Chip tuning for Mercedes GLC 300de 335 hp ECU
Mercedes GLC (2023 - X254) 300de 335 hp — premium hybrid 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 335 to 380 hp (+45 hp, +13%) and torque from 750 to 850 Nm (+100 Nm). ECU — Bosch VGS3-NAG3. Flashing method: OBD or Bench depending on the unit's protection.
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. AMG E-Performance is a range of hybrid AMG models with an F1-derived electric system. The F1 heritage in AMG hybrid powertrains (Project ONE) comes with a locked electronic architecture. Full-EV Mercedes keep the inverter and BMS locked, so traditional chip tuning does not apply.
The Mercedes community in Europe has a large pool of available Stage files for the standard models. On modern Mercedes, the encryption requires specialised Bench tools. 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 premium segment is a high-output platform with Stage 2 potential. 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.
