Chip tuning for Mercedes CLK 500 (5.0i) 306 hp ECU
Mercedes CLK (2003 - W209) 500 (5.0i) 306 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 306 to 326 hp (+20 hp, +7%) and torque from 460 to 485 Nm (+25 Nm). ECU — Bosch ME2.8. Flashing method: OBD or Bench depending on the unit's protection. The 2003 generation — old-era petrol ECUs (ME7/ME9/MED9/Simos) with easily readable memory.
Smart is Mercedes's city sub-brand, historically running Mitsubishi and Renault engines. 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. 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. High-output Mercedes turbo petrol engines are the flagship models, and Stage 1 delivers a solid gain.
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 community in Europe has a large pool of available Stage files for the standard models. 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.
