Chip tuning for Citroen C4 1.6 HDI 90 hp ECU
Citroen C4 (2005) 1.6 HDI 90 hp — mass-market diesel engine of the passenger segment of the Stellantis group (Франция, 1919). Stage 1 chip tuning raises power from 90 to 115 hp (+25 hp, +28%) and torque from 215 to 260 Nm (+45 Nm). ECU — Bosch EDC16C34. Flashing method: OBD or Bench depending on the unit's protection. The 2005 generation — first-generation CDI/TDI/HDi diesels with relatively simple ECU protection; OBD reading works directly.
Citroen is part of the Stellantis group (formerly PSA Peugeot Citroen). The Citroen range covers compacts, saloons, SUVs, MPVs and commercial vehicles. Citroen is a French carmaker, founded in 1919 by Andre Citroen. The factory calibration on Citroen diesels is conservative, leaving headroom for Stage 1.
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. Low-output Citroen engines are city units, and Stage 1 is safe. On naturally aspirated Citroen engines, the main effect is on throttle response.
