Plus what other modifications do you need to do to the e90 e92 platform before besides the ebrake shoe for the bigger brakes to fit?

BPC provided a USB flash cable and I was able to email them my ECU information. It took about a week for them to get back to me with the tune, and it was as simple as plugging back up to the computer and reflashing with the new tune, which took about 45 minutes if I remember correctly.
