Bosch MG1CS623

New AT Protocol!

Dear Users,

A new era begins for the Japanese giants! We are extremely proud to announce that the brand-new Bosch MG1CS623 ECU is now officially supported on your AutoTuner Tool.

This protocol grants you exclusive access to the absolute latest generation of luxury and off-road SUVs from the Nissan/Infiniti group (2024-2025 models). Say goodbye to the V8, and hello to the brand-new, hyper-powerful 3.5L Twin-Turbo V6 engine! You now have the perfect solution to boost the massive torque required by these heavyweights, including the highly exclusive Nismo variants.

🔒 The secure workflow (Mail-in ➡️ Bench): To guarantee absolute safety on these latest-generation ECUs, an initial unlock is required:

Mail-in Unlock: The ECU must first be sent to our facility for a highly secure unlock by our engineers.

Bench: Once the ECU is returned to your shop, you have total control to comfortably read and write the vehicle via Bench.

Exclusive Supported Vehicles (3.5T V6 Engine):

Nissan: Patrol & Armada (2024-2025) – Including Nismo versions!
Infiniti: QX80 (2025)

Stay ahead of the curve and be the first to tune the new kings of the desert and the road!
