Just heard back from one of the vendors, and they say an FSC code is not needed for ACC. They did confirm that ECU reprogramming needs to happen if a software update occurs. FWIW, they say the retrofit is easy.
Well, at this point I'm not finding any other M550s with the other packages I have within 500 miles, let alone color/mileage.

What packages did your G30 come with? So the kit price they're quoting of $1.8K seems reasonable (if harness if plug and play, as they claim).
