You can switch maps, log, adjust traction control and adjust throttle sensitivity with it, all (obviously) from your phone. No cord or laptop needed. IMO, it's overpriced by about $200.
The GT-R version has far more features and it's probably worth it on that platform. But if you like to tinker, it may be a must-have.
