Chip tuning for Mercedes C 350 BlueEFFIENCY (3.5i) 306 hp ECU
Mercedes C (2010 - W204) 350 BlueEFFIENCY (3.5i) 306 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 306 to 330 hp (+24 hp, +8%) and torque from 370 to 400 Nm (+30 Nm). This engine ships with different ECU variants: Bosch MED17.7.1, Bosch MED17.7.3, Siemens/Continental VGSx-NAG2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 3 configurations · 3 ECU variants. A petrol engine built in 2010 — a Tricore platform without strong protection; OBD access works.
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. Mercedes encryption is among the toughest in the industry, especially on modern models. Maybach uses Mercedes engines for the ultra-luxury segment, with the emphasis on quietness and smoothness. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1.
Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The Mercedes community in Europe has a large pool of available Stage files for the standard models. On Mercedes up to the recent generation, Stage 1 OBD flash is available. 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.
