FYI…
Currently, Xtool D7, D8, D9, D9 Pro can do CanFD, even 2023.
Xtool D8 and D9 can work alone, but D7 needs a different cables and Xtool CAN FD adapter.
In addition, Xtool X100 PAD3, A80, A80 Pro will also do this.

Q: Obdstar or xtool d8 for gm or chevy 2021? Which one would you suggest for pin free add key? I have im608 and topdon but none do it without pin.
A: Both rely on servers to get the job done. If one is down, you can use the other one. Autel can’t do these.
