I think a few people have been using the 551 files on here (sometimes touted as being R32 files) to build turbo R32's and the like and tune their 7.1.1.'s.
Here's a couple of screen shots of the bits missing from those files;
NWA - Nokenwellen abgas (or however it is spelt) - i.e. exhaust cam - inlet only VVT on the 551's
SU - Saughor - Inlet/Intake manifold - you can see the change over barrel functions of the R32 and 24v VR6's here
So bit of info and some addresses to hunt down some potential map areas for the VR/R32 owners
