DSC pasm box on a 997.1 Gt3

[evodarren]

Anybody fitted a DSC box ans Accelerometer the a Gt3 or 911.
Tempted to hopefully control the ride a bit better. Make it more compliant on some of our Roads.

Feast your minces on this.

In short, virtually everybody who tried TPC's DSC thought the mod was thoroughly worth it. To the point that they couldn't understand why Porsche didn't just buy the company.

No, but I intend to. I have one and had it fitted to my 997.2 T4S - it did transform it.
They told me at the time that I could flash the firmware to 997.1 GT3 but that I would also require their additional accelerometer module because the 997.1 GT3 doesn't have one.

Ohlins R&T are only twice the price, so it seems daft to use DSC on some old nackered shocks imo.

Why even spend money on ohlins when you have tractive?

Both my front shocks were rebuilt by Bilstein last week up at CG, because of DU bush creak on near side. So all my shock are working to spec now. Don’t do any track days so not interested in changing shocks are I don’t think I would get the full benifit on the road.

Why go for DSC then?

Hopefully 11 year advance in software will give them more control; as the DSc unit acts 16 x faster and each shock is independently controlled separately not like the standard PASM

if you buy more parts, still rather have a new set of shocks with 2 way adjustment.

I can see why this is a good option for a lot of Gt3 owners. The blistein refurb is buttons and it allows the car to be improved without a fundamental change away from standard.

I am very interested in fitting the system to my 997 Gen 1 - but only if i can map it to my own requirements

you can but it's complex and the support web site never came up with the goods to teach you.
imo turning a bump/rebound knob 2 clicks is far easier :-)

I guess if you knew DSC inside out then it could be worth it, but you still have a set of 10 year old shocks on a car which are low rent vs new kit.
Ohlins R&T seems too good a value to mess about with DSC boxes and 3rd party accermeters etc

they started to do you tube lessons 2 years a go but that did not happen in the end so it's a non starter for me if it's too hard to learn and use.

it's like they made it then forgot all about it ?

seems a nice idea on the newer GT4 and GT3 models as it's plug and play on a new car , but on older cars just buy some shocks imo you would be faster.

atm it needs user software with sliders, so if you want it to damp more you move a slider for slow rebound etc.

it's a shame they did not do the lessons on the DSC website

I would say a full shock rebuild, DSC and the extra accelerometers would cost more than a set of Ohlins though

I do understand you point.

My car is only used for fast road blasts not track days .lots of European road trips planned with the wife. Cant stop off all the time adjusting the shocks. .Hopefully this should improve the ride quality on our trips on some of the bad roads. Plus my car is still under OPC warranty. The DSC box can be changed out quickly if I have to take my car in.

it's an option of course , it's just very flawed imo.

Hence why on new cars like the GT4 and GT3 it's a easier choice to make due to warranty but on older cars it seems a daft one to make.

you would not have to adjust the shocks if you don't track, just set them up once and forget and least you can dial In the car to drive how you want it on some plush new shocks.

I see your point about the IT support. That would be a concern. Not sure about the cost of passives though. If I were to upgrade, i'd be looking at something high end like JRZ, Moton etc.. so your cost estimate would be well out there. Thats why a plug and play option still has an attraction. A refurb of the standard damper would not be money badly spent and if you decide to sell the DSC untit it would be easy to sell and recover the majority of the cost.

I think the DSC unit would still be my starting point.

Darren I'm a big fan of the DSC unit and had it on my 997GTS and my 991GT3.

The fact it updates 16 times faster though isn't a great benefit when you look at it as the standard shocks aren't capable of receiving the commands at the higher refresh rate. I think some of Bilstein's aftermarket Damptronic units do.

I would definitely recommend getting one. As for the software it depends, I have 30 years in IT and its easy enough to work out but I wouldn't call it user friendly.

Fred

Hi Fred

Thank you for the insight. Having my 3 axis Accelerometer and DSC fitted Saturday. I hope I can feel the difference. If I don't feel like it works I am being offered to return and get my money back, minus the fitting charge.
As I only use my on the road, I can only see that it will be an improvement.

Regards
Darren

To be honest the software isn't that difficult to use. Given you want it for road use the primary usage will be to soften the 'comfort' ratio and that's easy as chips. After messing around with it a bit more on my car (7.2rs) I do think it's a definite improvement from being a bit indifferent to it earlier.

The ride when I'm just trying to get from a to b is better, when driving quickly on the road it deals with bumps in a more controlled way and especially stops porpoising around on uneven surfaces and when on track the car is definitely more stable on fast direction changes. Obviously going to high end dampers (not merely Ohlins R/T but TTX and similar) would be better but you then need to find someone who knows what he's doing to set up the thing properly so I'd say the dsc is a decent compromise especially since you have refreshed your oem dampers.

Hi Darren - do you know where the accelerometer is fitted? Is it hidden away with the DSC PASM module under the glovebox? Thanks Paul

Hi Windy

I believe it is fitted on the passenger side centre console in the footwell.
I will be able to confirm this on Saturday.

I wasn't intending to replace damper or go for the DSC, but had creaking diagnosed by Chris at CG. He got the dampers rebuilt and all is great again. He also mentioned the DSC box which I stated looking into. Im off to the South of France and Italy in June. The first time this car has left UK soil. And I have had this car for 5 1/2 years (Shameful, I know) the wife is coming and we plan on doing lots more trips. My first intention was to improve the ride comfort/quality on the not so good roads.purely on the longer trips to make it less weary. I don't care too much when im out for a quick hour blast. I did try a 991 Turbo the other day as a change of car, but the steering feel, gearchange and general feel of my GT3 still gave me more emotion. For me its not all about hitting 0-60 in sub 3 seconds.

Sorry bit of a long winded reply.
