My 2020 M2C's ECU is locked, and with the CS's coming out, the ECU will eventually be unlocked without bench flashing. When that happens, I will likely be flashing the M3/M4 CS tune to my car.

I have been seeing posts about the "locked" vs. "unlocked" ECUs, which I don't have any context around. What does that mean, exactly? I was under the assumption that this ship had sailed for the S55.
