I got the firmware this week-end at Branchez-vous 2015 , I saw 2 new sub menu for Mode Button; BTL & BTH both in degree. I guess lowest & highest temp between pack. Probably a lot of subtle improvement by the way.Not sure but I think it was a dash & motor controller update plus one update per pack. it took 45-60 min. after that freebee charge & I tried BMW I3, tesla s 85, cadillac ELR , Kia Soul, Focus, Smart, Electric Motion EM 5,7 Trial and of course a Zero DS. Lito Sora was there but for eyes only so the BMW I8.
