Swithcing off PSE

[Marc-911]

Is there a way to stop switching automatically to "normal sound mode" between 30 and 70km/h?

Thanks in advance!

I suspect you have a factory installed PSE that goes to the 'quiet mode' at low speeds. It must conform to German noise abatement laws.

There are a few things that you can do to work around this 'auto switching' behaviour.

1. You can remove the connector going to the PSE vacuum solenoid to force it to stay 'loud' all the time. No DME control.

or

2. Install a separate switch to the control the PSE vacuum solenoid. This switch would simply open' the wire providing the +12v signal to the solenoid. You would have to splice into the +12v signal from the DME to the PSE solenoid. When the switch interrupts the +12v signal you would be in the 'loud mode' all the time. When the switch doesn't interrupt the +12v signal the DME would have control over the PSE.

No. 2 requires you to install a switch (typically placed in the ash tray compartmart) and perform the required wiring. It's not a big deal but is does requires some mechanical & electrical DIY skills.

FYI: I have a switch controlling my PSE so I can turn it on or off depending on my mood. It's in the loud mode 99% of the time. It's off when the wife is in the car. She doesn't appreciate the sweet exhaust sounds.

I hope my suggestions help.

Good Luck!

Where do I find the "connector going to the PSE vacuum solenoid"?

what do you mean Dme control?

If you have a factory installed PSE w/ Sport Chrono the DME controls the vacuum solenoid when you're in the 'Sport Mode'.

The DME is the generic term for the engine management control unit. This is the control unit that controls the engine and also received inputs from the Sport / PASM/ PSE buttons on the center console. The DME activates the PSE as a result of the PSE or Sport button being pressed if the car is specced with the system.

can you tell me where exactly "something opens" in mufflers ,or in catalysts,or after them?

i am asking that so to know that if i change for example my mufflers i still continue to use this system.

thanks in advance!

PSE flaps are integrated in the mufflers, which are different in construction (especially inside) than the stock ones.

[ILIASGK74]

so if i want to improve my exhaust i should change after mufflers so not to lose my use of sport button?

if yes what are you suggesting me?

There is no solution if you want to upgrade the exhaust and keep the stock PSE usable at the same time, you can go for an aftermarket sport exhaust, which are always loud. The SPORT button keeps preserving the other functions as normal.

[ILIASGK74]

to improve exhaust is only change mufflers?

if i change my catalysts and rear silencers will i see difference?

Getting rid of the Cats is like getting rid of the

kitty Box. I always looked at the cats as exhaust

going thru a filter.

No Cats and Yes you will go faster.

Ther are primary and secondary cats in the exhaust i beleive. I know that strosek offer a performance switchable sports exhaust for the cayman/ boxster , there is probaly one for the 997 too.
