Chip tuning for Fiat Punto 1.3 Mjet 95 hp ECU

Fiat Punto (2012) 1.3 Mjet 95 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 95 to 115 hp (+20 hp, +21%) and torque from 200 to 250 Nm (+50 Nm). This engine ships with different ECU variants: 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: 4 configurations · 4 ECU variants. A diesel built in 2012 — the Tricore ECU era; OBD flash works on most production revisions.

The Fiat range covers compacts, saloons, crossovers and commercial models. Mid-generation diesel models use standard OBD read/write.

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. On pre-2017 Fiat models, Stage 1 is done via OBD without bench. On naturally aspirated Fiat engines the main effect is sharper throttle response. Low-output Fiat engines are city units, and Stage 1 is safe on them.
