A few days and and several hundred kilometers with the DSC controller passed. Even though I haven’t used it on the course yet, I will share my impressions with you once I do that.

The DSC controller dimensions are 14x10x4 cm, it weighs next to nothing and it’s made of rugged plastic material. The front panel consists of two inputs: one is microUSB which is used to handle
communication with computer, the other one is the a main connector to which we plug the car harness.

The Controller can be mounted to replace the stock module, which is labelled as a fuel level control module. It is located in the boot – on the lef side, say, inner wheel arch. In order to reach it, the side velour matt has to be removed. The stock controller is fxed to the sheet metal with double-sided tape. You have to unstick and unplug it. Following, we attach DSC and plug formerly removed cable

Before I start writing about what maters most –impressions from the ride – here are a few more technical details. The tSB connector that I mentioned is implemented to connect controller to the computer, in order to exchange the configuration files provided by both: manufacturer and users. The later are given the access to software enabling them to individually tune the suspension. The
controller also has a WIFI module, thus it can be accessed this way.

So what’s the difference between DSC and the original controller? Well, since the stock controller allows us to choose between two modes: stiff and soft – the DSC constantly, dynamically and
independently controls the stiffness of suspension. That’s being done by calculating G forces, angular velocity of each wheel and the position of gas and brake pedals. Thanks to that, it works as an active suspension system which accurately responds to the chosen mode, so that the car feels even more comfortable when cruising and even faster in dynamic, sport conditions.

The new suspension modes are matching drive modes (normal / sport / track / drift and also the choice of stiffness, so we control it the old way. Bear in mind that the stock controller, suspension mode is either soft (in normal / sport / drift mode or stiff (race mode. When it comes to DSC, each drive mode has different shocks’ parameters.

That’s about it – when it comes to the theory. How does it feel in a real life? First question that comes to my mind is: Why the hell the car hasn’t left the factory like that? In a
comfortable setting (normal if finally feels comfy. Not like a limo – it’s still stiff and sporty, yet way more comfortable than it was before the upgrade. While crossing transversal bumps the machine won’t perform the ping pong dance anymore. It does inform us about the bump, but without unnecessary pogo. Sport mode differs from normal one cosmetically.

Independently controlled shocks significantly reduce lurches while braking, accelerating and turning. Owing to that turns can be performed faster, thus greater centrifugal force is required to throw the
balance of. I bet, this can also reduce the lap time.

To sum up, I would like to add something related to driving in normal/sport mode with stif hinge. Many of you justly assume that driving in this mode is quite unbearable. This setting, in a rather brutal manner exposed how poorly the asphalt was laid at recently put into service section of the motorway. At frst glance, the surface was looking super-smooth, however it turned out to be a complete wreck. Well, the builders should thank DSC manufacturers for making the impossible happen. RS is no more aa good tester for this type of roads. Finally, it’s possible to use stiffen mode on a daily basis without a need for visiting your dentist and physiotherapist too regularly.
