Hello everyone,

I have a VW Passat B6 3.2 VR6 (AXZ engine code) and I’m planning to do a supercharger build.

For engine management, I want to use an ECUMaster EMU Black.

My main concern is communication between the EMU Black and the DSG gearbox.

I’m trying to understand what the correct approach is:

- Should I completely remove the original OEM ECU and run the car only on EMU Black?

- Or is it better to keep the OEM ECU installed (for CAN/DSG communication) and run EMU Black in parallel to control the engine?

Unfortunately, in my area there is no experienced tuner or workshop that has done EMU Black + DSG setups, so I’m trying to figure this out on my own. I’m still a beginner in this specific topic and would really appreciate advice from people who have actually done this in real cars.

Any guidance, real-world experience, or best practices would be greatly appreciated.

Thank you very much in advance.
