I'm curious how you know this? Have you tried it? I would have expected the soft coding to change the software it uses, not simply deactivate the TCU.

It is mechanically identical, even down to the injectors. The S6 has a second solenoid attached to the front of the manifold which activates something off the engine, but it still has a single-stage flap activation. The difference in power output is purely software.

The electric fan is probably a separate circuit, the same as the S8 and B5.
