Chip tuning for Citroen C5 aircross 1.6 THP PureTech GPF Hybrid2 225 hp ECU

Citroen C5 aircross (2018) 1.6 THP PureTech GPF Hybrid2 225 hp — mass-market hybrid engine of the passenger segment of the Stellantis group (Франция, 1919). Stage 1 chip tuning raises power from 225 to 250 hp (+25 hp, +11%) and torque from 360 to 420 Nm (+60 Nm). ECU — Bosch MG1CS042. Flashing method: OBD or Bench depending on the unit's protection.

The Citroen range covers compacts, saloons, SUVs, MPVs and commercial vehicles. Citroen is a French carmaker, founded in 1919 by Andre Citroen. Citroen has a history of innovation, from hydropneumatic suspension to front-wheel drive. Full-EV Citroens keep the inverter and BMS locked. 48V MHEV on the newer Citroens is a mild hybrid. Citroen PHEV variants appear across the crossover and saloon range.

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. High-output Citroens are rare, as the core segment is low and mid.
