Tesla Uses Engineering Samples for the Modem in All the New Model S, 3, and Y Units

According to GreenTheOnly – a white-hat hacker that has studied Tesla products and software for years – all units of the Model S Plaid and all Model 3s and Model Ys with AMD chips come with modem chips that read “engineering sample.” The hacker was told that this was a way to include radio equipment that has not yet passed the necessary FCC certification in production vehicles.

“What chip shortage?” ?

Huh, radio equipment that does not pass FCC standards is not legal for sale to consumers. That said, only the chips are in question here. If the assembled system has been tested and shown to meet or exceed (meeting the standard is not desirable, as individual examples of the same technology may perform worse) the FCC standards, the system manufacturer may self-declare compliance And therefore sell the system to consumers. ?‍??

Well. That is downright freaking …..

PLAID.

I am waiting for this word to appear as a Wordle

Jes sayin.

I don't believe entire cars have an FCC ID (do they?), it seems just the circuit board modules. The one thing though is the engineering samples may be different than future production boards.

It’s probably the subsystem that has a self-declaration. I doubt that anyone is going through the machinations to get an FCC ID for subsystems like these when they can test, document, and self-declare. ??

As I read it (maybe I read it wrong), the chips are the engineering samples and Brand T is building a subsystem around the chips. Perfectly fine and legal for them to do this, test, document, and self-declare. If the production chip is functionally and physically identical to the production samples, they are fine (I have pre-certified a lot of different products using preproduction chips). What would not be legal is if the production chips required changing the PC board layout in a significant manner and they did not test, document, and self-declare for the new layout. As long as they are within limits with margin, they are perfectly fine. ??
