U-Scan http://www.actron.com

Now this tool is very cool. It works off or your Iphone or android. No wires just a little plug that stays plugged in if you want. I tried it and not only does it delete codes it shows you where they could be found and does the complete data logger with freeze frames.

 

This just looks like a universal OBD2 scanner with PC logging abilities. I don't see the Porsche specific parameters like variocam timing, etc.

 

Try it you will like it.
