Im ready to do my ROM flash with ecuflash nut i have one question.
Basically I got to different ROMS one for 93 and on for 91octane. Both for a 2002 wrx
the porblem is they both got different internal id numbers.Do I need t oworry about that or Do both of them work for my car?
Internal id: A4SGE01C (91 OCT)
Internal id: A4SGE00C (93 OCT)
