Warren,
I can't help you with the traction control, but the cold start issues on the V7 are well discussed. On my bike (a '09) I first used a modifier for the oxygen sensor, and then moved to a programable ECU; MyECU from Australia. It's great, but it's only for the "old" pre-2013 engines.
I believe for newer bikes the Guzzidiag ECU management system is the way to go. But it's for people that like to get "hands on" with their bikes.
