any owners installed the DSCv3 Controller with the OEM shocks? do we have opinions? I'd love to hear them. I am particularly interested in any before and after impressions and specifically for the GT3.

Hard to improve on this setup, but if possible I'd order in a second.

+1 Ive had DSC on my 7.2 GT3 and on my 991.1 GTS ... def an improvement over OEM PASM controller ...

daveo4porsche

bump - are there any GT3 991.1 or 991.2 that can speak to this upgrade?

Larry Cable

here's the thing - its programmable, so if you dont like the way your suspension is performing (with the OTS map), you can re-program it to do so ... Tom & Mike @ TPC are very helpful in that regard ...

Also since its 'algorithmic' it can do smart things like increase the resistance on the 'outside' shocks in a corner or on the fronts, when braking, to dial out roll or dive ... its a no brainer better solution than OEM ...

I use it on my 991.2 GT3.

Works very well. I also had it on my 991.1 GT3.

Added bonus is that the car is more compliant around town.

PM me with any specific questions.

using the off the shelf 991 maps?

daveo4porsche

does it come with decent and default "maps"? or does it need some configuration after install?

daveo4porsche

oh and thank you @sasportas - your feedback and others is moving this item on to my modification list - I'm excited…

It hasn't been out long enough for good maps for the .2 apparently they found out that for the .1 there was a delay built into the software before the PASM would react. I have the .1 DSC Controller and would be glad to sell it (DSC2). It really should not be used on the .2 I kept it on, kept on switching PASM computers but finally decided on the DSC.

Thanks for the inputs.
I wanted to clarify some things:

1) If you have a DSC controller that was config'ed for 991.1 you should absolutely not be installing it on a 991.2 !!! Unless the controller is sent in to be converted for use on 991.2.

2) The DSC standard mapping is very good. Can it be tuned better for a particular track for a specific driver's personal preference? Yes, of course, this is true for any adjustable suspension item.

3) The "delay" described in above post is the DSC Velocity tuning function. The DSC Velocity tuning function uses the factory ride height sensor data to tune individual damper for hi-speed, med-speed, and low-speed Compression and Rebound in near real time. The "delay" is actually not caused by the DSC, it is the ride height sensor data being filtered by the factory system before the data is broadcast to the CAN-bus. The CAN-bus is basically the factory information highway system which contains data such as vehicle speed, g-force, steering angle, brake line pressure, ride height sensor, engine rpm, engine temp, and more. For example, if you add a AIM Smartycam or MoTec or RaceLogic VBox to make videos that displays data then you would connect the video equipment to the CAN-bus to collect the desired data. DSC uses the data on the CAN-bus for tuning the suspension. When DSC V2(version 2) was made, we do not expected that the ride height sensor data was filtered before it was broadcast. No other car company that DSC supports did that. The delay is a fraction of a second for the ride sensor data. All other data is live. DSC currently offers V3(version 3), that has different hardware to captures raw ride height sensor data for more accurate Velocity function. Keep in mind that ultimately the limitation reaction time is limited by the factory shocks which is around ~100 millisecond. Not all cars have ride height sensors, DSC uses 3-axis g-force, brake line pressure, and throttle position as primary tuning data. Velocity is a bonus feature for cars equipped with ride height sensors such as all Porsche 991/981. DSC V3 controller is available for 991.1 and 991.2.

Can these still be installed with a roll bar or would I have to take the roll bar out?

Tom@TPC Racing

It can be installed with roll bar. It helps to have thin long arms or remove one seat for the install. I usually leave a mini-USB cable attached to the DSC to make it easier to do any tuning or data logging.

drdonger

Thanks, it looks like I'd definitely need to take a seat out to do it.

Tom@TPC Racing

Welcome. I did an installation for a guy at the track, the car had roll bar and rigid seats. It took me like 20 minutes for the install. In hindsight it would have been closer to 10 minutes had I remove the passenger seat, and less painful for my arms.
