If you dont care about your warranty, then pay for a bench unlock, its about $250 USD + shipping, after that you can load BM3 or whatever tune you like!

Otherwise you will have to wait for someone to figure out a OBD2 way (without physical bench unlock) for the S58 ECU (It should eventually come) as it should be the same way for the locked S55 ECU.
