By | April 30, 2026

A monumental update has arrived on your AutoTuner Tool! You have been waiting for it: we are extremely proud to announce the highly anticipated support for the locked Bosch MG1CS163 ECUs (latest security updates), which manage the most extreme versions of the legendary 2.5 TFSI (5-cylinder) engine in their Pre-facelift configurations.

One Integration: Boost your sales! This compatibility extends to our end-user tool, the One. Once the initial unlock is completed, you can sell your tunes remotely. Your customers will be able to flash their RS3 or Formentor VZ5 directly from home via the OBD port!

  • Cupra Formentor VZ5 Gen1 (2020) – 2.5 TSI VZ5

Method: Bench & OBD (After Mail-in Unlock). This protocol requires the ECU to be sent to our facility first. Great news: The OBD Unlock will be performed directly by our team during this internal unlock process. Even better, if the vehicle receives a dealer update later on, you will be able to perform this OBD Unlock directly using the Tool in Bench !

Major Technical Feature (ASW + Calibration): For the first time, and to meet our users’ expectations, the VR (Virtual Read) file resulting from the OBD Unlock now includes both the calibration and the ASW. This evolution allows you to fully exploit advanced features such as high-speed logging or map switching, options particularly sought after by demanding tuners.
