Enhancing every aspect of the 1.7 CRDi’s performance, this Stage 1 calibration refines turbo boost delivery and optimises injection timing to deliver immediate throttle response and robust mid-range torque. Rail pressure maps have been carefully tuned to improve combustion stability and reduce smoke formation, while EGR flow adaptations maintain clean regeneration cycles without sacrificing drivability. Torque and load limiters are safely raised within OEM tolerances to unlock the full 115 PS potential, translating to stronger overtakes and effortless hill climbs. The 6-speed manual gearbox adaptation is synchronised with the increased torque curve, providing crisper shifts and reduced shift shock under load. Throttle mapping has also been smoothed to eliminate flat spots during rapid throttle transitions, ensuring a linear and predictable power delivery. Diagnostic fault routines remain fully operational, safeguarding compatibility with service tools and preserving emission-control functions. Ideal for daily driving and light towing, this calibration strikes the perfect balance between fuel economy improvements and engaging driving dynamics.
