I'm trying to build a fully populated XDF for $6E. I'm using an existing file and filling in the missing blanks. I've copied / pasted then modified some table definitions from the awesome $0D definition, but I'm not learning anything by doing that. So I have a few questions.

When defining constants,

For a particular coolant temp variable, I've selected coolant temp as the data type. Do I have to enter the conversion math manually, or is there a way to "tell" tunerpro to enter it?

What should I know about "Stock Units" and "Units Override?" I've seen units typed into the "Units Override" space when the same unit was available in the "Stock Units" menu. Is there a practical reason to do this?

What are the three category entries for? What are the categories that are listed by number?

Should I just RTFM instead of trying to get this done?

Other than copy item, past item, delete item, is there a way to change the order of XDF items in parameter tree?

Thanks.
