Chip tuning for Mercedes GL 450 (4.7i) 340 hp ECU
Mercedes GL (2012 - X166) 450 (4.7i) 340 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 340 to 360 hp (+20 hp, +6%) and torque from 460 to 490 Nm (+30 Nm). ECU — Bosch ME9.7. Flashing method: OBD or Bench depending on the unit's protection. In the CHIPOK database: 2 configurations. The 2012 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. High-output Mercedes turbo petrol engines are the flagship models, and Stage 1 delivers a solid gain. Mid-generation petrol models use standard OBD flash. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships.
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. 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.
