Just curious. Since my 40/60 only gets 128 miles when fully charging with 5.8 firmware, it makes me to consider upgrading to 60.
198 with 13000 miles on the car at full range charge.
205 with 5,500 miles on full range charge.
201 w/ close to 10K miles.
202 w/ more than 9K miles.
You get the same range you always did, now it just estimates it differently.
My 40/60 now reports 135, previously 141.
More important Vincent is has your average watt/mile gone up?
If not then it's all just software updates not really your range. I finally just set my car to Ideal. I've been driving long enough that I just know what range I will make looking at the average watt/mile based on how much charge I have.
Mine actually increased slightly to 208 with the latest update and I am at about 8k miles...
208 at 10k. Range charged first time last sat.
200 with 22k miles.
185 with 23k Miles
200 with 31K miles. Likely higher as I didn't check it until about 5 hours after it reached 100%. Tesla does not trickle charge, so the range/SOC will drop up to 2-4% over time after reaching the set SOC before starting the charge up again. This means it could be as much as 8 miles of range higher for me.
Best is to measure the range about 1 hour after it reaches 100% SOC for the most accurate reading . It may do some cell balancing during this extra hour, so slight charging may still be going on after reaching 100%.
