Darnit. . I've been on the fence on one of these for a while. This thread is not helping my wallet any

I procrastinated for about a year before I finally gave in and bought the DSC for my 2011 997.2 C2S. I didn't really understand how it worked and I was choking on the idea of paying over a thousand bucks for updated software. I even looked into buying 18" wheels with higher-sidewall tires, thinking that might offer a better ride quality, but that was way more spendy than the DSC.
Finally gave in and bought the DSC and I'm honestly shocked at how much more forgiving the ride quality is over our rough Wisconsin roads. And even a non-mechanic guy like me installed it in about 20 minutes. I got the regular/default map but am intrigued by the NYC map - I might look into it this year.

4GTS here. Not sure if it was a placebo effect because I didn’t feel any dramatic differences but comfort mode was slightly softer. Sport I couldn’t tell a difference. I couldn’t even tell a diff between sport and comfort suspension before the DSC swap! Maybe it’s all the extra padding on my *** lol.

My 997 GTS with PASM springs was transformed.
I don’t DD mine, so can avoid the worst roads in the LA area- but still, the freeway expansion joints and deep drainage gullies on secondary roads wreaked havoc in either NORMAL (soft) or SPORT (firm) modes.
OEM in SPORT mode worked very well in the twistys, when ride quality was not important. That said, any road surface irregularity mid corner would unsettle the chassis and affect grip at the most critical part of the turn…apex into exit.
The DSC box has tamed the beast.
Read the technical description, but it reacts exponentially faster, and with a wider envelope of firm/soft shock adjustment.
It also samples and controls all four shocks independently, a hardware option which the OEM PASM box did not exploit.
The ride quality is improved in both modes, and the SPORT mode is now tolerable on rougher roads and it has improved my confidence in the canyons and mountains. At the limit, rocks are my only remaining nemesis as ruts, bumps and swales mid corner do not upset the chassis like before. Rear wheels remain planted and car no longer rotates un-commanded when one or both contact patches get light or airborne (!) mid corner.
Squat under acceleration and dive under heavy braking are both reduced, likely due to the improvement in reaction speed.
I have not sampled any custom maps; really don’t feel the need as my car is both ridiculously agile and compliant now.
No other suspension mod is cheaper, as reversible and simple/quick as the DSC box.
For a grand?
Used boxes sell for the same as new.
Zero risk.
A real no brainer decision, IMHO.

Not to thread jack, but since we’re on the topic anyway….. There seems to be a difference between the 997.1 and 997.2 DSC? When I see them for sale in the marketplace every once and a while, the ads always seem to distinguish by generation. So is it just that the 997.1 requires an accelerometer?

Yes, only the 997.1 needs an additional accelerometer. The 997.2 has it from the factory. The question I asked and got mixed answers is can I used a 997.2 dsc in a 997.1 but add the accelerometer… seems like it should work

Yeah, I was wondering that as well. I was going to say that since they sell pretty much the same when new or used, may as well buy new and eliminate that as an potential issue. But it seems they can be found for $1K where new without the accelerometer from DSC they’re $1290. Accelerometer runs $250 from DSC, so it might be worth further investigation.

Anyone know of a source for a working coupon code from DSC?
