BMS don't do backend flash for S63. Other platforms (eg N54/55) yes.

Halim seems to have the best results with other builds, but I would suggest getting the JB4 installed and tweaked before trying to stack a S63 backend on it. S63 JB4 is less than a year old, so there's not much testing done with flash integration.

What happened to your VELOS tune?

PS - I like your 300-style 22's! Wish BMW had sold the E70 with 22" wheels...
