Welcome to the forums! If you just mean that the default has changed you can, of course, change that back. It could have been something unintended during the update. If you're suggesting that your car is still set to charge at 40, but is only actually charging at 30, others have reported similar things, but at least one person noted that eventually the amps ramped all the way up to the full 80 amps they were expecting. Edit: Just go back and read the last couple of pages in this thread, and I think you'll see what I mean.
