Qashqai 1.5 DCI SID301 1113M00060000000 SW-BR32A Siemens — ECU Tuning Stage 1  - Product specifications

This Stage 1 remap breathes new life into the Qashqai’s 1.5 DCI engine by reworking turbo boost and injection timing for a flatter, more potent torque curve. Boost delivery is sharpened to eliminate lag, while rail-pressure and fuel-quantity maps are finely tuned to improve combustion stability and reduce soot formation. Adaptive EGR flow and DPF regeneration parameters ensure reliable filter cleaning without impacting driveability or triggering fault codes. The 6-speed manual gearbox shift logic is updated to match the enhanced torque profile, providing crisper, more confident gear changes under load. Throttle-pedal mapping is smoothed to eliminate flat spots during rapid inputs, delivering an intuitive, linear power delivery. All adjustments remain strictly within OEM safety margins, balancing significant performance gains with fuel-economy benefits and everyday reliability.
