My observation from 7P ACC DeFit:

Warnings!!!​

  • Possible instrument cluster fuckups - DO NOT TRY TO CODE INSTRUMENT CLUSTER!. Got checksum error once. Luckily managed to fix it with special tools.
  • Instrument cluster does not show CCS speed and state (may be some coding or smth)
  • Some modules will have error codes

Physical modifications​

Remove SC49 fuse from drivers side fuse box (acc fuse)
