997GTS is N/A, so does it have the built-in accelerometer like the turbo's do?

TT Surgeon

All the AWD porsches have the accelerometer, only the RWD do not.

^^ Ahh, good to know. Learned something new..

Please allow me to elaborate:

All 997.1TT/GT2 came factory equipped with 3-axis accelerometer.
All 997.2TT/TTS/GT2RS came factory equipped with 3-axis accelerometer.
All 987.2 and 997.2(includes Carrera/S/4/4S/GTS/GT3/RS) came factory equipped with 3-axis accelerometer.

Only the 997.1 non-turbo cars and 987.1 cars from model year 2005-2008 came factory equipped with 2-axis accelerometer. These cars need to have DSC 3-axis accelerometer in order for DSC to have 3-axis g-force data for active damping control.

Hey Tom - I just installed Bilstein B8s on my 997.1 turbo. Anything need to be done to my installed DSC to optimize dampers?

Hi. Majority of times the standard DSC mapping works great with OEM PASM dampers, B4, B6, B8, and B16. The reason is DSC doesn't command the dampers to be at a specific setting at the time. DSC uses an active damping command range of 5%-100% in Normal mode, and 20%-100% in Sport model. The harder you drive the more g-force is produced, the higher g-force and rate of change triggers stiffer % damping command to the individual damper to counter the load. Since the DSC commands are active within the entire operating range of each individual damper(Front, Rear, Left, Right) this makes one well-developed map extremely versatile. Keep in mind that a 100% command to a B8 or B16 damper is a little bit stiffer than the same 100% command to the OEM PASM damper, so using the same DSC map will make the suspension firmer at peak loads. If you wish to make the ride softer at zero load then you could change the range to 1%-100% or 3%-100%. Vice versa if you want zero load to be stiffer then change the range to 30%-100%. Doing this will be shorting the width of the range but some drivers prefer it, its subjective. If you like the way your car feels then there's no need to make any changes. The standard DSC map is very-well developed, the upper load range of this exact map was developed and raced on IMSA GT3 Cup Challenge winning car.

Went to the Parts Depart at my local Porsche Dealer today. They told me the 964RS engine mounts were solid. My 997.2 Turbo has Dynamic Mounts. Why is it an advantage to go from dynamic to solid mounts, if not tracking the car? Would be stiffer all the time, but more noise all the time with some vibration as well. Bruce

Tom@TPC Racing

The 964RS engine mounts are solid in the context that they are solid rubber. As oppose to most people refer to solid as solid metal.

The dynamic mounts are a great concept but just like the PASM, the factory programmed commands for this generation of cars leaves more to be desired for a high performance driving enthusiast. Even on the 991 Turbo, 991 Turbo S, and 991 GT3 the dynamic mount commands aren't spot on. On the 991-series cars the PASM control box happens to also controls the dynamic mounts so naturally on these cars when DSC is installed the dynamic mounts are commanded by the DSC active mapping. In the 997-series cars the dynamic mounts are controlled by the ECU so there's nothing the DSC can do for that.

Anyway, if you want to get rid of some unwanted movements of the drivetrain with the car's body the 964RS is a good option. Other options are standard OEM GT2/GT3/RS mounts if you want the mounts to retain original look. The aftermarket tune-able polyurethane mounts are nice too.

What a shame! I'd Love to feel the car if TPC could control them like the 991's.

Oh well, It's still absolutely amazing for what I do (for now).

Dont really notice any additional NVH since install of RS motor mounts.

Brainz

Did you notice any difference in how the car drove/handled?

I've got a set of 964RS mounts waiting to be installed. I doubt they'll be as favorably noticeable as the DSC, but a man can hope...

Tom@TPC Racing

If it makes you feel better the 991 DSC is priced higher for the extra function.

Big Swole

Ha!! Yeah that helps a little..lol

Thanks again Tom for a great product! I LOVE driving my car even more now.

thxbuff2001

So I can use 1 DSC box for 3 cars ALL AWD 997? That would be a sweet surprise. My cars are garaged in different cities.

Got an answer from TOM, it does work on all cars.

Tom@TPC Racing

The same DSC box works great on your 2011 GT3 RS too!
