Mercedes CLA (2016 - C117-X117) 250 EU6 (2.0T) sport 218 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 218 to 245 hp (+27 hp, +12%) and torque from 350 to 400 Nm (+50 Nm). This engine ships with different ECU variants: Bosch MED17.2.2, Bosch MED17.7.2, Bosch VGS2-FDCT gen1, Bosch VGS2-FDCT gen2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 4 configurations · 4 ECU variants. The 2016 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.
The Mercedes-Benz Group AG (Daimler AG until 2022) comprises Mercedes-Benz, AMG, Maybach, Smart and the EQ line. AMG is the performance division of Mercedes (since 1967), building engines on the 'one man, one engine' principle in Affalterbach. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships. Mercedes encryption is among the toughest in the industry, especially on modern models. Maybach uses Mercedes engines for the ultra-luxury segment, with the emphasis on quietness and smoothness.
The Mercedes community in Europe has a large pool of available Stage files for the standard models. On Mercedes up to the recent generation, Stage 1 OBD flash is available. 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.
