Calibrating BMS with a software locked battery (SR)

[lateulade]

@AlanSubie4Life here’s my TeslaFi data. 6 months and 15k miles in and I was still getting 238 at 100%. The morning the upgrade pushed through, I was down to 209. A few days after that, and I was below 205.

Hmm. Who knows. Maybe you would get 25-29 miles back or so rather than 20.

maybe they are downgrading SRs more than they “should” be

That's exactly what is happening and no matter how you try explain it to tesla service, they always say "no your range is normal" because they can't fix. Only software update could fix it, my opinion.

I think this is accurate — it seems like everyone who downgraded went to 209 overnight

I imagine the reason they don’t do this is that you could easily find yourself in a situation where you decide to upgrade to SR+ but don’t get additional range because degradation had been hidden. I’d be pissed if I paid $1500 and got 2 more miles of range or something.

I would avoid upgrading to sr+ if you are sr owner. I’m at 192-194 at 90% and 216 at 100% that’s over 10% degradation and I only have 35k miles on car..

FWIW, I’m back to 206rmi after dipping as low as ~195rmi
