Citroen C1 (2018) 1.0 Vti 72 hp — mass-market petrol engine of the passenger segment of the Stellantis group (Франция, 1919). Stage 1 chip tuning raises power from 72 to 79 hp (+7 hp, +10%) and torque from 95 to 102 Nm (+7 Nm). This engine ships with different ECU variants: Bosch ME17.9.53, Siemens/Continental V56.12. The flashing method is determined by the specific unit: OBD, Bench or Boot mode. In the CHIPOK database: 2 configurations · 2 ECU variants. A 2018 petrol engine — the latest era of encrypted firmware; OBD access is available on production units, Bench on sport models.
Citroen has a history of innovation, from hydropneumatic suspension to front-wheel drive. Citroen shares platforms and engines with Peugeot, Opel/Vauxhall and DS within Stellantis. Citroen is part of the Stellantis group (formerly PSA Peugeot Citroen). Modern Citroen petrol engines use Tricore ECUs, often requiring Bench. Low-output Citroen petrol engines are naturally aspirated city units, so the gain is modest. The Citroen petrol range is shared with Peugeot and Opel within Stellantis.
The Citroen community in France and Western Europe has a large pool of Stage files. ECUs are standardised across Stellantis, so Citroen files often work on Peugeot/Opel/DS. Modern Citroens use Tricore TPROT protection, so a Bench read is required. On naturally aspirated Citroen engines, the main effect is on throttle response. Low-output Citroen engines are city units, and Stage 1 is safe.
