997 sport exhaust, bad news.
There are some bad news regarding PSE for the cut out between 50 and 80 kmh.
In the 996 Gen, it was easy, it was a flapper valve directly related to the tachyometer, so that the exhaust goes back to normal position between 50 and 80 kmh. All that has to be done was to disonnect that info from the Sport exhaust and let the switch on the dashboard take care of it, so that only the driver decides, now I (and other clients) had to sign a responsaibitly discharge stating I was responsible for driving between 50 and 80 kmh with PSE on, fair enough.
Now on the 997 gen, it not only depends on the speed but directly on the DME!
It now regulates itself on variables such as speed, revs, and even temperature!
It is much more complex, infos are taken from the ABS sensors and directly sent to the DME via the new generation Bus Can system.
Basically, even the top technicians in Paris are desperate (they've has two cars with PSE so far), I quote:
"With the 996, it was ver easy, now, it's a nightmare! And for the S version, it is the same switch as the chrono sports, so there is no way I'm gonna start playing around with the car! I'm a good mechanic, I am not a software engineer! "
As RC said, maybe one day, there will be a solution, but definitely not for now!
I am puzzled, when sport exhaust was mounted on my 996 car, it did have the flapper valves automatically actuated between 50 and 80 kmh (Which is BTW due to legislation, noise legislation are measured at those speeds)
I guess I could live with it, but I admit too that it is a royal pain in the arse!
Plus on the 997S it comes standard with the powerkit, I'm just hopeful that a solution can be found, but it won't come from the factory.
