Chip tuning for Mercedes S 300 (3.0i) 231 hp ECU
Mercedes S (1997 - W220) 300 (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 1997 — the era before widespread firmware encryption, OBD flash without complications.
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. The Mercedes community in Europe has a large pool of available Stage files for the standard models. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. 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.
