New to the forums, recently just bought an rc51 and love it. But I was going through the bike and noticed this button. It says led button on the circuit and on the back just numbers. I've tried googling it but I haven't turned up with any luck. I've ran the bike and pressed it, nothing happened. It also has a power Commander and I didn't notice any fuel changes when I pressed it either. Any ideas on what it is? I've traced the wires and it looks like it just plugs into the main board.
