However, what if you are still in the comfort G box and not necessarily the gforce table - is that what you mean? If so is the speed table not applied to the comfort G box/window but only when you get into the main G-force table? Is the help text not necessarily giving the complete picture here?
Okay... I am going to tell you how this works(despite of how the help text reads). In the Speed table, when the actual g-force exceeds the value entered in "Speed G-Limit Threshold" it will trigger out of the Speed table and refer to the Main GForce Table. So if your lower hanging brake ducts are touching a bump at 60mph, you could decrease the Speed G-Limit Threshold values to help to reduce the compression movement, that is if the OEM dampers react fast enough to these high-velocity bumps.

The G Comfort Parameter is basically another Speed table that operated under 60mph.

I know this may not seem all logical...I did not write this program nor the help text. I'm just trying to help. Don't shoot the messenger.

Then adding the DSC box to that setup and fine tuning it to "tone down" the normal street profile of the rest of the suspension mods, but still be able to have a fully active sport mode was just outstanding. It's why I recommend the DSC as the best bang for the buck mod on the 997 chassis. It's significant enough where prospective car buyers should be looking at S cars just to get the PASM building block in order to utilize your DSC box.

Thanks for developing and continuing to support such a game-changing product.
Very glad to hear you are still enjoying your DSC coming to 5 years!
The DSC does a brilliant job softening the damping force to the nose of a bump and then adds rebound to smooth out the oscillation on the back end of a bump. Really takes that hard edge out of coilovers with racing springs.
THANK YOU for your kind words and support!!

No it's fine, I'm just trying to understand what's going on. I get asked to rejig a few of the guys boxes here in NZ so I need to understand it fully.

Hi. I have a question regarding the standard 9x7.2 calibration file (normal setting). Looking at the GForce tab there is a "dip" in the values for the front dampers from .0g to .6g. Let me list out the front left damper setting at 0.0g front to rear from left to right:

80.0 70.0 60.0 50.0 50.0 50.0 30.0 30.0 40.0 30.0 20.0

So from the central 50.0% it dips to 30.0% for .2g and .4g before rising to 40.0% and then trailing down to 30.0% and 20.0%

My question is why?

Many thanks

Matt

In our development we found that during a constant mid-load range(at around 0.6g) the car is more stable with a little bit more rebound added to inside front damper. This reduces body roll in that load range. Above this load range we softened the inside front damper to be a lot more compliant driving over track curbing. Here's an example image.



If a user doesn't like this feature the user can change these values to whatever the user prefers.

Thanks for the explanation Tom, much appreciated. I may try upping the .2g and .4g values to smooth out the dip...

Cheers

Anyone know where I can download the latest Tuning software? I registered, but perhaps I will just have to wait until they are back in the office on monday?

If anyone has it would love to get it for the weekend.

Thanks

Hi, I have a question re the shock calibration table. I understand that for standard OE dampers 1500mA is full soft and 500mA is full stiff. But if I load up the standard map in the software and switch to Sport I can see that the range is from 1200mA 0% to 200mA 100%. And 200mA is less than 500mA?

Confused

Trying to make the shock go beyond full soft (a value greater than 1500ma can overheat and damage it) but there isn't that risk by using too low a value for full stiff.

DSC does this in some of their maps if you're running the stock dampers. By setting a lower final value and then having the table fully populate with even increments it effectively makes each incremental jump larger, and consequently, stiffer. The OEM PASM dampers don't react as quickly as their Tractive ones, but by increasing the jump increment they can achieve a better overall tuning result.

That is probably why you're seeing that in the table.

^ Spot on Sir!
Don't run higher than 1500mA on OEM PASM dampers.
Lower than 500mA won't hurt the damper, it also won't change the peak stiffness, it do in some of our files to change the shape of the curve in Shock Calibration table.

Thanks Petza and Tom, I understand, it's just to change the shape of the "curve" and you'd get the same results if all the values less than 500 were set to 500?

Checkout our newest video on DSC Sport Active Suspension featuring Tractive coilovers. Going from running 997 Cup car lap times on track to daily street commute in the same car, same suspension setting- No problem!

HELP! I think something's wrong. I just had some suspension work done (replaced camber plate monoball and height adjustment), and now my DSC is running at full stiffness (100%) all the time! The shock percent is running at "500%" and the current is "10mA." I think this is the DSC's emergency mode. What should I do?

Not an expert but sounds like one of the PASM shock connectors wasn't plugged back in after the work was done. The system then detects a fault and switches to full stiffness (fault) mode. I've also read on the boards that the plug can be reversed (turned 180 deg) and it still plugs in though it doesn't work right. Others have said the plug works either way so I'm not sure. I'd inspect the connectors and make sure the plug is fully mated.
