New AT Protocol!
Dear Users,
A new high-tech era has just unlocked for Affalterbach's ultimate sports lineup! We are thrilled to announce that the cutting-edge Bosch MG1CP004 (MRG1PI) ECU is now officially supported on your AutoTuner Tool.
💡 Inside the Next-Gen AMG Engineering: This exclusive protocol targets the absolute latest generation of high-performance drivetrains from Mercedes-AMG. Moving away from traditional V6 and V8 layouts on these specific segments, Mercedes introduced advanced, Formula 1-derived engineering. This ECU manages the high-output 2.0L turbocharged platform featuring electric exhaust gas turbochargers, whether paired with Mild-Hybrid tech (43 AMG MHEV) or the blistering 680+ hp Plug-in Hybrid setup (63 AMG S E-Performance).
With this major software release, you now hold the ultimate solution to optimize and refine these highly complex, modern performance weapons!
🔒 Advanced Workflow (Mail-in ➡️ Bench):
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 workshop, factory software restrictions are gone. You gain unrestricted Bench access to safely read and write calibrations directly on your workbench—no physical ECU opening required.
