Chip tuning for Renault Kerax 450 DXi11 450hp (331kW) 2140Nm ECU
Renault Kerax (I) 450 DXi11 450hp (331kW) 2140Nm — mass-market diesel engine of the commercial segment of the Renault-Nissan-Mitsubishi Alliance group (Франция, 1899). Stage 1 chip tuning raises power from 450 to 520 hp (+70 hp, +16%) and torque from 2140 to 2460 Nm (+320 Nm).
Renault Sport is the performance division that builds RS models and the Megane Sport. Renault was a pioneer of compact common-rail diesels in Europe. Renault diesel engines are also used in Nissan, Dacia and Mercedes (the Citan/Vito run Renault engines). DPF/SCR with AdBlue is standard on Euro-6 Renault diesels.
On older-generation Renault models, Stage 1 is done via OBD without bench. The Renault community in France and Eastern Europe offers a large pool of ready-made Stage files. Within the Renault-Nissan Alliance, ECUs are partly standardised, so some files carry over between brands. Top-tier Renault Sport engines sit at the power ceiling of the French mass market.
