I've been using mine for about a month in the car now and it's a definite improvement, even driving normally if feels like there's more rebound and the car has lost that "floaty" feeling it has when previously driven in PASM normal.
I wouldn't say, for me, that squat & dive has been eliminated, it's been significantly reduced as has body roll on the street at least.
I took the car to our fastest local track last weekend, Phillip Island, and was able to take 1.5 seconds off my previous best lap time there. I also changed from Cup 2 to Dunlop Sport Maxx Race tyres - which should have had some benefits. The weather was also good in the first session when I set my best time, couldn't manage to go any faster throughout the rest of the day but was consistently within 0.7 seconds of my best time the whole day. I've also only been to this track twice before - so there would be time in that as well.
The car definitely felt better than it had done the previous time there in December. I probably had my tyre pressures too low as well, giving the car a softer feel, anyway - there's a lot of variables so read into it what you will. As has been previously stated by the DSC guys, it's just one part of the handling setup, it's a definite improvement without any trade-offs for me. I should probably get a second set of wheels and better tyres to get more out of the car anyway.
My best lap for reference, the camera was a bit loose unfortunately, but you get the idea. Much improved stability at speed.

The values should be different in the Shock Calibration table between the two modes. If you wish to make feel more distinguishable between the two modes for lighter load driving conditions then the easiest thing to do is reduce the numeric values from 0-20% in Shock Calibration in Sport mode.

Tom (or anyone), could you explain what the following settings do (on the new 2-mode unit) and how best to make adjustments?
Default rate (Lng Rate)
Lat Rate
Sensitivity (rate trigger)

I am an avid fan of the PASM replacement unit!This unit has transformed my GT2.A shear pleasure and absolute joy to now drive as a street car!But still an animal at the track or for some spirited driving! Michael you are a god to me!Tom thanks for all your help!

As for how best to make adjustments, it depends on what you want to achieve. There isn't a right or wrong way. The software offers a number of ways to change damping characteristics. The most popular way is using Shock Calibration table.

The current DSC software that we are all using is actually the raw engineering version. I was told by the engineers that these three functions are there for them to calibrate the g-table and g-table patches. For now the engineers prefer us not to use these three functions. But in the future we will make videos to describe their functions.

Silly question, but how does changing the damping stiffness affect understeer/oversteer? For some reason, when I run stiffer shock calibrations in the front (relative to the rear), I get MORE front grip (I thought it would be the opposite, like stiffening the front swaybar).

Any chassis tuning method can be situational. If the situation is such that the front is under damped, then by increasing damping force the front will have better grip. Another example is some tires grip better with higher pressure than others. Even with the driver taking a different line, delaying or advancing brake/throttle can triggering a different results or just back to the example of the particular tire with X amount of tire pressure happens to works better with more damping force. There are many variables. That's why race engineers get paid the big bucks during race events to determine best course of action for the given situation with all variables in consideration(driver included).

DSC causing Durametric error?
I did a routine scan with the Durametric Pro earlier today and am getting the following error that is persistent (cannot be cleared).
8007 Gateway incorrect coding
I have had the DSC unit installed for over a year and vaguely recall a potential issue here, but have not scanned car's fault memory for a while. Did not find any references to this error on the forums either, so thought I'd ask the question; could this be caused by the accelerometer installed as part of the DSC solution for a 997.1 GT3?
Any insight is appreciated.

Do you have a Dension or Mobridge type device for Bluetooth installed? This error generally relates to that and can be ignored.

^ I agree with nzskater. I see coding error of this sort with non-factory radio and nav system. Unrelated to DSC module and DSC accelerometer from what I have seen. The vehicle performance is not effected by these coding errors. My car did not have coding error with DSC and accelerometer. But it does now as a result of installing racing seats without airbags.

997 GT2 with Cup 2s, solid links everywhere, stock suspension settings, full DSC Tractive package with Swift 616lb rear 336lb springs.
This car is ultimate 800hp daily driver, set up for response with 1.4 bar by 3200rpm.
Just picked it up after having some service work done and I took a passenger seat test drive with shop owner Phil Hindley who is an accomplished and experienced 911 racer.
From the passenger seat the incredible suppleness of the ride is even more apparent it really soaks up the ruts and bumps yet when some G is loaded in it firms up instantly. Phil was very impressed with it and was commenting on how it felt like it was making a lot more grip with this set up and is a real improvement in putting the power down, I’ve no doubt he will be recommending it to other clients – well done TPC
