Very interesting. I agree that TPC is a first-rate tuner with quite capable professional test driver. I trust what they do. Surprisingly, they are the only people who have deciphered the programming of the PASM. Maybe not too surprising I guess as I could imagine how complicated the algorithm is; clearly they have an in-house expert (who?). Kudos to TPC.

For the fun of discussing, some speculations:
1. I would assume this programming change the damping of the stock Turbo's damper. 997.1 Turbo has a design flaw in PASM: Normal is too soft (say 1 out of scale of 10) and Sport is too hard (say 8-9 out of 10) giving the car a Jekyll and Hyde personality, way too soft or way too jittery; I would imagine TPC resets the damper say at 6 and go from there. Pure speculating.
2. The stock PASM *is* also an active unit. TPC didn't make it active; what they did is make it more usable.
3. I would imagine this program is spring/coilover specific; it would work best with whatever TPC has used to test it with. In this case, sounds like the OP's car? If you install the program on a stiffer spring, says Techart, it probably would adapt to work, but probably is not ideal, and might be too stiff (again, speculating for fun). Each damping program works best for a certain spring setup, I would think.
4. Note that this mod doesn't lower the car - which is desirable for both esthetic and dynamic (lowered center of gravity) reasons. Essentially it approaches suspension tuning from the "other" side: adjusting the damper, instead of adjusting the spring (such as lowering spring, coilover, etc.). It would be fascinating to test track times of OP's car versus a car with Bilstein, particularly the Bilstein modded by TPC, which in my opinion might be the best available for the Turbo.
5. For those who don't want to touch the suspension physical setup, this is a great, great way to improve the Turbo's single greatest Achilles' heel: its soft *** suspension system. IMHO of course and pending further testing by others, and price dependent. I hope it wouldn't cost more than say, changing to lowering spring.

Questions for OP please:
1. What is on your car? Stock suspension?
2. During that track testing, what mode did TPC set it on: Normal or Sport?
A. How is the Normal mode different from before? Stiffer or softer, etc.?
B. How is the Sport mode different from before? Stiffer or softer?
C. With the TPC module, do you still use Normal for street, Sport for track? Or do you just leave it on one mode?

 

Please provide more info, as I'm in the market for suspension upgrades.

Ballpark cost? Is this a $500 or $5000 item?

 

Whatever happened to this product? Did it get released?

 

Subscribed!

 

Subscribed...

 

I thought you were leaving this one alone

 

i have been checking this thread like i am an addict !
i love learning and reading about this stuff.
can we get more info ? anything ? is it safe to assume this is probably optimized for pss10s ?

 

Interesting... Wonder if this will work with existing suspension mods(GMG springs & Sways) ?

 

I am, just an interesting topic.

 

I'm kind of surprised that nobody from TPC has chimed in on this thread. They're a very reputable Tuner with the Racing pedigree to go with their street cred dating back pre-993. So they obviously know something about suspension tuning in addition to engine tuning/management. In racing, suspension advantages are everything, so this is a very interesting subject. I'd love to hear more about it! TPC, can you guys comment and give some insight? I think Cannga has a very good hypothesis as to how this works. But that being said, who knows, could be entirely different all together, I'd love to hear straight from the horses mouth on this one. TPC, not that I'm calling you guys horses, well maybe thoroughbreds, that wouldn't be so bad would it? :lol:

 

I have heard from TPC that the release date on this product is mid Feb. Won't be long I guess.

 

I'd love to get more info on this!

 

Hi Scott, thanks for the history; I didn't know TPC go back that far and agreed that they are a first rate AND very talented tuner (no one else has cracked the PASM code that I know of). I love how they prolong the "suspension" pun intended :-). Regarding this mod, I believe I am quite "warm," might even be pretty "hot" LOL with my guess.

Not for Scott but for poster who asked if it works for PSS10, my guess is no, this only works on systems with PASM, in other words, Bilstein B16 Damptronic (the one that's PASM compatible) yes, Bilstein B16 PSS10 (the one with manual setting of dampening forces) no. Think of it this way, when you modify the suspension, you could change either the A. Spring, or B. Damper, or C. Both, and combinations of these 3 is how systems currently available work:

1. Modify the Damper programming (TPC approach here)
2. Modify the Springs (lowering springs)
3. Change the Damper and Springs with coilover (Bilstein B16 Damptronic)
4. Modify the Bilstein Damper programming and Springs further (TPC version of Bilstein Damptronic)

The reason number 1 works is that the stock damper programming of first generation 997.1 Turbo is flawed. The Normal setting is excessively soft (under damped) and the Sport setting is excessively stiff (over damped, jittery, un-useable). Number 2 (lowering springs) above still has to deal with the flawed PASM 1. Number 3 Bilstein Damptronic and 997.2 Turbo remove the Jekyll and Hide character of the damper programming, and now TPC I would guess. (BTW, Porsche engineers acknowledged this flaw with PASM 1 when they released 997.2.)

 

any news on this product?

 

Interested as well!
