I love this too much. my scooter is a mess, I got it a new controller that is tunable, but there is a difficulty in determining what wires do what, and the new tunable controller is scary and is asking for a lot of things that is difficult to answer without a complete tear down. The amount of work and frustration is something I actually look forward to, because it ends in a way I can handle, and probably might have to do a buttload more work do get working, but that end light never dims :)
