Chip tuning for Mercedes E 350 (2.0T) MHEV 299 hp ECU

Mercedes E (2016 - W213) 350 (2.0T) MHEV 299 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 299 to 328 hp (+29 hp, +10%) and torque from 400 to 450 Nm (+50 Nm). This engine ships with different ECU variants: Siemens/Continental CPC_NG, Bosch MED17.7.7, Bosch VGS3-NAG3. 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 2016 — a Tricore platform without strong protection; OBD access works.

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. The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). 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.

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 community in Europe has a large pool of available Stage files for the standard models. 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.
