Evo8 rom without rear o2 sensor

[BarryC.]

here is a copy of the rom from my old JDM evo 8 this model did not have a rear o2 sensor as standard,
have noticed that a lot of people are looking for the rear o2 sensor to be removed and not throw up fault codes,
so maybe someone can disassemble this rom and see where the rear o2 sensor is controled from,
