This engine ships with different ECU variants: Delphi CPC2, Bosch MED17.7.2, Bosch VGS2-FDCT gen1, Bosch VGS2-FDCT gen2, Siemens/Continental VGS4-NAG2, Siemens/Continental VGSx-NAG2. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 12 configurations · 6 ECU variants. A 2019 petrol engine — the latest era of encrypted firmware; OBD access is available on production units, Bench on sport models.
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. Maybach is Mercedes's ultra-luxury sub-brand. High-output Mercedes turbo petrol engines are the flagship models, and Stage 1 delivers a solid gain. Mercedes encryption is among the toughest in the industry, especially on modern models. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1.
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. Stage 1 on Mercedes often requires refreshing the adaptations after the flash. 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. High-output Mercedes engines are premium-class with solid headroom for Stage 1.
