Chip tuning for Fiat Grande Punto 1.3 Mjet 75 hp ECU
Fiat Grande Punto (2005) 1.3 Mjet 75 hp — mass-market diesel engine of the passenger segment of the Stellantis (бывш. FCA — Fiat Chrysler Automobiles) group (Италия, 1899). Stage 1 chip tuning raises power from 75 to 95 hp (+20 hp, +27%) and torque from 190 to 240 Nm (+50 Nm). This engine ships with different ECU variants: Marelli MJD6, Marelli MJD8, Marelli MJD8DMF, Marelli MJD8F2, Marelli MJD8F3. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 5 configurations · 5 ECU variants. The 2005 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.
Fiat is one of the founders of Stellantis, formed by the merger of FCA and PSA in 2021. Fiat-Iveco engines are widely used in the Stellantis commercial segment.
The Fiat community in Italy offers a large pool of ready-made Stage files for compacts and the Ducato. Within Stellantis, ECUs are standardised across platforms, so some files work on Fiat/Citroen/Peugeot. Low-output Fiat engines are city units, and Stage 1 is safe on them. On naturally aspirated Fiat engines the main effect is sharper throttle response.
