recalling my experience with .1 PASM ... DSC will make a noticeable difference.

Is it safe to unplug the factory PASM in a 997.1 to see what the difference is with the factory PSAM off and on? Will it light up the dash or log error codes?

I think it would be fun to experience what the car is like without PASM... and then with DSC...
Winter is about to hit so ill wait till the spring...

It will do both; my understanding is that you can drive the car with PASM disconnected, it will throw a fault code and light the "!", I *suspect* that code may not be transient, i.e next time
the dealer plugs in PIWIS the codes will appear on their logs...

I'm just there to have fun. I have an itch for a track day. I haven't passed 6.5k rpm on the car in months.

Also, I am running stock suspension on my 2008 .1 and the DSC is awesome. Street/freeway tests only to date.

Yes it does! Makes it wife approve ride! After this mod, she might want a GT3 as a DD For herself.

I have not driven a car with accelerometer upside down so thank you F1CrazyDriver for being the first and for your feedback.

I had it upside down & with wires facing back, not forward per instructions(as you can tell I was very excited to put it on the car I forgot to read instructions!), it felt good for thinking the car was upside down. Felt like a M3/ Turbo ride quality, to me.

Basically the front doesn't get as much stiffness as intended during heaving braking and the rear gets more stiffness than intended during heavy acceleration. It might still be better than stock. Thanks for finding this out for us!

Ah! That's great. Thanks, Larry!

For the .1, sounds like it's more elaborate. @Tom, is there a PDF up with instructions? I'm considering grabbing a few for some .1's and .2's.

DSC and accelerometer installation on a .1 car takes me less than one hour. More time required when there's a roll bar. The accelerometer wiring involves tying in 3 wires and a ground. I haven't made a PDF but I have illustrated the installation on two cars in this thread-

We're down to 5 units in this run. Next run will be at least 6 weeks away.
