The defs are there, however the admins may restrict new users from downloads/uploads for a number of posts and/or days. I'm not sure. There used to be a lot of spam, so I'm sure some steps were necessary.
only the metric definitions are applied. if you want to tune/log in standard units (psi instead of bar, for instance) then you still need to download the definition.
got this info from the sticky thread for romraider/ecuflash on nasioc.
