Most people use tunerpro. To do so you need to know the operating system id of your computer (OSID) and use that to find a matching XDF file which tells tunerpro what is in the XDF and how to edit it. XDFs can be found on pcmhacking.net and other places. Also check out Universal Patcher which does a lot more than just patching!
