You cannot have PSE on without Sport on. No way that you can do it. You can select normal for PASM afterwards and you could turn PSM off, if you like, but you cannot have PSE without Sport turned on, period. The only way to do it would be by unplugging the harness at the engine bay or disconnecting the vacuum hose in the engine bay also. But then, you will have PSE on all the time without being able to disable it! What was Porsche thinking is unfathomable.
I believe there is a way to engage the PSE w/o activating Sport Mode. If I recall it requires adding a switch & wiring to remove the +12V from the vacuum solenoid. Do a search on 'PSE' to find more details.
Here's the 'MOD' I was referring to:
PSE Modification from RennTeam Forum
The purpose of the factory cut-off is to comply with residential area noise regulations in some countries (Switzerland for one )
At speeds up to ~ 50 mph the PSE will cut off whenever the throttle is used agressively .Above 50 , it stays on loud.
Here is how the PSE works:
The PSE mufflers have two pipes coming out of each muffler.
Each muffler has three chambers in it.
The bypass pipes have a damper inside, which when closed , makes the exhaust go thru the entire muffler. When open, the exhaust exits already from the first muffler chamber (loud).
The dampers are vacuum activated and are normally OPEN (loud position )
The vacuum hose has an electric solenoid valve (12 v)in it, which is activated by the cars computer and controls the vacuum to the dampers .
The solenoid valve is normally CLOSED .
You can install an on-off switch in the solenoid valve electrical wire. If no voltage goes to the solenoid ,it closes and does not allow the vac. to close the bypass pipe dampers and the PSE will stay loud, irrespective of what the computer does.
You can find the electrical wires going to the solenoid if you remove the carpet behind the rear seats ( pull up in the center of the car and just remove it )
then unbolt the metal plate above the electronics ( passenger side) and look for the two wires exiting into the engine compartment(far left corner , looking to the rear )
Cut the red/purple wire ( +12v ) and splice an on/off switch into it.I installed my switch in the console ashtray.
You can run the wires to the front of the car by tucking them under the plastic trim along the passenger side.
All you need to remove is the storage tray under the passenger side door.Pull out the rubber cover , remove one crew and pull it out. Run the wire thru and replace. After that, again, tuck the wire behind the passenger footwell covers and around to the center console .
The easiest way to have the PSE on loud all the time is just to disconnect the orange plug to the solenoid( located in the engine compartment)
Another way is to disconnect the vacuum hose to the PSE dampers. But then you have to make sure that the hose is properly plugged, since the cars vacuum system is used for other things as well and you may get an error message .
