Chip tuning for Mercedes E 500 (5.5i) 388 hp ECU
Mercedes E (2009 - W212) 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 2009 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. 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. On older-generation Mercedes petrol engines, Stage 1 is flashed over OBD without Bench.
AMG engines confidently reach Stage 2 with a downpipe + intake. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. 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.
