#192 - Red - San Rafael, CA

If you figure the stated 20 percent loss of range for 100,000 miles that means owners who are at 50,000 miles should be a 10 percent down in range. (if linear) I'm at 44,000 but can't tell my losses accurately since the various firmware changes have dropped my range so much I don't know where I am in relation to when I bought new.

As i remember when new, I would get 192 miles showing in Standard and 238 in Range, Now it's about 182 S (on a good day) and 228 R. Again many firmware changes dropped my range when I charged the day after getting the car back.

Probably not much use to you. I guess I just wanted to vent.

Eric, what firmware versions and what changes did you make if any when you began to see your range being adversely affected? I'd like to compare with mine and see.

My roadster was produced in April 2009, has 4200 miles and I get 190 on a standard charge. When its done charging it will then settle down to 188-189.

The last firmware was updated by Tesla in Jan 2012.

Here's the history of my firmware updates:

timestamp, firmware version
04/15/2009 18:03:25, 3.2.16 12
06/11/2009 09:59:50, 3.3.1 12
10/07/2010 15:59:30, 3.5.18 12
01/26/2012 11:39:54, 3.6.7 12

Also have you been saving off your logs since you owned your car? If so you should be able to use excel or a plotting program against time SOC over time and mark the dates you're firmware was flashed. You then could correlate the updates to the drop in SOC.

Lastly when have you last balanced your pack? This I read can occur when the roadster is in storage mode. I believe you need to charge it full up to standard mode and let it sit for some time (this cycle has to be repeated 2 to 3 times). I don't know if you need to pull the pack down to any specific range though.

I'm at 22k and about 4% down from when I got the car so the 20% at 100k is about right assuming everything is linear...

Eric,....

The car is older than any of the user generated readers so I was not keeping logs. Not really a logger type person. Talk to Tom Saxton and a few others here. The only changes I made when presented with less mile was to drive shorter distances.

Looks like the EBay auction expired with max offer of $72k not taken.

How can you tell that the max offer was $72K, I don't see that info anywhere?
