Anyone running a DSC Sport V2 PASM controller on a 981?

[Twinfan]

There seems to be plenty of info on the web regarding 9x7s running DSC Sport's replacement PASM controller but not so much on 981 models. I'm considering one for my CGTS and was wondering if anyone had any experience they could share before I shell out £1400.

Any info much appreciated!

Speak to Chris Franklin, he has a number of clients running them. I've had mine installed for a year and have posted reflections on PCGB forum and 911uk.

Why would you?

What does it do?

Said to have a better algorithm than porsche one and have a better ride handling combination in the two modes. Perfectly plausible on the 987, but a harder act on the 981

I would say other way round, better on the 981 platform as it takes more YAW data

but it's really for a trackcar to help tyre wear and dive under brakes, not sure it's any use on a 981 road only car imo for the money.

It's not really a better algorithm, the DSC allows the shock to use more than PASM allows say normal is 20-60 % and Sport is 60-90%

DSC allows 10-100% all the time.

It's not easy to use, unlike a knob on a shock you can turn 1 click for bump, DSC has confusing tables to map out, one will never get it right imo as the map is a generic 991 911 map ! I have heard a lot of poor reviews as well as good ones, but the good ones seem to come from track use as I have said to help firm up the shock under extreme brakes and cornering.

This is what I'm thinking. A worthwhile addition on a 9x7 given the fact that Sport is generally seen as too hard, but on a 9x1 PASM is very good anyway so it would be less of an improvement on a standard car (if any).

thing is you cannot polish a turd, 1.4k for a DSC on a st system in the 987 or £1.8k on some ohlins road and track shocks .

On the GT4 it's worh it as you cannot buy road and track shocks, only the txx £5k units so if you track the GT4 then I would say buy a DSC, but that's about it.

it's been out a while they keep saying they will post how to program it, but to date zero support on how to use the dam thing.

Ohlins R&T are not active though are they, not everyone wants to replace their active system with a passive one. Nor do they want full track biased suspension.

The whole PASM unit is independent and replaced, so in theory the st 987 unit is replaced with the good DSC controller.

no one presses PASM on the 987 cars even on the 981 it's pretty much unusable. the poor units are the shocks as I said you cannot polish a turd.

road and track is just that road !! which work on track if you turn some knobs, you have rebound adjustment , the ride will be better with ohlins and if you want it soft you click a knob 1 click and leave it.

none of this is track bias they run spring rates 3x the amount and trailer the cars. the after market spring road spring rates is normally 50% stiffer but on plush expensive dampers.

The new breed of cars are amazing for ride due to helper springs, my GT4 ride is shocking good, again I have never pressed the PASM button.

The 981 PASM is not unusable - I use Sport all the time, only switching to Standard on the motorway if the surface is bad. Ride quality is excellent. I was just wondering if the DSC controller would make it even better.

If you want unusable, try a Focus RS mk3 in the Sport chassis setting...

we will have to agree to disagree then as I find PASM unusable and drive my mates 981 now and again.
DSC is not magic it can only work with what you have, It just allows the full range of the damping 100% of the time, when Porsche use % rates.

I doubt you would ever tweak it as no one is making maps so you are stuck with a 991 rear engine map on a Boxster, unless you have a lap top and want to spend 100 hours making a map !

C of G have plans to do maps, but it's time consuming and expensive for little gain for the dealer.

I wanted one for the GT4 but it's too hard to retune imo atm.

[Twinfan]

I agree re. the mapping which is why I'm probably not going to bother. I like the standard PASM setup and I'm surprised you say it's unusable, I'd say it's sublime for a car running 20" wheels

I press PASM frequently when touring twisty bits around Europe, less so in the UK. I find it very good.

PASM is always on. pressing it on the 981 just uses the top range of the shock damping, hence why people say DSC give a nicer ride as it uses 100% of the shock 100% of the time.

I think it's a great system just not quite ready for the mass market imo due to the lack of UK support and maps and software impossible to figure.

I am not sure how a map on a 991 rear engine car is fit for every one.

PASM on atm is nasty if you hit a bump as it cannot go below 60% damping or a figure like that.

which means no UK roads lol as the car tends to bob about a bit imo.

On 19 " wheels sport is perfectly usable most of the time l would only use normal when driving quickly if the road was very bad.

[Twinfan]

Yep, same here. Mine lives in Sport.

Strangely, I use my 981 PASM in Standard all the time, only switching to Sport on the motorway if the surface is bad, and at "higher" speed.
