Chip tuning for Mercedes C 280 (3.0i) 231 hp ECU
Mercedes C (2007 - W204) 280 (3.0i) 231 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 231 to 250 hp (+19 hp, +8%) and torque from 300 to 330 Nm (+30 Nm). ECU — Bosch ME9.7. Flashing method: OBD or Bench depending on the unit's protection. A petrol engine built in 2007 — 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. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1. High-output Mercedes turbo petrol engines are the flagship models, and Stage 1 delivers a solid gain. On older-generation Mercedes petrol engines, Stage 1 is flashed over OBD without Bench.
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. The Mercedes premium segment is a high-output platform with Stage 2 potential. 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.
