Audi RS4 (B9) Bubbling only in dynamic mode ECU rewritten
Audi RS4 (B9) bubbling installation, can be set by rewriting the ECU.
The engine is a 2.9L V8 twin turbo with up to 450 hp. (This time the ECU has been rewritten without any power increase, but in normal Stage 1 the engine makes 60 hp/180 Nm more.) Previously, the bubbling was sounded in all modes, but this year it has been found out how to make it bubbling only in dynamic mode. This time the RS4 is also bubbling in dynamic mode only.
Use AutoTuner to read the data, create and install a bubbling map for your vehicle.
Installation can be done in approximately one hour. In case you are wondering, the bubbling does not sound all the time in this generation of Audi in particular, but after a certain amount of bubbling, the bubbling stops, perhaps to protect it. The bubbling can then be heard after a while.
