Fiat's MultiJet diesel and TwinAir/T-Jet turbocharged petrol engines offer excellent tuning potential within their compact displacement. The 1.3 MultiJet, 1.6 MultiJet and 1.4 T-Jet are all proven platforms with well-documented tuning results.
The Fiat Tipo and 500X with the 1.6 MultiJet diesel respond to Stage 1 with +30–45 Nm and +20–30 hp. The 1.4 T-Jet petrol engine, found in the 500 and Grande Punto Abarth, delivers similar gains. The MultiJet II diesel family is among the best diesel tuning platforms in the compact segment.
Fiat ECU tuning is performed via OBD port on all modern MultiJet and TJet applications. Older vehicles may require bench tuning. All maps are fully reversible. Fiat tuning offers outstanding value for owners on a budget.
