Chip tuning for Mercedes ML 500 (5.5i) 388 hp ECU
Mercedes ML (2005 - W164) 500 (5.5i) 388 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 388 to 408 hp (+20 hp, +5%) and torque from 530 to 570 Nm (+40 Nm). ECU — Bosch ME9.7. Flashing method: OBD or Bench depending on the unit's protection. In the CHIPOK database: 2 configurations. The 2005 generation — old-era petrol ECUs (ME7/ME9/MED9/Simos) with easily readable memory.
The Mercedes three-pointed star symbolises dominance on land, at sea and in the air. 4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. The Mercedes-Benz Group AG (Daimler AG until 2022) comprises Mercedes-Benz, AMG, Maybach, Smart and the EQ line. Mercedes encryption is among the toughest in the industry, especially on modern models. Top AMG engines offer significant potential with a downpipe + intake. AMG is Mercedes's performance division (since 1967), acquired by Mercedes in 1999.
Stage 1 on Mercedes often requires refreshing the adaptations after the flash. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The Mercedes community in Europe has a large pool of available Stage files for the standard models. Bench reading is a mandatory procedure for modern AMG models. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant. AMG engines are a well-known base once hardware is added (downpipe + intake + intercooler). Brabus is a premium alternative to AMG for the top models.
