DSC controller -- help push me over the fence

The DSC controller has been out on the field for a while. Has there been any damper issues after many thousands of miles in areas with bad surfaces? The reason for the question is that the controller activates the damper valves with a higher frequency than stock, thus there's potential for faster wear (or perhaps not).

I had offered to allow a friend with a 997.1 a test drive with my 997.2 DSC module once we installed the 3 axis accelerometer. But now I'm not sure that was a good idea. Any thoughts or knowledge on backwards compatability from a .2 to a .1? Can we do this test drive?
seems like Tom @TPC is saying negative…
it’s odd to me that they wouldn’t work but I didn’t design the thing

I had my original 2005 C4s and I remember it being really stiff and jarring on the roads in NYC particularly in Manhattan, when I got back into a 2007 C4s last winter the first thing I was looking for was to see if they had something yo bring the suspension to be a bit more compliant as I DD in the spring/summer.
i went w the DSC controller w a NYC mapping and I couldn’t be happier w it. The car completely transforms over bumpy roads and you have much more confidence in the car. Sport mode feels better as well but just a plank over bumps.
i wouldn’t second guess it
I’m adding some B16 coil overs w pasm this spring so I can’t wait to report back how much better it is. The stock suspension only has 36k miles but pushing 14yrs so time for a refresh

Well, FedEx held my DSC box hostage for a week or so and surprised me with it today. Install was pretty simple. though you can in theory install w/o removing the under-tray under the glovebox, it helped me and those plastic screws take 2min to back out.
Clip out, and clip the new one it. Simple. No warning lights. Took it for a short drive and the very early impression is things in "normal" feel more supple. Hard to describe. A bit more stable and a bit more supple and planted. Will see as I take it on a real shakedown run.
Cool product. Love the plug & play. Will report back later after some miles.
FWIW, 997.2S Coupe, SPASM, 18" CarreraIII on DWS06 for year-round. 21k miles.

Great news! Agreed re: normal mode. Sport was a lot harder for me to tell, to be honest. Curious to hear what you observe.

A bit off topic but in line with DSC information, does anyone have the “NYC” map for a 997.2 DSC box available for download? Or any info regarding where it can be acquired? I’ve reached out to DSC without a response.
thanks for any help!

I run it on my 997.1 C4s in NYC and it’s night and day compared to the stock settings. The damping feels much better over bumps at speed

I talked to Tom two weeks ago and he explained to me the current version DSC doesn’t need map downloads because it has been optimized to adapt to all situations. After extensive testing his team feels that the current settings is the best possible so we don’t have to change anything.

Tom and I didn’t discuss legacy units because I was simply inquiring about buying a new unit and had questions about maps. Maybe someone can give him a call and share the info.

Does this mean they have a new map or that the new DSC has different hardware? Can the old boxes be updated?

I'm watching with interest, but my DSC is damn near perfect on real roads.
With it, I drive in SPORT mode 90% of the time.
With the OEM PASM box, it was 10%.
It feels to me like the enhanced rebound function is "pressing" each wheel independently back down against the road surface when an irregularity upsets the chassis.
A 'hand of god" effect is the best way I can describe it.
Expansion joints and shallow potholes are absorbed more compliantly than with the OEM, even in SPORT mode.
The real advantage of PASM over aftermarket hardware systems is having an active system vice static.
And the signals are sent exponentially faster to the valves using all four channels of the existing wiring architecture of the OEM system- that the stock box does not utilize.
Best $1K I ever spent on my car, easy.
