I will be fitting a unit to my 997.1 GT3 and possibly remapping it to my own preferences. There seems to be a lot of scope for tuning during different the phases of the corner.
on a car like the 997 a set of Road and track Ohlins are only double the price of a DSC unit, it's a tough call to go DSC on the older cars imo.on cars like the GT4 where the Ohlins set up is £5k trying DSC to stop dive and roll seems worth a punt.
997 GT3 I would change the shocks every day of the week myself.
I do follow your logic. I'd fit JRZ which are £4-5K so the saving on a DSC unit is more substantial. My reasoning is actually based on following a friend's modded GT4 at Silverstone that also has the DSC unit fitted. I was very impressed how well planted the car was. I like the concept of allowing more transfer in certain phases and less in other phases. Sounds fun

Tims car ?I think the GT4 is a bit under Sprung at the front, so the DSC really helps the drive and roll.
GT4 is planted anyway esp if it's Tims car , he has CUP monoball arms all round and track geo on it.
If it was Tims how did you find it for performance, as he is running the 420BHp ? I have not seem him since the BHP upgrades.

I quite like the idea, and it seems it's better on the gt4 and 991 platform than the older cars.
Disagree, the electronically variable damper is still much the same Bilstein one afaik but the software control has got better in the 9X1 gen cars which is part of the reason why they generally run better on the road. The older unit imo would therefore benefit more from the software change.Yep. Tim's car. It would have been around September last year, cant tell you too much about the power. He'd told me about the upgrade earlier in the day, I was bedding in some pads in the 997 Cup and followed him for a lap. The ride/damping control was extremely good. I share a simialr view to you Re; PASM but this was in a diffrerent league to a stock GT4. The car was not unsettled anywhere. Just smooth and flat. For the money, a very worthwhile upgrade. The map would be quite different for a GT3 but the concept and control will be the same. I think that Damping maps will be the next big area for performance gains. I'd like to try a few ideas that I have about pitch and roll in different phases of the corner. like I said, could be fun!

Yep, the older cars will benefit most, but you will need to fit an accellerometer when you fit the unit. They are not expensive, basically both the accelerometer and the control units are plug and play. Steve Rance said:

Some differing experiences on the 997 cars then...can only assume this might be down to different maps being used??
Does anyone have any idea how many 'official' maps TPC have created for the v1 module (preferably for 997 application)? If not I might pick the TPC rep's brains over on rennlist and report back.

For me it made the car too soft unless really on it, I am trying to fine tune it but it's a bit of an ordeal sending to the US all the time. Will let you know if I find someone in UK.

Hm...your experience sounds much like another PHer who i know put one on his car at around the same time I did and also thought it was much better on the road. Am starting to wonder if there's not something wrong with my car now 
or perhaps I'm just not particularly sensitive as I have to admit I always thought the RS was very decent on the road anyway....
I have one from 9e on my 7.2RS or perhaps I'm just not particularly sensitive as I have to admit I always thought the RS was very decent on the road anyway....after SFO's experience on his 7.2 Gt3
my belief was that it makes use of the extra information available on which the older pasm controllers fail to program in thus benefitting older cars more than newer ones. My mate in the U.S who extensively tracks his Gt4 has taken it off his car after upgrading springs and found it no faster on track.
To your point on the RS, I haven't tracked mine for the last 4 years and on the road, it does feel slightly more compliant and less affected by bumps but it isn't massively different. I haven't tried the sport damping mode yet though.

that's interesting. I'd have thought that with a hardware change the dsc unit would be even more useful as it has a greater range of parameters that it is able to work for the damper settings with compared to OEM control unit. Unless the spring change was a very different one that takes it out of the damper range I guess..
