Mercedes ML (2011 - W166) 350 BlueTec (3.0) 258 hp — premium petrol engine of the passenger segment of the Mercedes-Benz Group AG (Mercedes-Benz, AMG, Maybach, Smart, EQ) group (Германия, 1926). Stage 1 chip tuning raises power from 258 to 300 hp (+42 hp, +16%) and torque from 620 to 700 Nm (+80 Nm). This engine ships with different ECU variants: Delphi CPC2, Bosch DCU17PC01, Bosch EDC17CP10, Bosch EDC17CP46, Bosch EDC17CP57, Siemens/Continental VGS4-NAG2, Siemens/Continental VGSx-NAG2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 7 configurations · 7 ECU variants. A petrol engine built in 2011 — a Tricore platform without strong protection; OBD access works.
The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). Smart is Mercedes's city sub-brand, historically running Mitsubishi and Renault engines. Karl Benz is credited as the inventor of the automobile with the 1886 Patent-Motorwagen. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1. High-output Mercedes turbo petrol engines are the flagship models, and Stage 1 delivers a solid gain. Mid-generation petrol models use standard OBD flash.
The Mercedes community in Europe has a large pool of available Stage files for the standard models. On Mercedes up to the recent generation, Stage 1 OBD flash is available. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. The Mercedes premium segment is a high-output platform with Stage 2 potential. High-output Mercedes engines are premium-class with solid headroom for Stage 1. On modern high-output Mercedes, Bench reading is often required because of the encryption.
