Chip tuning for Mercedes SLK 300 (3.0i) 231 hp ECU
Mercedes SLK (2004 - R171) 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 2004 — the era before widespread firmware encryption, OBD flash without complications.
AMG is the performance division of Mercedes (since 1967), building engines on the 'one man, one engine' principle in Affalterbach. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Maybach is Mercedes's ultra-luxury sub-brand. On older-generation Mercedes petrol engines, Stage 1 is flashed over OBD without Bench. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships. Mercedes encryption is among the toughest in the industry, especially on modern 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. 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. 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. High-output Mercedes engines are premium-class with solid headroom for Stage 1.
