Hi all, i am a newbie both to this forum and to the VTX after about 30 years from my last cycle experience. I have been lurking awhile and boning up on all the good info here. I have a new '03 C i just got last month and am having a blast. Just picked up a PCIII USB on ebay but have yet to alter anything although i plan to. My question is: A. The zero map would have absolutely no effect on the engine FI would it? ( why do they even have one? ) B. I haven't found a map for a stock C that would perhaps optimize the engine using the pwrcommander. I would like to try it out before adding anything else. Even better would be a stock map with the desmog done as i plan on doing that. Thanks and look forward to all the good info..
