See my other post on the battery fault thread. My very recent update to the PCM has greatly improved the range. I suspect this is mostly the regen recall update, but could also be addressing the phantom battery fault that shut down everything. I went from a range of 201 mi that dropped to the 180's, but now it is showing a range of 261 miles. It looks like my average efficiency is about 2.8 mi/kwhr now, whereas before it was below 2 most days. Again, I believe this has to do with the regenerative braking update.
