Well this is my first post on this board.  I have been lurking here for a while because  I am considering buying a Boxster in the near future.  OK now to add to this thread.

I found this the other day while browsing other websites and forums.
This is a detailed, with pictures, install of the PCM in a non factory PCM car.
Doesn't look like its that hard.  
 
Peter Joyce, if you decide to do this, let us know if the website I posted helps.
 
ckreling, one of the things that  I will be looking for, is a car with the PCM in it.
I hear its pretty rare, but my current car doesn't have it.  Most of the guys I know
with the same car, 01 Acura 3.2 CL Type S, have it.  I dont know what I was 
thinking when I DIDN'T get it.  My next car will have it. 
 :dance: my first post!!!
