that's a very good XDF. i can tell even though you aren't hacking new parameters you spent a lot of time making things right.

i love it when people maintain strong categories so they're easily navigated by people who might not be able to guess at the parameter names. there are so few XDFs that do that, and often when people take a 'clean well organized' xdf and start modifying it the categories go out the window

one thing i wish is the 'level' system in tunerpro was a bit better. this is one of the xdfs that has become so large that no matter how well labelled or organized it is, it can be intimidating to read and find things. i've often thought using an 'advanced' sub category under each heading could be helpful.
