Chip tuning for Renault Modus 1.5 DCI EU4 65 hp ECU

Renault Modus (2004) 1.5 DCI EU4 65 hp — mass-market diesel engine of the passenger segment of the Renault-Nissan-Mitsubishi Alliance group (Франция, 1899). Stage 1 chip tuning raises power from 65 to 90 hp (+25 hp, +38%) and torque from 160 to 200 Nm (+40 Nm). Diesel engines built in 2004 — the era of classic Common Rail without strong encryption.

The Renault range covers compacts, saloons, SUVs, MPVs and commercial vehicles. Renault was a pioneer of compact common-rail diesels in Europe.

Within the Renault-Nissan Alliance, ECUs are partly standardised, so some files carry over between brands. The Renault community in France and Eastern Europe offers a large pool of ready-made Stage files. On naturally aspirated Renault engines, the main effect is on throttle response. Low-output Renault engines are city-segment units; Stage 1 is safe.
