Stage 2 AI Performance Chip Module OBD2 for Citroen – Adaptive Power & Fuel Efficiency

Avant-Garde Performance for Your Citroën

Citroën vehicles are celebrated for their distinctive "Creative Technologie" and the legendary Citroën Advanced Comfort® program. Whether you drive a nimble C3, a versatile Berlingo, or the flagship C5 X, your car is designed to be a sanctuary of smooth driving. However, to comply with strict Euro emissions standards and tax brackets, factory ECU tuning often restricts the engine's true capabilities, resulting in throttle hesitation and a lack of low-end punch.

The Stage 2 SMARTTUNE with AI Technology is the intelligent upgrade tailored for the chevron brand. This is not a crude tuning box; it is a sophisticated, AI-driven OBD2 module that interfaces with your Citroën’s BSI (Built-in Systems Interface) and engine management. It learns your driving style—whether you are navigating urban streets or cruising the autoroute—to unlock the responsive, effortless power that complements your vehicle's comfort.

Optimized for PureTech and BlueHDi Engines

Citroën’s modern powertrain lineup, including the award-winning PureTech petrol and efficient BlueHDi diesel engines, is engineering brilliance restricted by software. Our AI technology safely optimizes boost pressure, fuel rail pressure, and ignition timing to release that hidden potential.

• Revitalize PureTech Turbos: The 1.2L PureTech engine is punchy but can suffer from turbo lag at low RPMs. We optimize the signal to provide up to 50% better throttle response, making city driving smoother and highway merging safer.
• BlueHDi Torque Boost: For Berlingo, SpaceTourer, and C5 Aircross diesel owners, torque is essential. Gain up to 28.6 ft·lbs of added torque, which significantly helps when the vehicle is fully loaded with passengers or cargo.
• EAT8 Transmission Synergy: Designed to work in perfect harmony with the EAT6 and EAT8 automatic gearboxes. The chip ensures that the increased power doesn't result in jerky shifts, maintaining the "magic carpet" smoothness Citroën is famous for.
• Eco-Driving Efficiency: By refining the combustion cycle, the module allows you to maintain cruising speeds with less throttle input, potentially improving fuel economy by up to 2 MPG—perfect for long-distance touring.

Frequently Asked Questions

Will this work on the C4 Picasso/SpaceTourer?
Yes. These MPVs often feel heavy when fully loaded. The Stage 2 SMARTTUNE provides the extra torque needed to make hauling the family feel effortless, reducing the need to downshift on hills.

Does it work with the "Stop & Start" system?
Yes. The chip detects when the engine is running and optimizes performance accordingly. It does not interfere with the operation of Citroën’s Stop & Start technology.

Is it safe for the THP engines (known for timing chain sensitivity)?
Yes. The chip optimizes performance within safe parameters. It does not push the engine beyond its mechanical limits, ensuring that common mechanical sensitivities are not exacerbated.

Will it affect my suspension settings (Hydraulic or Progressive Cushions)?
No. The chip focuses solely on engine management. Your suspension comfort remains exactly as Citroën intended—just with more power to pull you along.
