After upgrading the software on Sept 13th, my car is finally showing a full battery charge predictive range above 40 miles as it did the previous 9 months. I'm not sure why it was showing less than, or no more than 40 mile range for two weeks after the upgrade, but it had me concerned I was never going to get the high battery mileage predictions in the mid 40s and I thought the upgrade was to make the car more efficient. This morning it is up to 42 predicted miles. All seems fairly close to normal again with that aspect of the car with the newer software and I hope the predicted miles return to 44-45 as they used to. A sigh of relief....
 
Sounds like the FL temp might have something to do with that. Is it cooling off there?

Mine jumped up without a software upgrade. But it jumped overnight from a real world (not estimated) 31 mile range to a real world 42 mile range. That was wierd.

It's now slowly creaping down to around 36 real world.

Wish I had more of the data of the car to know why the dramatic changes with very little change in outside temp.

I upgraded on September 28, and my estimated range decreased from 44-45 recently to 40 miles the morning after. It's hard to say if it still loves me the morning after or not. ;)
 
There was nothing that was changed in the updates that wuld or could have any affect on range. Are you sure it wasnt TTT?
WOT
WOT, remember, we are not talking range, but estimated range, the number that shows up on the DIC screen and on RemoteLink after a full charge. Many Volt owners noticed a change in the estimate the day after they had the update. Do you think they all changed TTT at that particular time?

I remember mentioning to my wife that the estimate might be lower than before and was just happy that it was 40 and not 38.
 
What, please, is TTT ? It's not in the recent list of acronyms that were posted
It's GM's way of saying YMMV (your mileage may vary) as applied to Volt electric range. Let's see terrain, temperature, and something else I can't remember that means whether you drive like a hypermiler or a speed demon. Oh, yeah, technique.

LOL :D
Would have hoped you were kidding...but I guess not.
 
The update did not affect my range prediction. I still see 40-42 miles every morning.
Got my upgrade yesterday and got the car back without the battery being recharged....(boo!) so this morning was the first real range prediction. I have been getting a prediction in the mid 40's - - sometimes as high as 47 or 48. Today it was 37. I will be interested to see how long it takes to "learn" what a more accurate prediction would be. Of course the temperature was down near 40 F with a cold rain falling so the lights, wipers, and heater/defroster were on a lot today so it was not a stellar day for EV milage.

The other interesting thing was that they had to re-home the tire sensors since the software upgrade apparently got those confused...but only on the driver's side tires.....

No the reflash merely reset your statistical baselines. Providing conditions (TTT) remain the same your range estimates will certainly return to whatever they were before.

I think we are actually saying the same thing. :)

BTW, congratulations. The last time I looked, you were a moderator; now you are a Super Moderator! I always thought you were super. ;)

And the difference between a Super WOT and a regular WOT? Several thousand Volts!

Heh, heh, heh.....thanks for all you do.

USB problem attributable to the software update?

OK, so now it's been about three weeks since I had the software update. I've noticed no change in the car whatsoever and I didn't think at first that this had anything to do with the update but, I've now tried four different USB flash drives to transfer music to my HDD. Two of these were the same that I had been using previously and not one of the four now work. In every case I'm presented with the display, "This media cannot be used".
I know the USB port itself still works as the system recognizes my iPhone when plugged in.

There is another thread following USB flash drive problems but I'm wondering if anyone else has noticed this (or any other issue) since the update?
 
What do I gain and what do I lose with this upgrade? Is it ready for prime time yet? I havn't had my car to the dealer in 8 months so I have the original program. My biggest gripe is the dumb a_s input screen for nav, give me a qwerty keyboard.

In the Volt, you only need one "key" to enter an address: the blue one overhead.

Good point, but being a guy that doesn't like to ask for directions I still want a QWERTY keyboard!

I agree, the address entry isn't very good. That's why I use Google Maps or my phone to locate an address and send it to my Volt. And, I can do this ahead of time without even being in the car.
