Then why does Elon keep dangling this?
Because I truly believe he thinks it's possible, or at one time "MCU1 Retrofit" was on the original list or requirements, and that never came to be reality. Or his engineers are saying it's not possible/feasible, and he says nothing is impossible and still believes it can happen. But the cost and payback for Tesla just doesn't make sense no matter how you cut it. I think there would be such a small number of people who would request and pay for such an upgrade. The number on TMC is huge, but the number of the general Tesla population? Tiny. I think most people don't know or don't care about the differences. Just go by how many people you run into at superchargers that don't know about the A/B pairing? (most people, in my experience). They're not going to be requesting or demanding an MCU retrofit.
@HankLloydRight I've assumed that MCU2 could still drive the old IC over the bus. May limit features. I would think an integrated IC controller could facilitate displaying video on the IC. Any chance of this? Also, old antennas would still work if they simply disabled 5ghz WiFi.
I wouldn't assume anything! If the processing for the IC was moved from the MCU1-IC to onboard MCU2, I'm not sure that MCU2 would still be able to send the old signaling to an old IC. That just seems like a Frankenstein/hybrid system that would never be supported in the firmware (without major hacking).
