Mercedes S (2002 - W220) 350 (3.7i) 245 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 245 to 250 hp (+5 hp, +2%) and torque from 344 to 349 Nm (+5 Nm). ECU — Bosch ME2.8. Flashing method: OBD or Bench depending on the unit's protection. The 2002 generation — old-era petrol ECUs (ME7/ME9/MED9/Simos) with easily readable memory.
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. On older-generation Mercedes petrol engines, Stage 1 is flashed over OBD without Bench. The Mercedes petrol range spans compacts, premium saloons, SUVs, roadsters and AMG flagships.
Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. The Mercedes community in Europe has a large pool of available Stage files for the standard models. 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.
