RS3 (8Y) MG1CS163 ECU Now Unlocked by AutoTuner!



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!

Step-by-step removal tutorial

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.

Details:
  • ECU: Bosch MG1CS163 (HW80)
  • Read: AWS + Calibration (Bench NR 2 min, OBD VR)
  • Write: OBD (Tool & One, 2 min), Bench (Tool, 1min)
  • Backup: Bench
  • Back to stock: OBD
  • OBD Port: Unlocked and unrestricted*
  • Checksums: Automatically Corrected
  • Vehicles: Audi RS3 2.5T (8Y.1), Cupra Formentor VZ5 2.5T (KMA)
  • Optional Hardware: Plug-and-Play Bench Harness

    The OBD port is fully unlocked with no restrictions. We do not limit tuner access. However, compatibility with all third-party tools cannot be guaranteed. Please consult your tuner for confirmation

There's a new way to tune and flash an Audi RS3 (8Y) and it's with the AutoTuner One. RS3 owners will purchase the One from their tuner, bundled with a tune, and will flash their vehicle with their smartphone with the MyFlasher App.

The device supports flashing both Application Software and Calibration sectors enabling tuners to write advanced features such as map switching, flex fuel, rolling anti-lag, and anything else they can dream up.

Pricing on the device is extremely competitive giving tuners the ability to expand their businesses and reach new customers all across the world with their off the shelf or custom tunes. It even includes a convenient cloud interface for the tuner, and requires no subscriptions or credits. Everything is unbranded, so tuners can fully make it their own.
