Opensource systems like oft and tactrix only modify the code area between 8000 and 13fff hex. The section between 0000-7fff is just padding and not written. Some systems pad this differently eith ff or 00 characters.
Their is no vin or other unique info in the section written so an A01G rom is same whether it came off a subaru or toyota, so no real reason to never edit your stock rom as long as you have an original somewhere. Or someone elses original.
Ecuflash srf format stores some vin and other data but this isnt written durjng flash, its just for the tactric guys to aid rom identification and dissassembly.
