Just came across this thread.
Your parts will be in on Wednesday
If you don't have combox now but want to get it, we can always retrofit this in the future.
Not sure if you have a 6MT or DCT, but if 6MT you might also want the 6MT launch control feature:

Other tuning features you might want are the cold start rev limit reduction, and maybe the cold start cam phasing shut off.
BMW Live is available only if you have the Combox.
Safe travels and we'll take good care of your baby when it comes in.
