Hello . I'm planning to buy the Delphi DS150E interface. A friend connected to my old 1.8 TDDI MK1 focus from 99 without any problems. I'm also going to connect with Peugeot 307. I would like to buy such an interface for myself, I am wondering how the 2014 R2 software differs from 2014 R3? And how do you generally recommend the interface, is there something better at this price? Regards
