My 2023 RZ450e will get a software update next month when it goes in for its next service. Has anyone else gotten this update and are there any improvements (or issues) that you are experiencing?

I got the update at the dealer and my initial impression is that it now holds a higher charging speed longer while at a fast charger. Ie, it is no longer as suppressed / throttled while charging above 80 percent state of charge. It was noticeable. Also seems to be an extremely modest improvement in range but nothing that changes by usage of the car ie still not a road trip car. I now have the little percentage number by the meter on the instrument display that shows state of charge of the battery.
Maybe it's just summer and ours had the % before, but it seems the range calculation (GoM) may be more accurate and the efficiency seems improved. We are getting 3.8 miles/kWh so far for June, when 3.2 was more typical. I can't imagine it's improved THAT much, but I will keep tracking it.

3.1 -> 3.8 miles/kWh is inline with my improvement in energy consumption between April -> June.
I have not had the suftware updated yet, since I haven't had the need to go to a dealer, and it's a hassle. Maybe later this summer, or fall...
Confirmed. They definitely updated the GoM. Instead of losing about 40 miles every time you turn on the HVAC, it seems to calculate how much it's using instead; what a concept! Now, I lose 5-7 miles when I activate the HVAC, with my testing over the past few days.
It might be time to do another "Zero Hero" test as well, to see if they adjusted the buffer.
Entering my first NY winter with the new software on my 23 450e, I am finding a big hit still with heater vs no heater (maybe 40 miles ish) but the total range is significantly higher.
I recall for 23-24 and 24-25 winters if it was quite cold the fully charged range could easily go down to 140-150 miles or so.
Recently at 25F I had 191 miles of range at 100 percent battery charge with climate control set to 72F.
