Chip tuning for Mercedes CLS 350d 252 hp ECU
Mercedes CLS (2010 - C218) 350d 252 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 252 to 300 hp (+48 hp, +19%) and torque from 620 to 700 Nm (+80 Nm). This engine ships with different ECU variants: Bosch EDC17CP57, Siemens/Continental VGSx-NAG2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A diesel built in 2010 — the Tricore ECU era; OBD flash works on most production revisions.
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. 4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. 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. The factory calibration on Mercedes diesels is conservative, leaving headroom for Stage 1 while preserving engine life.
In the Mercedes commercial segment, Stage 1 focuses on torque. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. 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.
