I recently completed installation on my 2011 Spyder of the PSE retrofit sold by Suncoast. I used the Porsche Installation and Conversion Instructions for the install and everything went smoothly. I had planned on taking the car to my dealer for coding, but, to my surpirse, I was able to code installation of the sport exhaust option in Gateway using my Foxwell NT520 scanner. After coding, per the Installation and Conversion Instructions, I started the car to confirm that PSE was operational. It was. When pressed, the button opened the exhaust valves and the light illuminated on the PSE botton. Fast forward a few days. I again started the car and now the botton does not activate PSE and no light on the PSE button. The exaust valves close moments after startup, which tells me the vacuum/electric change over valve and other components are working correctly. The PSM botton works, so I don't think it's the switch panel. I have tried uncoding and recoding the sport exhaust option in Gateway, and no change. Any thoughts? There does not seem to be a fuse for PSE in the 987.2.

 

By way of update, I rechecked all of the wiring yesterday, and everything is correct. While I had to combo switch (containing the PSE botton) out, I started the car and PSE was on. I plugged in the combo switch, and PSE stayed on with the light on the PSE button illuminated (but it would not turn off). This has me focued on the PSE switch. To test further, with the car running, I jumped the A3 wire (12v) with the A10 wire (PSE control) and was able to activate and deactivate the PSE, so it may, in fact, be a bad switch. I called Suncoast to seek a replacement and, while willing to replace, they are of the strong view that programming by the dealer is necessary. I explained that I was able to successfuly code using the Foxwell and that the wire jumping test seems to suggest that the PSE is functional in the DME. They were not convinced. So my revised question for this group is can anyone confirm that dealer coding is necessary?

 

Can't confirm is dealer coding is necessary, but I can say the exhaust valve closing after start-up is purely a mechanical function of the vacuum line being connected. The exhaust valve is naturally open when no vacuum is applied from the engine. If the electronic PSE system were not functioning, the valve would still close like that immediately after start-up.

 

Zach, thanks, and agree. I am able to turn on and off the PSE system by jumping the wires noted above (A3 and A10), which is what lead me to suspect the switch. The DME and electric change over valve are working as they should to control the flaps. Today, I was able to set up a test bench for the switch, and it is, in fact, bad. The buttons are designed to provide a 12v pulse upon pushing the button. The button that I have has a fault in the circuit so that 12v is constant whether the button is pushed or not (it acts as if the button were pressed and held down). Sucoast is sending me a new switch, which should solve my issue. While the dealer is needed to code the Sport button, I do not believe it is needed for the PSE button. I will report back after I get the replacement button (which is weeks out) just to confirm and close the loop.

 

I have a similar problem but it never worked and my car is 911.1. Dealer is in day 2 trying to figure out why the Sports exhaust button will light up but not actually do anything. At the same time the Sports plus button doesn't light up or do anything. How did you get Suncoast to send you a replacement button? I purchased the PSE kit from them.

 

I called Suncoast and told them that I had a defective switch. They pushed me on it (indicating that they have never had a defective switch returned), so I undertook additional testing to confirm that the switch was in fact bad. They then agreed to replace. I have since installed the replacement switch and PSE operates as it should. No issues. I can also now confirm that you do not need a dealer to code-in PSE on the 987.2 (I was able to do it with my Foxwell). Hope this helps.

 

Did you send back the switch? I wonder if i ended up with the bad switch. Mine was shipped from them on 11/23.

Super helpful follow-up post right here. Glad you got it sorted.

 

I sent it back on 12/2, so different switch, but maybe a bad batch?

I ended up with a spare switch from another vendor (which I ordered when I wasn’t sure if Suncoast would exchange). Happy to send it to you to help troubleshoot yours. Alternatively, I can tell you how to test the switch circuit with an ohmmeter. Send me a PM if interested.

 

My issue was resolved yesterday by replacing my rear end control unit. Closing the loop for anyone who has a similar issue in the future.
