Our Dynamic Suspension Controller replaces your factory suspension control module to gain full control of your factory shocks. The DSC uses an advanced active control strategy that responds to conditions to command stiffness of the shocks in real time. Additionally, the DSC uses the full operating range of the shocks where the factory controller uses only a fraction.

Occasionally, our controllers are listed for sale or resale using outdated "V" version notation.

These notation was historically used to represent a style of controller, with 997 models represented as V1, 991 controllers represented as V2, and several other models represented by V4.

In 2020, following a hardware revision to 991 applications, the revised application was referred to as V3. "V2" 2019 production year 991, 718, and 981 controllers are no longer sold directly through DSC. All 991, 718, and 981 applications sold by DSC Sport are "V3".

To eliminate confusion, we no longer utilize this system. All DSC controllers variants have individualized SKUs. Review below to better understand compatibility.

DSC controllers are vehicle generation specific.

Ex. 718 and 981 are two different vehicle generations and are not interchangeable. Please use the selection menu to select your accurate vehicle generation when purchasing a controller. If you make a mistake while ordering, please contact us as soon as possible to make a correction.

Some of our controller types share a case style. This is inline with OEM manufacturers, where case styles for suspension controllers are shared between different makes and models. Ex. Porsche 991 and Hellcat OEM suspension modules share a case style.

While these controllers make look the same, the internals and firmware are different and not cross-compatible. This is true both for OEM and for our product.

We cannot guarantee compatibility on aftermarket purchases, and our staff is unable to confirm compatibility or make any claims to that effect. The below information is included as a courtesy but DOES NOT represent any guarantee in regards to compatibility.

If you are purchasing aftermarket and want to determine compatibility: The only products that are cross compatible are controllers that share a generation but not a sub model. Controllers for the same vehicle but different generations are compatible only with in-house conversion. This service is offered for $350. If you are the original purchaser, contact DSC Sport for information about your options.

Scenario 1: Customer 1 buys a controller for their 718 Base Cayman from DSC Sport. A few years later, they sell it to Customer 2, who owns a 718 GT4RS. The controller is compatible with Customer 2's vehicle, but will not contain the optimal calibration file. Calibration files/calibration conversions can be purchased from our website.

Scenario 2: Customer 1 buys a controller from DSC Sport for their 718 Cayman S. Later, they sell it to Customer 2, who owns a 981. These vehicles are from different generations, and the controllers are not plug and play cross compatible. We can convert between these models for a fee. This is in line with other model-specific electronic products in the automotive performance space.

Scenario 3: Customer 1 buys a controller from DSC Sport for their 718 Cayman S. 3 months later, they sell their S for a GT4RS. This customer is within the support period and is eligible for a new calibration file, free of charge. Contact us for more information if this applies to you.

Scenario 4: Customer 1 buys a controller from DSC Sport for their 718 Cayman S. 3 months later, they sell their 718 for a 991.1 GT3. This customer is within the support period and is generally eligible for conversion. Contact DSC Sport for details.

By utilizing the full capabilities of your shocks, you will notice your car responding better to changing conditions, adapting in real time to the road and your driving style, and improving comfort and performance overall. Noticeably, you might not feel a difference immediately when changing modes in the way that you do with an OEM module. This is because a DSC module responds to numerous inputs, like steering angle and g-forces to respond to reality rather than make a prediction based on the mode. With a DSC module, modes instead control the range you want your module to operate within (with overlap between modes to improve comfort and reduce the need for constant switching). i.e. in Comfort, the range is on the softer end of the spectrum, whereas in Sport the range shifts slightly stiffer.

"This car is predictable, it's extraordinarily fast, it rides beautifully. This track is medium bumpy, but nothing really seems to upset it.”

-Matt Farah, C7 Z06

“It’s game changing and truly transforms the cars performance. I have a hard time putting into words just how transformational the DSC Sport Controller is in EVERY driving situation. The handling gains during aggressive street driving and on the track are shocking. Hugh improvement over the OEM controller. Just truly amazing.”

— Rikhek, C7 Corvette

Yes. DSC Sport spends countless hours testing and tuning before releasing support for any vehicle. Each DSC Sport controller comes from our facility loaded with a calibration file optimized for virtually all users. In most cases, minor suspension modifications, such as lowering springs for example, do not require updating the calibration file.

If you purchased aftermarket or would like to request specialized assistance in creating a custom file for your needs, contact us to inquire.

No, DSC Sport does not add any stress to the factory dampers or other suspension components. In fact, the factory control method sends a constant current to the dampers, while DSC Sport alters the current and utilizes a series of on/off commands. Under normal usage, DSC Sport will ultimately send less current to the dampers allowing for better cooling during usage.

On June 27, 2025, thanks to the in-depth work of a user and our in-house engineering team, DSC Sport was made aware of a bug in our 718/981/991 controller line.

Since being made aware of the matter, the team at DSC has worked diligently to test the controller, isolate the bug, and identify the models potentially affected. Ultimately, we have identified one bug in one controller line. Our findings are summarized below, for clarity and accountability.

1. DSC confirmed a minor bug in the firmware of the 718/981/991 controller model. This human error was buried deep within the initial programming, and ultimately went unnoticed due to the fact that we completed extensive testing and tuning based on road and track driving with professional drivers’ feedback. (i.e., in the driving portion of the development process, real-life programming was done over the virtual starting point to achieve desirable results in the finished product) The comfort and performance that you have felt and loved for years is real, as a direct result of real-world driving and tuning over the starting point.

2. The bug only affects the g-force table output and only if the g-force table output is custom programmed asymmetrically for perceived channels. The scope of the bug is very limited and according to our team’s analysis, affects a very limited number of users who did custom tuning to the g-force table with deviating lateral outputs.

3. The vast majority of users using our calibration (tune) are unaffected by unintended behavior. We continue to stand by the tune we produced while acknowledging that there was one limited error that we have since discovered and corrected in future iterations. Due to the fact that there are numerous other inputs and outputs used by our controller, we ultimately tuned over the bug without realizing it and produced a great product. This has been verified by our race-winning team of professional drivers as well as independent sources.

4. There are three separate production ranges (based on the version the controller reads out):

5. 718/981/991 pre-2018 versions

6. 718/981/991 2018-2020 versions

7. 718/981/991 2021-2023 versions

In all versions of controllers, the out of the box intended performance is unaffected. We have provided below a voluntary self-service update.   As of 07/01/2025, all new controllers will be shipped out with this update.

Suitable for the majority of customers and users:

If you are using the controller as delivered, no action is needed. You are unaffected and will continue to receive the optimal driving experience. The self-service update is entirely voluntary.

Suitable for customers and users that wish to extensively custom tune:
