Okay, im new to forums, or threads, however you call it. So bear with me, but i want to learn. Anyway, im also new to bikes. I know how to do mechanical work, so knowing how things work isnt a problem. I heard of something called a Juice Box Pro. I know sorta what it does. But what are maps? Can i "make" them, if im saying that right. If any one could give me an all around about the Juice Box Pro it would be great.
