Chip tuning for Mercedes CLK 270 CDI (2.7) 170 hp ECU
Mercedes CLK (2003 - W209) 270 CDI (2.7) 170 hp — premium diesel 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 170 to 200 hp (+30 hp, +18%) and torque from 370 to 450 Nm (+80 Nm). ECU — Bosch EDC15C6. Flashing method: OBD or Bench depending on the unit's protection. Diesel engines built in 2003 — the era of classic Common Rail without strong encryption.
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 diesels have long been known for legendary reliability, with German taxi fleets running to million-kilometre mileages. Mercedes pioneered CDI (Common-rail Direct Injection) technology on passenger-car diesels, in series production since 1997. Mercedes diesels have long been popular with the German police and taxi services.
In the Mercedes commercial segment, Stage 1 focuses on torque. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. 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 community is active in Europe, with a large pool of available Stage files. Mid-range Mercedes engines are a premium segment with a conservative factory calibration, and Stage 1 preserves engine life. Mercedes prioritises smooth running, and Stage 1 preserves the engine's character. The Mercedes factory calibration allows a confident move to Stage 1 without hardware changes.
