This engine ships with different ECU variants: Siemens/Continental CPC_NG, Bosch MG1CP002, Bosch VGS3-NAG3. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 3 configurations · 3 ECU variants. A modern petrol engine built in 2021 — a generation with encrypted ECU protection (Tricore TPROT); top engines require Bench.
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'). Smart is Mercedes's city sub-brand, historically running Mitsubishi and Renault engines. 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. Modern AMG engines are heavily encrypted, so Bench reading is mandatory.
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. The Mercedes community in Europe has a large pool of available Stage files for the standard 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. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects.
