New AT Protocol!
Dear Users,
The absolute peak of German engineering has just been unlocked! We are thrilled to announce that the latest-generation Bosch MG1CS202 and MG1CS203 ECUs are now officially supported on your AutoTuner Tool.
This exclusive protocol targets the absolute finest of Ingolstadt's sport lineup driven by high-efficiency V6 turbocharged powerplants. From the smooth yet potent 3.0 TFSI powering the brand-new Audi S5 and SQ5 SUV to the fierce 2.9 TFSI Twin-Turbo inside the radical Audi RS5, you now hold the ultimate key to refining their performance curves.
🔒 A Cutting-Edge Workflow (Mail-in ➡️ Bench): To safely bypass the highly sophisticated factory security layers implemented on these brand-new 2025 and 2026 models, a seamless two-step process is required:
Mail-in Unlock: The ECU must first be sent to our headquarters for a secure, high-precision hardware unlock by our engineering team.
Bench: Once returned to your shop, software restrictions are removed. You gain full Bench access to read and write calibrations directly on your workbench with total peace of mind—no ECU opening required.
