however, I'm starting for passion.. for the pure case on the forum of my "astrina" one guy made a guide on how to exclude the egr from the map... and l? I discovered this world. I thought that in order to do the mappings, etc, etc, we wanted equipment that cost a lot, then I saw that there are equipment of a few hundreds of euros that allow you to dabble in this hobby and see if maybe ? only a euphoria to the news? or for pure passion. And then, perhaps, one decides what one wants to do..! a course I think that the far?.. if you are not extortionate prices even why? ? only for cuoriosit? and 'play' with their own means, not for profit as many do!!
