Were you expecting a virtual TMS ? Or a software installed Tesla pack ? In the best possible scenario, your pack is degrading at a rate we expect from a 24 kWh "lizard" pack in Texas.
I'm skeptical that this is the case and that the update gave you ~ 5 kWh of extra battery capacity, but if true I would say that is awesome.

“I was at 8 bars, 50.4 AHr, 63.41% SOH, prior to the update.”

Jbuntz, sorry if I missed your explanation somewhere earlier, but if you were at 8 bars didn’t you qualify for a new battery? Were you required to do this SOftware downgrade (I mean Upgrade :o )

I’m sure he was. With the old LEAF battery, you were required to have the BMS update more than six months prior to getting your battery replaced.

jbuntz, please let us know what your LeafSpy reports over the next month or so.

Sorry for not being more explicit. Your comment is right on, i.e. the update is basically a joke!
I think I've expressed/implied that before on this thread and the other one. Nissan basically
just reduced their near term liability for warranty battery replacements on the 30kWh Leaf
with the update.

The $1000 question in my mind is whether range increased. If so then Nissan also benefits but I would not hold that against them in any way. It would be unusual though; I am used to seeing Nissan benefit at the customer's expense.

Roger that, but my letter from Nissan stated this was a “Voluntary” SW Update. It did not state it was a requirement. And did not mention any affect on the warranty coverage.

There was no cut off. The reality is Nissan was getting degraded packs and upon testing, they were well over the 8 bars required for replacement so the people who did get new packs, got them thru a Nissan SW error. not from true degradation.
