Based on what I saw from Suuto's DM, and how it appears to be stored in the DC menus, I suspect the pressure start/end are stored in some sort of header.  I don't see profile based pressure points (may be there but not that I can detect).

my Suunto Vyper air works properly with the pressures. Have you updated to newer daily build IIRC your version was quite old. Or tried with the latest release?

The dump file can be fed to Subsurface with simulator. It is the pure memory the DC has... We should have instructions on our webpage, but with phone, won't try to find the link for you...
