    Wiki Sudden Loss Of Range With 2019.16.x Software

    Yeah, imho the most helpful is all the info provided by @wk057 in the various threads he is contributing, most notably these two posts: https://teslamotorsclub.com/tmc/threads/supercharging-speeds-who-what-where-why-and-when.225443/page-3#post-6079805...

    Wiki Sudden Loss Of Range With 2019.16.x Software

    Hey! End of last year I've upgraded to 2020.48.37.8 from 2019.12.1.1 since I was scheduled to replace the 12V battery and the tegra board. Not having planned to drive much I even updated to 2021.24.28 5th March and stuck to it until early April. Then two bigger trips were planned and before...

    According to Tesla SeC a downgrade is not possible. Since it is security related, any discussion in the past to this matter was purged from open forums. I will not provide content which will violate the security and thus force the mods to taking action. Thanks for your understanding!

    I've succesfully charged with CCS on two different chargers after the downgrade. 1) The aforementioned ABB 50kW functions with both the CHAdeMO and the CCS adapter, same behavior and in lower %soc the kWh is limited through the voltage of the battery and the max output current. When the %soc...

    I've recently had to update to 2020.36.11 for getting the CCS update via ranger, afterwards another visit at a SeC to fix unlocking/start/etc. via app (*). Then a downgrade straight back to 2019.12.1.1 to get the max brick voltage cap and the charging rate taper removed. Diagnostic Mode of MCU...

    Wiki Sudden Loss Of Range With 2019.16.x Software

    Hi! No range back in reality, but with 2020.36.11 it seems that theoretically I would get 208mi/335km at 100% shown as typical range. So it seems to me, the typical range calculation adopted to show more without actually increasing capacity. I've driven with 2019.12.1.1 until a couple of weeks...
