Dacia is a Romanian carmaker, founded in 1966 and owned by Renault since 1999. Dacia uses Renault engines and platforms. Dacia positions itself as an affordable alternative to Renault — the same quality at a lower price. Dacia uses Renault's dCi diesel engines. Dacia diesels are a mainstream chip tuning subject across Eastern Europe and the CIS. On older Dacia dCi engines, Stage 1 is a straightforward OBD job.
The Dacia community in Eastern Europe and the CIS enjoys a large library of ready-made Stage files. Within the Renault-Nissan Alliance, ECUs are standardised, so Dacia files often work on Renault. Low-output Dacia engines are city-segment units; Stage 1 is safe.
