the concern over a default setting in case of failure is the same as OE if there is a failure to the system all four corners are treated equally. We addressed that in 2008 when we developed the first Porsche controller.
as far as wear and tear to the damper it may be less stressful to the shock than original as the frequency is different and we run a dither to help change the current direction and or control where the original relies on a check valve to unload mechanically

I'm sure your part works, and I'm sure you've done your homework. But from a liability and insurance concern the risk to me is too large.
If this was a modification of a calibration for the existing SW you'd still have all the fail safes built into the stock code, and you'd have the durability testing of the stock module.
Right now, you don't have any of that, and since this is an underbody module which is exposed to the elements the risk is much higher than say, putting in an aftermarket radio.

I had the update done last week. I haven't been on a track yet but I have a nice twisty mountain road on the way to work everyday. Tour mode is very different. The ride over rough road is much improved.
Car definitely settles quicker after uneven spot.The handling is hard to judge as it already does pretty good. I also have brand new tires.

I just had the update done on my C7 Z06.
Gotta say, there is a noticeable amount of difference.
Tour mode suspension is a LOT comfier. Track is a little bit more stiffer I think.
But definitely touring suspension got less stiff and more comfy.
Totally worth the $350!

I'm talking about a durability of your hardware, testing of your software (I'm betting you're not ASPICE certified or use ISO 26262 Functional Safety), and other "automotive grade" requirements.
I'm sure your part works, and I'm sure you've done your homework. But from a liability and insurance concern the risk to me is too large.
If this was a modification of a calibration for the existing SW you'd still have all the fail safes built into the stock code, and you'd have the durability testing of the stock module.

You can quote all the durability tests you want. Based on all that great durability testing GM did on the overheating C7 Z06's, I doubt their product is any better (or even as durable, based on where it was probably built by the lowest bidder) as the DSC product. You've made your point, give it rest.
I will try the GM upgrade first if they ever get it released in the foreseeable future (17 GS), but if not, I'd have no issues going with the DSC....but if I can save $850 and get an acceptable, similar result, even better.
I'm about to drop several grand on some custom forged wheels. Oh no! Wait!!! HRE probably hasn't done all that great durability testing GM surely has done on their stock GS wheels....you know....the ones that bend like a Cirque du Soleil contortionist.
No doubt you have a quite bit of insider knowledge to share, but your arrogant attitude indicates you may have some other agenda, leaving your input worthless.
Just like Fredo.

Further, I take a similar stance on wheels. However there are standards those vendors can follow (such as TUV verification). Some vendors like BBS do follow them.
Get over your dislike of me and have a meaningful conversation.

Your trivialization of my comments through ridiculous hyperbole is unwarranted. Electronic and mechanical components are different regardless. So your comparison is invalid.

I do not dislike you. I don’t even know you. You may be the coolest guy in the planet or a child molester. This is the Internet and I have no way of knowing that. However the character you have a created on this forum is a complete douche bag.

This is an upgrade."

Brother, I'm the same way. I use Touring when my wife is in the car. Even though I don't feel the difference, hopefully she does!
Our roads here in Kansas City are OK....not great, not terrible. I think if my Sport mode felt a lot stiffer, I wouldn't do the update. When I first bought the car, I actually took my sales person out for a ride after a month to insure the modes were actually changing.

Do you still have the OEM tires or have you moved away from the run flats? As I recall you have some beautiful aftermarket wheels and I was wondering if you had change the tires. That might make the perception of a difference between tour and sport less obvious.

Or you could choose to not be obnoxious. All good information is valued but if it comes with arrogance and condescension you lose credibility and find yourself deflecting a few snarky barbs. It doesn’t take any extra effort to be civil, but that may not be in your nature.
Either way, no hard feelings here. This is just a forum and getting good information is the key. Sometimes you just have to wade through the crap.
Getting back on track, does anyone know if the upgrade for the 2017 GS is now available?[/left]

INSTALLATION!!!!
The "PURCHASE" of the flash update costs $350...
See there is a difference....
One is the INSTALLATION or DOWNLOAD which the dealer charges back to GM, so its FREE for the LABOR FOR THEM TO INSTALL...
BUT the consumer has to PAY or BUY this performance update!
The dealer is basically installing a "part" you purchased...
"Free INSTALLATION with PURCHASE.."
Get it??
Think of it this way.. for your computer there is a new program that just came out, Windows 100, available only thru Microsoft dealers... Your dealer or computer guru will install it into your computer for FREE, BUT, YOU have to BUY the program from him!
SAME THING!
GM will re-imburse your dealer for his time to upload the flash update, but you need to BUY the program itself from him first!
So there is NO COST FOR DEALER INSTALLATION.
but there IS COST to "BUY" the program!

HE SAID THAT THE COST TO INSTALL THE UPGRADE IS $150 + $350 from GM. Is this correct?

NO, that is not correct. The $350 includes the labor to install. The dealer will be given a special code to charge for the install. It should be in the instructions they download with the update/upgrade.

Read all of the posts. No its not correct.
The $350 includes the update and installation labor.
