Chip tuning for Mercedes CLS 450 AMG (3.0T) 367 hp ECU
Mercedes CLS (2018 - C257) 450 AMG (3.0T) 367 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 367 to 410 hp (+43 hp, +12%) and torque from 520 to 600 Nm (+80 Nm). This engine ships with different ECU variants: Siemens/Continental CPC_NG, Bosch MED17.7.3.1, Bosch MG1CP002, Bosch VGS3-NAG3, Siemens/Continental VGS4-NAG2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 5 configurations · 5 ECU variants. A modern petrol engine built in 2018 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.
Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. 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. Top AMG engines offer significant potential with a downpipe + intake. AMG is Mercedes's performance division (since 1967), acquired by Mercedes in 1999. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships.
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. The Mercedes community in Europe has a large pool of available Stage files for the standard models. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant. AMG engines are a well-known base once hardware is added (downpipe + intake + intercooler). Brabus is a premium alternative to AMG for the top models. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects.
