Not sure what the deal is with Bluefin as regards Mini's...................... BUT ..........................
For Audi's you get a Bluefin handset that you connect to you Pc and upload your standard map to Bluefin and they send a suitable remap via your Pc to the handset. If their are any problems with the remap you can upload/download several times to get it sorted. Its a very handy facility and well thought in the Audi world.
seems it can be, i just bought one from the guy in question, he had it on his mini and sold the car WITTHOUT sending the map back to the car first and he rung them and they told him to hook it up online, he did they reset it and i bagged it from him for 130 quid. bargain.
you can plug your bluefin in to your computer and send superchips the contents of the bluefin and they can adjust your map to suit your problem, like with mine why uploaded the settings and told me that there was an error with my ECU
