New AT Protocol!
Dear Users,
An exceptional update has arrived to reshape the performance landscape of the ultra-premium segment! We are thrilled to announce that the state-of-the-art Bosch MG1CS221 ECU is now officially supported on your AutoTuner Tool.
This high-end protocol targets the absolute pinnacle of modern German and British engineering: the mighty 4.4L Twin-Turbo V8 powerplant. This latest-generation architecture doesn't just drive the heavy hitters of the BMW M Power lineup (New M5, XM, X5 M) and the refined M60i MHEV range—it also powers the most exclusive, flagship configurations from Land Rover, including the majestic Range Rover SV (P615/P635) and the radical, high-performance Defender OCTA (2024+)!
🔒 Advanced Workflow (Mail-in ➡️ Bench):
-
Mail-in Unlock: The ECU must first be sent to our headquarters for a secure hardware unlock by our specialized engineering team.
-
Bench: Once returned to your shop, software restrictions are gone. You gain unrestricted Bench access to safely read and write calibrations.
