Flashing doesn't matter, you can use the same 8858 rom, its the same file just interpreted by ECUFLASH with different as in updated XMLs. Make sure you reread the first post as to what its intended for. These tables are meant for at minimum V7 of the 8858 rom.


is 8858 your native rom or is 8884 your native rom?

 

My native rom is 8884001X
so should I open my recent Tephra-v7 xml file (as notepad) , then copy what is in the (new improved xml) as select all , and paste it in the old 8858 xml file ?
or
delete my whole old 8858 xml file and replace it with the new improved 8858 xml file ?
and how to rewrite to my ecu ?
Thanks again bros
