As I've been working with Tesla to determine my reduced max range and the suspicion was imbalance I did a couple of range charges just before getting .106 (was on .94 I think). The last few range charges came to 505km of rated range (before it had dropped to 496km even with the new 5.9 where I gained from 486km so it had some imbalance). Then I got .106 and did immediately again a range charge to continue the balancing effort and voila the max range had dropped to 498km and seems to be stuck there (I've done a couple more range charges and kept the car balancing). So I lost 7km overnight with the new firmware and hence am putting it to the firmware release. Anyone else done a max range comparison of .94 and .106? Not sure if the estimate got more accurate or the range was moved below 0 again.
Are you sure you don't mean 396 and 405km, respectively? 505km is a ton! You must have a super battery.
