DSC Sport

Thank you! It was a great weekend for us!

We are running the DSC/Tractive system on our #36 GT3 Cup Car running in the Gold class (Platinum does not allow us to run the system yet, as shocks are still sealed).

We would absolutely sell the system to other teams. If someone is going to beat us, it might as well be with our own product! That's the best kind of competition from our perspective.

Just some input for the group

I have Tractive DDA shocks and run DSC Module with the newer firmware

Just back from a road trip where another driver in a similar car running OEM PASM system constantly reported bottoming out mine felt planted the entire time

The new firmware (2 modes rather than 3) must have a significantly broader dynamic range. Many of the roads we traveled were rough and bumpy. I initially I could not quite work out what was going on as the feel was significantly different from PASM but after a while I realised the system response time was constantly keeping the contact patches in play and the car felt more "alive" for want of a better word.

It never put a foot wrong, corners where some understeer, due to washboard pavement, could previously have been expected did not upset the car at all.

I now have new limits to explore

For mine, this is a great system

Thanks to Mike and Tom for their assistance in getting this set up for me.

Thank you very much for sharing your experience. We are honored that you like the new firmware. The new 2-mode firmware have what we named "Revers G Table" to keep the car planted and compliant at lower g loads. The g values to trigger any change is user tune-able should the user have different criteria than us. The Reverse G Table is truly revolutionary. The transition to higher g loads to completely seamless. After driving the DSC and Tractive DDA combinations, it makes everything else that I road test at the shop for routine work feel obsolete. With such suspension technology available and the support for it, it brings me back to the time when tune-able electronic fuel injection was replacing carburetors. Gotta love the power of modern electronics.

Apologies if this has been covered in the thread somewhere but i have read through and not seen it. I have aquired a used unit which is the three mode version. For some reason i cant get back into mode 1 unless the car is stationary, is this the way it should be? On the move i can go from 1 to 2 to 3 but subsequent prods of the button just cycles between 2 and 3. Car is a '10 RS.

Second question is about the two mode firmware? I get the bit where it's working more OEM like regards the dash indications but are the actual programs any different on improved because of this? I actually think having three modes is preferable for my uses.

Many thanks

Hi Tom, do you recommend any further changes to the TPC default tables if we have swaybars (assuming they're already adjusted to balance front/rear balance). I'm guessing that lateral g's would need less dampener stiffening, since the swaybars are already resisting chassis roll...

Tom@TPC Racing

I have never heard of this issue before. If this issue didn't occur on the previous car, then I'd recommend unplugging the unit, visually inspect the connector pins, then leave the unit unplugged for few hours(to clear the buffer) then install the unit again(make sure ignition key is out).


1) The 2-mode firmware is much more refined in its operation; like the difference between iphone 4 and iphone 6.
2) Current DSC Tuning Software doesn't support older 3-mode firmware for 997. So if you prefer 3-mode you have to like it as is, since tuning custom tuning isn't currently supported for this version.
3) The 2-mode firmware has a feature called Reverse G Table. Within a user defined range of g force and within is user defined rate of g force change, the use can define a default damping % for comfort. For example, you can make the damping resistance to be only 1% when g force is under 0.3g and with less than 20% g rate change for comfort. But if you exceed 0.3g and/or exceed the 20% rate of change the system will command with the values that are in the "normal" G Table. This is truly revolutionary next-gen supercars technology that you can have today!

I think any one with 3-mode should take advantage of our free upgrade to 2-mode while the offer stands. I am not pushing this to make money since we actually don't 'cause we do it for free. If anything its more work for us. It is a truly better product that we want DSC users to experience. For upgrade, the unit must be sent to our shop. Senders pays shipping cost.

Tom@TPC Racing

I would not make any adjustment until you drive the car and experience a characteristic you want to change since drivers have different driving styles, different drivers take different lines for a given turn that changes the response of the car, and their are unknown variables to us like the grip of the tires/brakes on the car, etc. Please remember that with DSC we are not doing "static" damper tuning, instead DSC is dynamic damper tuning mainly via g force. So if you have sway bars or tires or other items that increases lateral g then DSC will command the dampers with the values for the increased g. On the opposite end of the spectrum, if you're driving on wet track DSC will dynamically reduce the damping values for the reduced g of the wet grip condition.

Free?

Hmm.

Will the car run without any box installed? I do not have the stock unit (purchased car used with DSC already installed). Something big blew up in the car at the track yesterday (motor or trans, not sure yet... big THUD followed by silence) so it's gonna be down for a while. I can pull the box and ship it down to you guys for an upgrade BUT I don't want to make the car inoperable at the shop if/when they find time to dig into what broke.

Larry Cable

it will throw a PASM malfunction code, and PASM will not be functional, it will
be operable, but not for anything more than maneuvering it around the shop,
i.e no road/track driving would be recommended...

fedex it overnight to TPC, you'll have it back in a flash (pun intended)

User 52121

Awesome.

I might find myself down at the shop on Saturday. If I do, I'll try to pull it while I'm down there.

Larry Cable

what I dont know is if the PASM fault will clear when you reinstall or if you will need to externally clear the fault codes with PIWIS/Durametric.

nwGTS

I'd imagine with a blown engine they'll be a few more faults than PASM to worry about.

User 52121

That's fine. I have a Durametric and they have PIWIS.

Tom@TPC Racing

Plugging DSC module from the harness connector will cause the instrument to display "PASM Fault". The shocks will default to full stiff with no module plugged into the connector. It is okay to move the car around in a shop or in a parking lot without a module plugged in. I have even dyno tested and driven short distance trips without a module plugged in. But don't do any track events or autoX or drive aggressively without a module plugged in because full stiff shocks make the car handle badly!

The PASM Fault message will clear for the next key on/off cycle after module is plugged in.
