Chip tuning for Mercedes E 250 CGI (1.8T) 204 hp ECU
Mercedes E (2009 - W212) 250 CGI (1.8T) 204 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 204 to 240 hp (+36 hp, +18%) and torque from 310 to 380 Nm (+70 Nm). ECU — Siemens/Continental SIM271DE2.0. Flashing method: OBD or Bench depending on the unit's protection. A petrol engine built in 2009 — the era before widespread firmware encryption, OBD flash without complications.
Karl Benz is credited as the inventor of the automobile with the 1886 Patent-Motorwagen. The Mercedes three-pointed star symbolises dominance on land, at sea and in the air. 4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. 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.
The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. 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.
