i was cleaning bike and puttin me a charger pig tail on when i removed the side cover on my 2005 roadking, i found a clear box mounted to the frame and it said Vance& hines fuel pac etc. the red glowing letters were lit when i cranked it to 0100, what does it mean, and how do you adjust it? i see little black push buttons, but what all can it do?? p.s. the bike will fly just like it is, but what can you guys tell me about the thing?
