Chip tuning for Mercedes R 350 (3.5i) 272 hp ECU
Mercedes R (2005) 350 (3.5i) 272 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 272 to 295 hp (+23 hp, +8%) and torque from 350 to 380 Nm (+30 Nm). This engine ships with different ECU variants: Bosch ME9.7, Bosch MED17.7.5. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A petrol engine built in 2005 — 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'). 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.
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. 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.
