This car is so locked down we can't even manage TPMS, much less an ECU.

Amen. I'd be happy just to be able to fix TPMS myself. On my next tire purchase I'm going to buy four new sensors, document the numbers on them, and have to visit the dealership just to get those numbers programmed in the ECU. Thats pretty freaking locked down if you ask me.
