Hi. Is there any chance to get somewhere a proper and valid Siemens 5wp4 ECU XDF (definition) file? We want to fine tune my ABFed MK2, but without that file is just a guessing.
No XDF. It is an old shitter and those who have a defination have done so the hard way via disasemmbly. Done a few haivng made a reasonable defination but with professional tools, for use in Winols.
I have a friend, who has all the tools, but he is into tdi tuning, not really familiar with abf engine. He sad maybe if i get a def file than can make something. What's your advice? I done all the easy mods (tb port, air box, shorter FD)
