Guys, I'm still reading through the 61 pages (halfway done), but I'm wondering two things:
1. How many of you have installed the DSC controller on an FE2 car (base + MSRC)?
2. Does anyone know if the spring rates between the base and Z51 cars are the same given this recently released spring rate chart? I understand that Mike's controller files apply across the board, whether it's a base +MSRC, Z51, Z06, or Z07, but I was still curious. I'm having a hard time dechipering what the 2nd set of numbers signify in cells 3 and 4 of column 3, 4, 5.
those numbers are for the z51+msrc, grand sport+ z07 package, z06 + z07 package.

another vote for DSC - i'm in love with it.
i'm tuning it myself and after ~30 tunes it's perfect (as much as perfect can be )
BTW - i eventually did a digressive tune on the shocks table.
The spring rate is not the factory it's controlling the damper I personally love softer chassis with damper control remember this is velocity amd load based the shock range is huge
Don't get hung up on what spring your running
Ok, I was just curious. Curiosity killed the cat, I suppose.
Better late than never; I put the DSC module on this weekend and took my 17 Grand sport out. No problems at all and it feels just like you guys have said. Instead of riding on top of the pavement, it feels like you are more melted into it. Does that sound about right? Just feels awesome and it does take the harshness out of the ride but feels more planted.
I was also struck by what Mike said just above, and I hadn't really thought about it before, but I think that people do get hung up on spring rates, and don't appreciate the significance of shocks that can be adjusted in milliseconds based upon the data the car is delivering to a very sophisticated control device.
The OEM controller is very primitive in terms of taking advantage of that capability. The DSC controller does such a good job of predicting how the dampers should be set given what the car is doing that spring rate becomes much less relevant. It's been said many times in this thread, but the DSC controller is far more predictive, whereas the OEM is more reactive.
I have one of these on the way - any installation, startup, programming tips? This will be installed on my daily driver 2014 s/c'ed Z51 M7 on the rough California roads (rated 49th in the nation for the 50 % of roads in disrepair). Tires are 255/305 MPSS non-runflat. Is the default programming best for my application?

Stay with default, they have done a lot more. Testing than us and pretty much have it dialed in.
Update to the 8-28 firmware and make sure then to load the 8-31 settings (they are a seperate download at the site!) that were designed for the new firmware. After that's done, make sure to 0 the travel with you sitting in the car with a laptop. That's it!
FYI - I got this email from DSC (TPC Racing) today. I opted to wait for the new version.
"This message is to make you aware that there has been a processor update to the Corvette C7 controller that you have ordered from us. The updated processor is faster and will also eliminate any Service Suspension faults. We see that you have placed an order with us, but we do recommend that you wait for the new batch of controllers with the better processor because you will be happier with the way that it works. We do have some controllers in stock with the old processor and they are available to ship now. You can let us know if you would like the older version and we can ship.
The lead time on the new controllers is 3 to 4 weeks. Please let us know if you have any questions or concerns."
Interesting! I wonder if you ordered recently if you can exchange for the faster processor device. I just checked their site and it is listed as out of stock.

I could be wrong, but as I understand it, there was a recent run of controllers that had a different processor, which didn't function as well as ones they were using earlier. The older units like the one I had installed almost a year ago have been trouble-free.
Sounds to me as if the processor they switched to in the problematic batch was slower than what they were previously using.

I was about to return mine due to the service suspension alert and multiple attempts re-installing the board. I was very frustrated at times but the assurance by DSC that they stand behind their product kept me going. DSC offered a full refund and sent me a return label. I was handing my issues by email, and I decided instead to call and speak to Tom. It was a great call that I then decided to keep my board and wait for the new one.
TPC Racing/DSC Sport is a great company made up of really good folks. I'm certain they had no idea that there was any problem, or anything different, with the recent batch of controllers, or processor until it sporadically popped up here.
It sounds like Mike and his team have now located the source of the problem. They will make it right.
I'm headed over there this morning. I'll encourage them to share additional info here, because I'm sure this recent revelation will have others asking questions.
Any way to find out if I have the”less than optimum “ controller?
Depends on when you bought and how long you've been using it.
If you've had it for over 2 -3 months and not getting "Service Suspension" warnings, you're good
Just back from DSC, and I had a long talk with Mike Levitas. As I suspected, the issue with latest batch of controllers was not a processor speed issue at all, but a manufacturing problem. In fact, it wasn't a processor issue at all.
He said he would post a full explanation here sometime today, but suffice it to say, the recent rash of service suspension warnings has been fully diagnosed and corrected. If you're not having the problem, your controller is the "latest and greatest" speed-wise, no matter when you purchased it, and you're good to go. Mike said a faster processor is not necessary on the C7.
Moreover, the vast majority of the "problem batch" are not defective, so if you have one of those, and are not getting the suspension warning, you're fine.
Lest anyone have any doubts about the capabilities of TPC Racing/DSC Sport, the picture below speaks for itself. This is just one of many shelves of awards won by cars built in their shop and driven by Mike and his team. Note the 2006 Rolex 24 Hrs of Daytona framed championship poster behind the trophies. The winning car pictured in that poster is retired and sitting in his lobby.
Thanks, Foosh. I wasn't having problems but was concerned that resale may be affected since people would probably ask if I had the updated controller or not at time of sale.
Glad to see it's more about defective units. I wonder why processor speed got mentioned then?
We talked about that, and I'll leave that to Mike/DSC team to explain, but the most important takeaway is that increased processor speed isn't going to do anything for the current C7, and that wasn't the cause of the problem anyway.
so, I get the suspension error every now and then. What is causing this? Seems like when it happens I loose suspension for a fraction of a second, car gets strange. Also, when this happens do I need to re-zero settings?

It's possible that you are running into the defect issue, contact Dsc.
