Alright, so just bought a z650 with the power commander v and two brothers exhaust already installed. Having zero understanding of any of this, I’m slowly catching up. My issue is, two maps were previously installed. One runs great, while the other chokes out fuel and studders when accelerating. I plugged in to PC and the numbers jump from +17 to -14 all over the place. Obviously something is wrong. I went to their website, but only two maps are available to download and neither apply. Being extremely new at this, can someone please advise me on where I can find maps for the power commander for my 2017.
