The benefit of owning the cable is that you can revert to stock or reflash your map again, whenever needed. Like if the dealer does an update and wipes out your tune. That might not be very common, but I want to be able to reflash if needed. Plus, it sounds like if BMW releases a software version greater than 240E, we'll get the update for free.
