The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. The 2016 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.
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. Mercedes-Benz is the world's oldest carmaker, founded in 1926 by the merger of Daimler-Motoren-Gesellschaft and Benz & Cie. Brabus is an independent Mercedes tuning house specialising in top-model upgrades. The factory calibration on Mercedes petrol engines is conservative, leaving headroom for Stage 1. Mid-generation petrol models use standard OBD flash.
On Mercedes up to the recent generation, Stage 1 OBD flash is available. AMG engines confidently reach Stage 2 with a downpipe + intake. Mercedes is one of the most protected brands in the chip tuning industry in terms of encryption. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects. Bench reading is a mandatory procedure for modern AMG models. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant.
