I'm not sure that messing with the eprom will help much. As far as I know the main thiing Dr Rossi does is advance the timing. As far as I can understand this makes it easier to tune the bike for some reason. You really need a pc3 for what you're talking about. I don't really know much about it, but this is what I've gleaned from Dr Rossi's posts and what griff has said in the past. ching either one or both of them an email and I'm sure they will explain in actual facts, rather than just vague ramblings!!
