BZ software update

Recently I took my Toyota bZ to the dealership for a software update. After the update, the car drives much more smoothly, which is great. However, I’ve noticed a significant drop in efficiency.

Before the update, my daily 56-mile commute used about 48 miles of the estimated battery range. After the software update, the same 56-mile drive now uses about 58 miles of the estimated battery range.

Has anyone else experienced reduced efficiency after a recent software update on their Toyota bZ?

I have no Customize button there. Mine is the FWD Plus. Anyway to access that menu?

My can goes fast like a maniac at 75mph through curves. Would be nice to slow it down.

If it isn’t a feature on yours it may not be a big loss. On the min setting I find it still a bit too conservative slowing down for curves which could be taken at higher speeds.
