If I plug in with a J-1772 adapter with 80 amps will the M3 ramp up to 80 amps?

[Villa-Lobos]

I plug into my garage with a 14-50 but only get 32 amps. With a J-1772 plug in a 80 amp power source will the Model 3 get to 80 amps or top out at 32 amps?

No. It'll max out at either 32 or 48 amps: Onboard Charger. This also depends on the EVSE itself. You need to connect to at 48+ amp L2 EVSE to hit 48 amps.

See Three Things Determine EV Charge Time for background info.

The Model 3 SR+ can charge at a max of 32 amps. The LR models can charge at up to 48 amps. Note that the mobile charger that comes with the car maxes out at 32 amps.

And, the mobile unit isn't a charger. It's an EVSE and Tesla in particular calls it Mobile Connector.

For L1 and L2 AC charging, the external unit is an EVSE. The charger is on-board the car.

I think this isn't a distinction that needs to continuously be reiterated. While it's technically correct and I used to remind folks all the time, I can't help but feel like it's a bit pedantic to say. We still call the cord that is used to charge our cell phones "the phone charger" when the actual charging circuitry is internal to the phone.
