Its more to do with the sound profile that gets updated too I believe. However, although I was happy with out it, my wife commented that the sound wasn;t as good on this car as the old
280. Even with sound deadening that the
280 didn't have.
I have cranked it up yet anyway, as we had my daughter with us, and sadly the central screw piece that holds it all in hadn't arrived on time, so awaiting that in the post before I crank it up (along with the Seat Sound
stickers).
As for the flag, I've been looking around to see if this flag can be added, as I have since seen a
Cupra R ST with the flag enabled, and you would think the newer R ST's would have the Rev B units. So the guy that installed it is going to have look into it. From what he's seen he thinks ODIS decides to enable it or not.
