Not that I'm aware.
Needed to swap the ring on the high voltage connector with the appropriate part for the v2.0 packs going into the v1.x pack cars. Software. Suspension upgrade.
On a side note, I'll eventually get back to offering trade-up type pack upgrades. Right now, at the best price possible, to do 85/90 to 100 is just too expensive for folks to be reasonable, easily over $20k with the 90-pack core. Can technically upgrade any S/X to 100, with 14 module packs being worth less for a core.
60,70,75 to 85 is reasonable, around $12k right now, although 75->85 isn't enough of a range bump to be useful.
14 module packs (40,60,70,75) to 16 module packs (85,90,100), or any pack to 100 requires suspension upgrades if the car doesn't have air suspension.
