Chip tuning for Fiat Fullback 2.4 D 181 hp ECU

Fiat Fullback (2016) 2.4 D 181 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 181 to 225 hp (+44 hp, +24%) and torque from 430 to 510 Nm (+80 Nm). A diesel built in 2016 — the Tricore ECU era; OBD flash works on most production revisions.

Fiat is an Italian carmaker from Turin, founded in 1899. DPF/SCR with AdBlue is standard on all Euro-6 Fiat diesels.

On Fiat diesels, Stage 1 delivers a noticeable torque gain. On pre-2017 Fiat models, Stage 1 is done via OBD without bench. 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.
