Yeah, apparently that's the case here too, and I'll be going that route. I just thought it was ridiculous that I'd have to leave the there for a month and probably pay like $1k. Surely they have the equipment to do the transfer, no?

No, they don't usually want to mess with odometers because of the liability. I think most manufacturers require that the cluster is sent to them in order to verify the correct mileage and then program a new one. There's aftermarket tools for doing it on some models, others you can just dump an eprom with a cheap programmer, it just depends really.

That's ridiculous. Here's a decent way to do it:

  1. Desolder the chip (or have a read-only port to plug into) and put it on a test board
  2. Read the chip output and send it to the manufacturer (has mileage plus w/ cryptographic signature)
  3. Manufacturer sends newly programmed chip to the mechanic, and the mechanic sends the old chip back in the provided packaging
  4. Customer gets the car back, and the manufacturer can verify that the chip swap was legit

Boom, under a week turnaround without any backdoors in the odometer.
