DSC Sport Suspension Module for our cars!

[Winpildeu]

One more update after driving on the highway around Florida revealed some NVH was introduced in v1.3. So this is more of a refinement to reduce some of the NVH w/o losing all the feel (kind of a compromise)


This changelog tracks the evolution of your "Chassis Touring" map from v1.2 through to the current v1.4. These changes are specifically designed to optimize your DE5’s ride quality for the street while accounting for your aftermarket hardware: Spoon progressive springs, RV6 rear sway bar, and the Spoon Crane Neck Wing.

"Chassis Touring" Evolution & Changelog

Map Version	Key Settings Changed	Why the Change was Made?
v1.2	Baseline Map	Established the initial 4% Default Rate intended for maximum cruising comfort.
v1.3	G-Force Baseline: 4%	Logic Correction: Synchronized the G-Force floor with the 4% Default Rate. This ensures the dampers can actually reach the softest setting, allowing the 10% stiffer Spoon springs to soak up road chatter.
v1.3	Brake Front: 50%	Pitch Control: Proactively stiffens the front to manage the weight transfer from the high initial bite of the Endless MX72+ pads.
v1.3	Accel Speed Limit: 60 MPH	Aero Integration: Fades out electronic anti-squat as the Spoon wing begins providing physical downforce stability at highway speeds.
v1.4	Sensitivity: 25	NVH Filtering: Acts as a "noise filter" for the stiff RV6 Rear Sway Bar. Higher sensitivity prevents the DSC from over-reacting to one-wheel bumps and high-frequency road "noise".
v1.4	Hi-Speed Compression: -45%	Bumping Compliance: Lowered from -25% to -45% to specifically target "harshness" on rough highways. This allows the wheels to move more freely over sharp expansion joints, preventingjolts from reaching the cabin.
v1.4	Low-Speed Rebound: -5%	Plushness: Slightly reduced to allow the suspension to extend more easily over small ripples, creating a more "supple" feel around town.

Summary of v1.4 Enhancements
The primary goal of v1.4 was to address NVH (Noise, Vibration, Harshness) encountered during highway testing with the previous version. By significantly lowering the High-Speed Compression (-45%), you have tuned the dampers to "blow off" the energy from sharp bumps rather than resisting them.

Combined with the increased Sensitivity (25), the map now effectively ignores the mechanical "chatter" of the RV6 sway bar. This allows the Spoon progressive springs to handle the car's primary weight while the DSC software manages the small, high-frequency "hits" typical of rough street driving.

I’m glad to see the analysis and feedback; I really hope more take advantage of the opportunity here.

"Chassis Touring" Evolution & Changelog

v1.4

Hi-Speed Compression: -45%

Bumping Compliance: Lowered from -25% to -45% to specifically target "harshness" on rough highways. This allows the wheels to move more freely over sharp expansion joints, preventingjolts from reaching the cabin.

With that being said, please be careful with significant high velocity compression deviation from medium and low velocities. You want the suspension to be predictable, especially in scenarios where there is a sharp change.

I can't keep up with you guys, but just know I want to. I haven't had time to mess with the car at all since I had the unit installed- barely time to drive it.

Also I want to get it out to autocross and track. I'm thinking on a long enough timeline I'll have 3 separate maps for each setting. But I want to try the baseline first.

Stand by, I plan to be an active contributor at some point too.

With this input and further tweaking, I've arrived settings I'm quite happy with in most scenarios on the road. Comparing his settings and mine, there's quite a bit of similarity. This will likely be the last update from me for this comfort map unless there are some glaring issues identified. People give it a test and let me know how it feels w/ your setup.


Here is the detailed changelog for the "Chassis Touring" map. These updates focus on perfecting the balance between high-speed compliance and chassis stability for your specific hardware configuration.

Changelog: "Chassis Touring" v1.4 vs. v1.5

Parameter	v1.4 Value	v1.5 Value	Why the change was made?
G-Force Sensitivity	30	35	Increased Filtering: A higher sensitivity value acts as a stronger electronic "shield" against the mechanical noise and sharp kicks from your stiff RV6 rear sway bar. +2
High-Speed Compression	-35% (650)	-45% (550)	Compliance: Lowered to the maximum comfort threshold to allow the shocks to "blow off" energy during rapid vertical impacts like expansion joints. +2
Low-Speed Rebound	0% (1000)	+5% (1050)	Control: Increased to provide better body control and a more "planted" feel during initial turn-in and braking transitions. +2
High-Speed Rebound	+10% (1100)	+15% (1150)	Aero Management: Increased specifically to "catch" the extra energy from the Spoon Crane Neck Wing and Spoon springs during high-speed highway dips. +2
Gradient Smoothing	Discrete Steps	Linear Ramp	Predictability: v1.5 uses a smoother mathematical progression between values to ensure the car's behavior remains consistent as shock speeds increase.

How the car will feel in v1.5
On the Highway (High-Velocity Impacts)

• 
  The "Blow-Off" Effect: With High-Speed Compression at -45%, the car should now "swallow" sharp highway expansion joints and bridge transitions much more effectively. Instead of a sharp, metallic "thud" being sent through the chassis, the wheels will move upward more freely, significantly reducing NVH (Noise, Vibration, Harshness).
  +4
  
  
• Rear-End Stability: Thanks to the +15% High-Speed Rebound, the rear of the car will feel more tied down at 70+ MPH. When you hit a large dip, the extra downforce from the Spoon wing won't cause the car to "pogo" or bounce; it will compress and then return to a level state in one controlled motion.
  +1
  

On Backroads (Low-Velocity Transitions)

• 
  Sharper Response: By moving Low-Speed Rebound to +5%, the car will feel slightly "tighter" and more responsive to your steering inputs compared to v1.4. The car will take a "set" faster in corners, reducing the feeling of body roll without adding harshness to the ride.
  +1
  
  
• 
  Mechanical Isolation: The increase in Sensitivity to 35 ensures that while the car feels sharper, you aren't feeling every pebble or minor crack in the road. It effectively "muffles" the extra stiffness of the RV6 sway bar during straight-line cruising.
