There must be a better way to get an XDF?

they're made either by data sheets from programmers (which are rare and usually have to be acquired by back door means), or by painstaking disassembly of the ecm program. seeking out tables in raw form is a good starting point, but doesn't get you far.

there is no 'easier' way, you are doing the easy way (which also yields the least amount of useful tables)

Thanks for the response, I realize this will give me just the basic most surface level maps to work with. I just don't know of any other way.
