Chip tuning for Mercedes CLS 320 CDI (3.0) 224 hp ECU
Mercedes CLS (2004 - C219) 320 CDI (3.0) 224 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 224 to 255 hp (+31 hp, +14%) and torque from 510 to 600 Nm (+90 Nm). This engine ships with different ECU variants: Bosch EDC16C2, Bosch EDC16CP31, Bosch EDC17CP01, Siemens/Continental VGSx-NAG2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 4 configurations · 4 ECU variants. The 2004 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.
Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Maybach is Mercedes's ultra-luxury sub-brand. Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. Mercedes diesels are known for smooth, quiet running, a hallmark of the premium segment. Mercedes diesels have long been known for legendary reliability, with German taxi fleets running to million-kilometre mileages. Mercedes pioneered CDI (Common-rail Direct Injection) technology on passenger-car diesels, in series production since 1997.
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. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. 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.
