2022 Lightning Lariat Range Boost with February 2023 software update

Folks, when i took delivery in September 2022, this truck which was supposed to have a 320 mile range, would never show a range greater than 240/250 miles even when 100% charged.

The software update came through and i installed it a week or so ago and now at 100% charge it shows a range of 340 miles?

Has anyone had a similar experience? Any experience to see if this new much higher number actually is accurate in real life?

Yes, this was posted a couple of months ago and there are threads about it here. It was part of the enhancement to the Guess-O-Meter, officially called the DTE (Distance to Empty) indicator. This is not the way to test your actual range as it is a black-box calculation that doesn't know where you are going or how fast.

You might want to start here:

then read up on PowerUp 22-PU1009-MIL-DTE
I frequently drive from Vancouver BC to Whistler BC, usually once/week. Total distance is approx 250km (we are Canadian after all!). The drive is always in the winter, average outdoor temps are -5C to 0C. Since the update (about 2 weeks ago as it would not properly update the last time I tried about 2 months ago) I am seeing way more distance to empty than before the update. About 20% more.
I was suspicious when I noticed the DTE figure at 100% charge increase from approx 350km to 450km since the update. I suspected that DTE figure would go down quicker than before but that has not been the case.
Not scientific by any means but a noticeable difference. I think that Ford has allowed more access to the battery. They were uber conservative when they produced the truck (after all they have to guarantee the battery for 8 years) and they have realized that they can allow a more aggressive strategy.
Just my 2 bits!
There is no indication from sources inside Ford that the amount of battery accessible has changed. It is only the DTE calculation. If you really want to test the amount of battery accessed you need to do full range tests.

Wouldn't the 2 go hand in hand?
