Chip tuning for Mercedes SLK 250 CDI S&S (2.1) 204 hp ECU
Mercedes SLK (2011 - R172) 250 CDI S&S (2.1) 204 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 204 to 240 hp (+36 hp, +18%) and torque from 480 to 550 Nm (+70 Nm). This engine ships with different ECU variants: Delphi CRD3.58, Bosch EDC17CP46, Bosch EDC17CP57, Bosch EDC17CP60, Siemens/Continental VGSx-NAG2, Delphi CRD3. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 6 configurations · 6 ECU variants. A diesel built in 2011 — the Tricore ECU era; OBD flash works on most production revisions.
Maybach is Mercedes's ultra-luxury sub-brand. Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. The Mercedes slogan is 'Das Beste oder nichts' ('The best or nothing'). Mercedes diesels have long been known for legendary reliability, with German taxi fleets running to million-kilometre mileages. Mercedes pioneered CDI (Common-rail Direct Injection) technology on passenger-car diesels, in series production since 1997. Mercedes diesels have long been popular with the German police and taxi services.
In the Mercedes commercial segment, Stage 1 focuses on torque. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The AMG community is active in Germany, but the protection is the toughest in the industry, so Stage 1 on AMG usually requires Bench. 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.
