it's all a system with tables building on tables, the new file is a pretty different way to achieve good/different results. I like the direction of the config file changes, lots more to learn though.

265/35/18s on 034 rims, PS4S, 38psi F/33psi R (cold). 034 RSB soft, 034 spherical endlinks, 034 trailing arms, 034 rear shock mounts, 034 subframe collars, 034 camber mounts, F/R 034 floating rotors. Stock alignment except for the added camber from the 034 mounts. Had a bit more toe earlier and it was way too squirrely for higher speeds, but perf for canyon carving.

On order is a 034 FSB with spherical links and the new camster mount pair (a bit of fixed caster and camber). Also going try out 275/35 Conti shoes, they are lighter than the 265/35 PS4S's. Love to ditch unsprung weight when it's available.

You’re not kidding about 91. The first time I drove on it with e85 the other day was quite the experience just keeping it straight while wot. As you said, I was getting pulled to either side and it was pretty violent too. It actually scared me and I quickly slowed down. Can only imagine what that’d be like with an upgraded turbo.

I'm glad I'm not the only one feeling this, yeah, setting things up for street takes another approach on this chassis. 500-600HP is pretty stoopid for such a small vehicle. The stock alignment settings are tolerable, it's nice to have an active and responsive suspension, but there's a limit for street and the crazy roads. Removing unsprung weight helps a lot. More fiddling with DSC gives a very nice, steady WOT at any speed - but again, those damn ruts. I'm going to add more punishment by trying out wider (275/35/18), but lighter tires. Hoping the new 034 "camster" shock tops will help with straight line stability.

[DrMerl]

Going back over the DSC config video. I think I'll go back and reduce the Sensitivity number, I want it to change more quickly from G Comfort to standard G force based rates. So I'll go back to the original number for Track. May reduce G Rate Max to 15 or 12 - that's .15 and .12 G's on the Audi meter, a small direction change at speed is .1G.

[Cyttorak]

Doubt if it’s related but can’t help to have that feeling cause only thing I did was update my DSC controller as suggested by DrMerl. To get that bounce/caddy out of the comfort made.

Then within 5 minutes of the update, was going WOT to get on the tollway by my house and seemingly every warning light/message came on.

Steering malfunction, speed control systems, safety systems, esc, abs, headlights, homelink didn’t work to get back in my garage.

Lol, not a Sunday funday for me.

I take it nobody has experienced any of this after updating?

I have updated the DSC unit a half a dozen times or so without issue so based on my experience the two events may be totally unrelated.

Edit - I contacted DSC with your post and they said "Thanks for the info. I change calibration files all the time on DSC controllers and have not experienced what that user described. It is possible that he did something different that caused the suspension controller to freeze. In saldom cases, I have heard of people doing ECU flash that's followed by a hard reboot that draws a lot of battery power which can freeze the suspension controller if the battery itself isn't fully charged or in excellent condition to begin with. That user should contact us ([email protected]) for diagnosis..."

Woah, never any problems while working with the DSC controller. Can do changes on the fly, car running or not. The only time you'd turn on the ignition, but not engine, is right before you reset ride height. This allows the sensors to power up, you will get one engine symbol check light after this. Turn off ignition and all good.

Check the USB cable, maybe it got pinched and has shorted slightly to freak out the bus. Make sure the OEM connector is seated properly and no pins are bent. Gotta unbolt and tilt the seat back to get enough access to see. I leave the USB cable connected and tucked under the seat.
