The O2 mod will just plug in, no need to do anything else with that. There are downloadable maps on the power commander website, and on here, but there wasn't one for a 2012 model, so I am having mine dyno'd to get the best fuel map I can with my model and mods (arrow cans, stage 2 DNA filters)
there is a list of dynojet centres on their website, find your nearest one and ask for a price, mine will be roughly �180 for a custom fuel map which is 3hrs dyno time, but hopefully a bit less
I was hoping to stay and watch, but have an appointment elsewhere so have to drop the bike and pick it up when it's done, I will let you know how I get on
