Bosch M17.8.4

New AT Protocol!

Dear Users,

We are expanding our vehicle coverage to new horizons! The Bosch M17.8.4 ECU, found in the famous Tata Nano city car, is now fully supported on your AutoTuner Tool.

Even though the Nano is one of the most compact cars on the market with its tiny 0.624L engine, it still benefits from optimization! Whether you need to make specific map adjustments, improve drivability, or cater to international market requests, you now have the perfect solution.

⚡ Methods: 100% OBD & Bench (Normal Read - NR) Enjoy maximum flexibility for your tuning jobs! You can read and write this ECU directly through the diagnostic port (OBD) for ultimate time-saving, or work via Bench on your desk depending on your preference and workflow.

Supported Vehicle & Engine:
