All. I've decided to release all of the files I've created as calibration files, because the volume of individual requests I have received is completely overwhelming.
These calibration files may or may not work for you. They reflect my philosophy in making these files. Obviously I cannot test them all, but in general the ones that have a higher version number have been refined more via feedback from people with that specific setup. Some of them may be fairly wide of the mark, others less so.
The files are located at DSC Files - they're a bunch of different DSC calibration files that may work for you. I've tried to name them consistently.
If you have not applied the DSC patch for correcting the swap of the L/R output channels, you MUST APPLY THIS BEFORE USING THESE CALIBRATION FILES. Failure to do so will result in an unsafe situation for driving.
Note that nitron and tractive files are not interchangeable. Similarly for the Bilstein files, although these are compatible with the OEM struts.
Use at your own risk.
I will provide zero - and I mean ZERO - support for them, and expressly disclaim ANY liability or ANY fitness for purpose.
In other words - I will ignore any DM asking me for help.
You should upload them to github! Thank you for the files!
I have been running V3 since 2024 (OEM suspension) on the supplied software that it was shipped with. I have a simple question. is there a calibration in this archive that would be a more effective choice? I don't track the car.

I have the same question. My DSC is a 2026 new purchase edition for a 991.2 4GTS with PDCC, and I would really like to add a KW HAS to it, but I don't know how it will perform. Also, I don't track the car.
an imput would really help .thank you
My current suspension setup is Stock Dampers with the RR racing coilover over kit with 450/600 lb springs.
I have taken some of Enzo's files, and im trying to readjust the velocity table. Being that he released some files with 70nm springs and some with 110nm, i find the to be closest to what im currently running (not perfect, but close to...)
I used a combination of two tractive files to equeal a 70/110 calibration, and imputed it into one of his Stock damper files.
Is this just blatantly wrong? My assumption is that a spring rate is a spring rate, and the shock, being electronically valved, can be modified.
HOWEVER.. My worry is because the tractive dampers react much MUCH quicker than OEM, that with values i used, the shock wont be able to keep up with the values i took from the tractive files. (please note: im not uploading a tractive file to my stock dampers because the shock calibration chart's mA would probably blow up the stock dampers.)
I went ahead and tested my new file with the 70/110 calibration and DAMN it feels good.
Shoutout @enzotcat for an amazing base file that i was able to turn into something that works great for my custom application
Ok maybe for slower canyon carving but uhh.. way tooo soft when theres bumps in the turns. Felt like i was driving a 03 expedition at times LOL
Back to the drawling board.
Am i stupid in thinking that the lower the number for compression and rebound, the less it does? Meaning it would be stiff depending on the G the car is pulling?
Where im having issues is more so in the straits as thats where the car is the fastest. Bumps and deviations, while feeling like a Bentley, its unsettling the car to the point where i lose confidence.
Maybe im driving the car too hard for a "public" back road in Oregon.
Edit.. Just watched Enzo's video for probably the 15th time. And noticed where (and it all makes sense to me) that the reaction times from shock to shock have a huge play in the velocity table (duh.....) with my 70/110 file, i used values from a tractive shock which is MUCH faster than my OEM.. Doofus...)

Absolutely not stupid, no, but incorrect. The lower the number for compression and rebound - and you can even use negative numbers here, the less damping that occurs. So, all other things being equal, if you have less compression damping, the strut will compress faster. If you have less rebound damping the strut will rebound faster. Similarly, all other things being equal, to smooth things out you need to adjust compression and rebound based upon the spring rates - lower spring rates typically require more compression damping and less rebound damping. Not always, but most of the time. The larger compression damping will ensure that you do not bottom out the suspension, particularly with high speed bumps. The lower rebound damping makes sure that repeated hits will not cause a cumulative strut bottoming out effect that would occur if the strut was unable to return to its fully extended position before hitting the next bump. Decreasing the compression damping won't make the car feel stiffer unless you're bottoming out the suspension. A too low value of rebound damping will make the car feel floaty.

Yeah, the OEM dampers will definitely make the car respond very differently, and quite possibly will make it feel alternately "crashy" and "floaty". Remember also that all of the values are interrelated. It's not really possible to take some values from one file and just put them into a file for another manufacturer's shocks. The different calibration ranges are closely tied to the various damping percentages, and the difference between a 6-10ms vs 100-150ms reaction time is astounding.

Honestly not quite sure how exactly it will respond, but you can always try out 991-1-OEM-dampers-KW-HAS-44-100-v1 and see if it is a reasonable starting point. Given it's a v1 revision, it will probably need some amount of refinement.
