I got my ZL1 back and I might put the new box in. It’s for sale now unopened and never used but curiosity might win out. While the previous version struggled over bumps, it did make the SS I had feel much more athletic through turns.

That wouldn’t be an awful thing in the heavier ZL1, but it’s no track data or performance metric to go by.

Sweet, for my 911th post I’m writing about handling.

The major crutch the DSC controller has is it doesn't use corner ride heights in it's calculations, and it's always reactive in X and Y axes, not predictive. The DSC software doesn't account for Z-axis position or acceleration whatsoever. It can't know if the car is floating mid-jump or being compressed in a banked turn. This is why the DSC controller can never be as good as this generation of OEM MRC.

The only successes are guys that have vested interests in DSC and are auto-xing with no vertical undulations. It's a particular use case that doesn't apply to road or track.

No ups and downs in autocross? Pretty sure I autocrossed the same parking lot for a most of the season with a few dips and the car handled great loaded up(with DSC).

Did you back-to-back the OEM MRC computer to the DSC?

Yes, personally i found the OEM a little bouncy on the dips while the DSC wasn't. However later on in the year a guy with a GT350 was complaining about it not dampening well with the DSC while i wasn't having any issues.

Edit: You did mention you were an early adopter, while mine is V3 so perhaps they've made some changes.

You can't tell much about suspension tuning from AutoX.

You need triple digit speeds and a sweeping curve with a dip or broken pavement mid-corner when the suspension is loaded up to really tell how good the tuning is.

There are two very different things going on when you are talking about whether it is better or not. One is ride quality, the other (which to me is more important) is the damping curves on both compression and rebound and how quick it settles the chassis after it is upset from a dip, bump, road imperfection, etc.

What I believe DSC is doing is changing the ride quality under certain conditions, not making the damping curves any better. And by doing that, they are probably making it less stable under certain circumstances because from what I have read about them is they actually soften up some areas.

Can you explain your reasoning

Not much to explain, I think my comments are pretty self explanatory.

Well if you think suspension tuning isn't important for autocross then I suggest you put some blown out Konis are your camaro, take it to an autocross, and let me know how that goes, because shock tuning is one of the most important features on how a car handles.

One of the big changes the DSC module does is set the "0g" damper strength baseline (their so called "g comfort" parameters). Their off-the-shelf tunes put the dampers at nearly full-soft until a lateral or longitudinal g-force is observed, then the software goes to that table and adds damping resistance. There are several modifiers, but the misleading one is the Camaro software doesn't use the ride height sensors for absolute position, only to calculate damper velocity.

So, the DSC module is reactive, not proactive. If one or more tires is off the pavement, it doesn't know that. The OEM module does account for wheel position, which is why it lands jumps gracefully and the DSC cannot.

If you like the DSC though, then that's really all that matters.

Apparently you DO need an explanation.

You took my words to the extreme.

I said "Doesn't matter AS MUCH"

You interpreted as "Doesn't matter AT ALL"

I just put a set of DSSV’s in my SS1LE. Mainly for tire clearance and camber wear, and hopes of increased performance. I got a great deal on them, and my car rarely sees street time. Hoping they compliment my DH’s and NT01’s. I’ll report back with lap time deltas on my home track.

Thats interesting and i wasn't aware of it not using that. However, you can adjust the high med and low speed velocities on compression and rebound now through the tuning software. Was that not around when you were using the module earlier on? Also i just want to point that i appreciate all the work you did on the suspension part number mega thread!

It was mostly just sarcasm, because you're wrong in your statement. Shock tuning is important in all aspects of driving i.e.. street, autocross, and track. Now if you wanna say something that doesn't matter as much it would be street driving, but there is no way autocross doesn't matter as much as track.

That guy doesn't track or auto-x his car, yet he likes to act like he is a suspension expert because he paid way too much money to put in solid rear cradle mounts when he only drives on the street.

travislambert: Can we get an update on your thoughts on the DSSV swap given you’ve probably had some more track time since your last post about it. Thanks.
