Chip tuning for Mercedes CLS 350 CGI (3.5i) 292 hp ECU
Mercedes CLS (2004 - C219) 350 CGI (3.5i) 292 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 292 to 312 hp (+20 hp, +7%) and torque from 362 to 390 Nm (+28 Nm). ECU — Bosch ME9.7. Flashing method: OBD or Bench depending on the unit's protection. The 2004 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. 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. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships.
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. 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.
