Chip tuning for Mercedes Citan 108 CDI (1.5) 75 hp ECU
Mercedes Citan (2012 - W415) 108 CDI (1.5) 75 hp — premium diesel 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 75 to 110 hp (+35 hp, +47%) and torque from 180 to 240 Nm (+60 Nm). ECU — Bosch EDC17C42. Flashing method: OBD or Bench depending on the unit's protection. A diesel built in 2012 — the Tricore ECU era; OBD flash works on most production revisions.
The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). 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. Mercedes diesels have long been popular with the German police and taxi services. Mercedes diesel engines are fitted to passenger cars and commercial vehicles. BlueTEC is Mercedes's proprietary exhaust after-treatment system with an SCR catalyst and AdBlue.
The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. 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. In the Mercedes city segment, Stage 1 is more about comfort and responsiveness than power. On low-output Mercedes engines, Stage 1 is safe and does not over-stress the hardware. On naturally aspirated Mercedes engines without a turbo, the main effect is on throttle response.
