Chip tuning for Mercedes CLS 550 (4.6i) 402 hp ECU
Mercedes CLS (2010 - C218) 550 (4.6i) 402 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 402 to 430 hp (+28 hp, +7%) and torque from 443 to 473 Nm (+30 Nm). ECU — Bosch MED17.7.1. Flashing method: OBD or Bench depending on the unit's protection. The 2010 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.
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. Brabus is an independent Mercedes tuning house specialising in top-model upgrades. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1. Mid-generation petrol models use standard OBD flash.
The Mercedes community in Europe has a large pool of available Stage files for the standard models. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. On Mercedes up to the recent generation, Stage 1 OBD flash is available. Brabus is a premium alternative to AMG for the top models. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects. Bench reading is a mandatory procedure for modern AMG models. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant.
