Chip tuning for Mercedes ML 420 CDI (4.0) 306 hp ECU
Mercedes ML (2005 - W164) 420 CDI (4.0) 306 hp — premium diesel 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 306 to 350 hp (+44 hp, +14%) and torque from 700 to 810 Nm (+110 Nm). ECU — Bosch EDC16CP36. Flashing method: OBD or Bench depending on the unit's protection. The 2005 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.
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 Mercedes three-pointed star symbolises dominance on land, at sea and in the air. Mercedes diesel engines are fitted to passenger cars and commercial vehicles. BlueTEC is Mercedes's proprietary exhaust after-treatment system with an SCR catalyst and AdBlue. High-output Mercedes diesels are premium-class with an emphasis on torque, and Stage 1 is especially felt in Nm.
In the Mercedes commercial segment, Stage 1 focuses on torque. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. 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. The Mercedes premium segment is a high-output platform with Stage 2 potential.
