Thought I would chime in on this with some more feedback.

Short version - purchased, installed in 5 minutes before my commute to work, really enjoying it ($ well spent for me).

Long version - Maybe I'm getting soft, but the stock suspension settings were way to stiff for our Bay Area roads and I wasn't as comfortable as I wanted to be daily driving my new to me 997 turbo. Years of road racing (and crashing) liter bikes has left my body battered. Also, in "sport" mode the thing was way off for all but the smoothest of roads (damn her scary IMO). If i had to guess (I'm certainly no expert) there was way too much high speed compression dampening at the top of the stroke and high speed rebound was pretty slow in the front making it feel like the tires would loose contact with the road hitting and going over a bump, or traversing a fast dip. The rear probably didn't have enough low speed compression (too much squat) and was off as well IMO.

Night and day difference with the TPC module installed. Standard setting is much more livable. Setting 3 feels somewhere in between "normal" and "sport" with the stock box. Setting 2 is in between but haven't driven enough to discern all the nuances. Overall the car definitely pitches less in all directions and is much more usable/drivable. I haven't had a chance to test in more aggressive situations and likely won't track this car (have a track car), but overall very satisfied. Just reinforcing my desire to keep the car mostly stock (except for maybe GT3 control arms and Europipe).

A suggestion for TPC: Please make the light off in standard setting, solid in setting 2, and flashing in setting 3. If this is possible I would really like to send my box back for this minor change.

 

Very glad that you are enjoying the DSC system! In regards to the light, this is something that we may change down the road and will let everyone know if and when that is available.

GTRNICK explained the Sport and PASM button functions very well! With DSC, the two buttons no longer affect each other anymore. The Sport button still functions as normal but the PASM is now always on with DSC.

 

A brain fart move but good example of setting 1 and 3. I had been daily driving and had it in setting 1. Then went to a track at Thompson. First session was a freakin mess, even put 2 wheels off (first time ever) and car was floating down the front straight, couldn't hammer into corners without sliding. I had been there a month earlier and didn't have any issues. Ended session pissed and then looked down, Fn' A, I had left it in soft mode. So I could argue the light/blinking needs to be more prominent.

Rest of day put it back into setting 3 and was back to being one of the fastest in the run group (black). It's such a night and day difference, even with street tires this day (Yokohama AD08Rs) I was close to the times on my R6s a month earlier.

 

Now that I've had mine installed for a month or so.... I have some questions for Harris/TPC.

If I had input on the modes, I'd want mode 3 to be stiffer. Is this possible? I don't feel any difference between mode 2 and mode 3 on the street and feel mode 3 should be stiffer for track duty.

I typically leave it in mode 1 for daily commuting. I'll switch it to mode 3 for the times when I know I am going to be driving it harder and even on the street find myself wishing mode 3 was firmer.

So for me, 1 is fine, 2 should be what 3 is and 3 should be as stiff as possible without harming components or going past what's safe for the shock and/or whatever keeps the car from going back to the po-go like factory settings.

 

Please email me and we can discuss custom mapping. Down the road once we do a full product launch, there will be a user friendly software so that you can customize your DSC program and have the ability to share that file as well to other DSC owners.

 

this sounds awesome. how far away is the end user software?

 

Done!

 

A great product just got a whole lot better

 

The proof of a good product is that users are already discussing how to improve it because they like it so much. I easily installed the DSC on my 2008 TT a couple of weeks ago using instructions from this forum. My car is stock except for sway bars and drop links but the DSC is such an improvement to the suspension it seems like magic.

 

Very glad to hear that you are enjoying the DSC in your TT!

 

Hi,

wondering whether the Group Buy for the DSC ever materialized? I would definitely be interested.

Thanks

Go back a few pages..... It never happened. I got tired of waiting and just bought mine. Don't regret it for a second. Just buy it.

 

The minimal discount from a group buy vs the time lost driving without this makes it a no brainier. Buy one as soon as you can.

 

I would just call Tom or Harris at TPC. they extended to me the group buy forum pricing from the Planet-9 group buy. Maybe they'll do same for you, or maybe the discounted introductory period is over and they've achieved their goal - getting a few out to forum members like myself, who could get the word out about how great it is so people would start buying them in larger quantities at the regular price.

 

Me too?
