Chip tuning for Fiat Cronos 1.8i flexfuel 139 hp ECU
Fiat Cronos (2018) 1.8i flexfuel 139 hp — mass-market petrol engine of the passenger segment of the Stellantis (бывш. FCA — Fiat Chrysler Automobiles) group (Италия, 1899). Stage 1 chip tuning raises power from 139 to 150 hp (+11 hp, +8%) and torque from 190 to 210 Nm (+20 Nm). ECU — Marelli 10GF. Flashing method: OBD or Bench depending on the unit's protection. A 2018 petrol engine — the latest era of encrypted firmware; OBD access is available on production units, Bench on sport models.
Fiat has historically specialised in compact and city cars. On mid-range Fiat turbo petrol engines, Stage 1 delivers a noticeable gain. TwinAir is Fiat's signature designation for its two-cylinder turbo engines in the micro segment. Fiat shares some ECUs and algorithms with Alfa Romeo and Lancia.
On mid-range Fiat petrol engines, Stage 1 delivers a noticeable gain. Protection on modern Fiat models uses Tricore TPROT, so Bench is required. Within Stellantis, ECUs are standardised across platforms, so some files work on Fiat/Citroen/Peugeot. The Fiat community in Southern Europe has a large pool of ready-made Stage files. Mid-range Fiat engines are a high-volume chip tuning subject.
