Chip tuning for Mercedes Arocs OM936 SCR 7.7 (EU6) 354hp (260kW) 1400Nm ECU
Mercedes Arocs (I (2013+)) OM936 SCR 7.7 (EU6) 354hp (260kW) 1400Nm — premium diesel engine of the commercial segment of the Mercedes-Benz Group AG (Mercedes-Benz, AMG, Maybach, Smart, EQ) group (Германия, 1926). Stage 1 chip tuning raises power from 354 to 404 hp (+50 hp, +14%) and torque from 1400 to 1695 Nm (+295 Nm). A diesel built in 2013 — the Tricore ECU era; OBD flash works on most production revisions.
4MATIC all-wheel drive is Mercedes' signature system, fitted to most models. 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. The factory calibration on Mercedes diesels is conservative, leaving headroom for Stage 1 while preserving engine life. DPF/SCR with AdBlue is standard on all Euro-6 Mercedes diesels. Mid-generation diesel models use standard OBD read/write.
Stage 1 on Mercedes often requires refreshing the adaptations after the flash. Top AMG engines sit at the Mercedes power ceiling, and the gain is significant. AMG engines are a well-known base once hardware is added (downpipe + intake + intercooler). Brabus is a premium alternative to AMG for the top models. AMG Performance Studio is Mercedes's in-house tuning studio for bespoke projects.
