New AT Protocol!
Dear Users,
Today, we are deploying a software update of monumental proportions. We are thrilled to announce full Bench mode support for a massive wave of latest-generation Bosch ECUs powering the modern Mercedes-Benz lineup: MG1CS046 (MRG3), MG1CS100 (MRG2), MD1CP010 (MRD2.20), and MD1CP011 (MRD2.1) on your AutoTuner Tool!
This colossal release targets the absolute core of the recent German car market (2020 to 2025+ models). It covers almost all modern Petrol and Diesel drivetrains paired with Mild-Hybrid (MHEV) and Plug-in Hybrid (PHEV) systems—spanning from the everyday C-Class to the iconic G-Class and ultra-luxurious Maybach variants.
🔒 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 restrictions are gone. You gain full Bench access to read and write calibrations directly on your workbench with total peace of mind—no ECU opening required.
