Chip tuning for Mercedes CLS 450 AMG (3.0T) MHEV 367 hp ECU
Mercedes CLS (2018 - C257) 450 AMG (3.0T) MHEV 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 500 to 580 Nm (+80 Nm). This engine ships with different ECU variants: Bosch MG1CP002, Bosch VGS3-NAG3. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A 2018 petrol engine — the latest era of encrypted firmware; OBD access is available on production units, Bench on sport models.
4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. The Mercedes-Benz Group AG (Daimler AG until 2022) comprises Mercedes-Benz, AMG, Maybach, Smart and the EQ line. AMG is the performance division of Mercedes (since 1967), building engines on the 'one man, one engine' principle in Affalterbach. Modern AMG engines are heavily encrypted, so Bench reading is mandatory. The AMG 'one engineer, one engine' principle means each engine is built by a single craftsman whose signature appears on the plaque. Maybach uses Mercedes engines for the ultra-luxury segment, with the emphasis on quietness and smoothness.
AMG engines confidently reach Stage 2 with a downpipe + intake. 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. 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.
