PSM Disconnect Instructions
*Patent Pending
Leaving PSM on at the track could affect high speed handling, lead to engine cut out after long
sweeping high speed turns, and might cook the back brakes. However, this procedure is only
recommended for experienced track drivers. As someone else put it on one of the forums:
This is not something a new owner or first time Porsche owner should attempt. This is not something that should
be disabled for street use. This should only be done for track events and for drivers with many years of track
driving experience. NOT FOR A NOVICE. Porsche put these abilities into the car for safety and protection of the
driver. They should not be changed or tampered with for any car used on the street or any inexperienced driver.

Disconnect instructions (for high speed track driving only):
1. Remove the plastic cover in the trunk, look for the PSM pump under the brake master cylinder.
2. The PSM pump has a wiring harness, about 10 inches long which exits the back of the pump
leading to a connector.
3. Disconnect the plug. (When you plug it back in everything goes back to normal).
