Can I swap HV packs between my cars with the subscription version of Toolbox?

I currently own three Model S's including an S60 I bought with a failed pack. If I have that upgraded to the new 90kWh 1014116-00-C pack at the Service Center, can I swap the pack between that and one of my 85's without help from the SC? I have the public subscription version of Toolbox and the service manual indicates Toolbox 2 will automatically identify the HV replacement HWID and update the gateway. I just don't want to go through all the work swapping the packs only to find out the manual is referring to the SC version of Toolbox 2. All in, after selling the newly working S60 with an 85 battery, this should be the least expensive way to upgrade the pack in my P85DL+ that is almost out of warranty.
 
The download link for Toolbox 2 is in Toolbox 3 now, so I have working access to both.

The gateway unlocks when in Service Mode Plus after a few seconds with my foot on the brake and the right turn signal on.


The service manual shows this:

Interesting. News to me if TB2 is usable now.

I'd try it and see if you can actually use it to change something innocuous, like wheel type or something, before trying the battery. If that works I don't see why you'd have a problem.

Also keep in mind these 350V 90 packs have less power than the P85DL packs, since you're still limited by the motor max current and now have ~13% less voltage (P=V*I). They bump max motor current a bit above what I'd consider sane in these new 350V configs to cover some of the difference (more wear on the inverters at launches or other WOT events), but you're still down about 10% power vs the 400V packs.

Well, it certainly isn't the TB2 that I had as a management level employee. It is dumbed down quite a bit.

When I click the VIN and see the different gateway items, I noticed that more things prompt a contact to Service Engineering than I recall in the SC version. I can change "spoiler", "liftgate strut type", and even car color. However I can't change "Performance", "TPMS type" or "Charger" like I could as an employee. Battery ID is also locked down in that list but that is supposed to change automatically.

This is very crucial information that is making me rethink the idea of buying new 350V 90kWh vs. grabbing a used 400V 100kWh. Thank you!

AS @wk057 notes the top-end power on the 350V packs is definitely lower - well, because physics. The modules in these 350V packs are however able to deliver healthy doses of current without voltage sag. So, when combined with the nearly endless bottom-end torque delivery of any of these packs (the bump in max current is just so unnecessary...), the sustained power on these packs still delivers (as Jack Rickard used to say) a 'spirited' driving experience. ;)

maybe the old adage of "there's no replacement for displacement" in the hydrocarbon world needs something similar in the EV world:

"yardage is all about the voltage" ;)
