Chip tuning for Renault Megane 1.5 DCI EU6 (Renault) 90 hp ECU

Renault Megane (2016) 1.5 DCI EU6 (Renault) 90 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 90 to 125 hp (+35 hp, +39%) and torque from 220 to 300 Nm (+80 Nm). This engine ships with different ECU variants: Bosch EDC17C42, Bosch EDC17C84, Siemens/Continental SID310. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 3 configurations · 3 ECU variants. The 2016 generation — mid-generation diesels on the EDC17 platform with OBD reading support and no need for Bench.

Dacia is Renault's mass-market budget sub-brand, built in Romania. Mid-generation diesel models use standard OBD read/write.

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. Low-output Renault engines are city-segment units; Stage 1 is safe. On naturally aspirated Renault engines, the main effect is on throttle response.
