When the 2.5 TFSI “DAZA” in the RS3/TTRS (8V/8S) hit the scene, it took the tuning market by surprise. Naturally, the next-generation RS3 (8Y) and Formentor VZ5 had everyone ready for more. Then reality hit. The extreme encryption on the Bosch MG1CS163 (HW80) ECU mostly shut the door on tuning with only expensive and complicated workarounds… Until now.

Starting today you can unlock your ECU with our Mail-in Unlock program, right here in the USA, and flash the ECU with the AutoTuner Tool and the AutoTuner One!

All new ASW + Calibration Virtual Read Support
For the first time ever, our Virtual Read now includes both the ASW and Calibration allowing advanced tuners to create their own custom features such as high-speed datalogging, map switching, flex-fuel, and other function often demanded by clients on this platform.

The process is simple, quick, and inexpensive:

• Order our mail-in unlock.
• Mail us the ECU at at UPS access point with the included next-day air shipping label.
• Reinstall your Unlocked ECU and start tuning! We'll send it back via next-day air.

We unlock ECUs the same day we receive them. There’s no physical modification to the ECU, and typically the whole process, including shipping both ways, takes under 48 hours. And if the ECU is ever locked again, you can unlock it in the field with the Tool.
