Qashqai 1.5 DCI SID301 3236303133 SW-3M00044000000 Siemens — ECU Tuning Stage 1  3236303133

This Stage 1 remap transforms the Qashqai’s 1.5 DCI engine into a more responsive and efficient powerplant. Turbo boost maps have been reshaped to eliminate lag and deliver a flatter, stronger torque curve from idle through mid-range, ideal for both urban acceleration and motorway cruising. Injection timing and rail-pressure tables are finely tuned to improve combustion stability, reducing smoke and soot formation while enhancing fuel economy under light load. EGR flow and DPF regeneration parameters are adapted to maintain reliable filter cleaning cycles without impacting driveability or triggering fault codes. The 6-speed manual gearbox shift logic is subtly updated to match the new torque profile, providing crisper, more confident gear changes under load. Throttle-pedal mapping is smoothed to eliminate flat spots during rapid inputs, ensuring an intuitive connection between driver intent and engine response. All calibrations remain strictly within OEM safety margins to safeguard engine and drivetrain longevity. Tested on a professional dynamometer and validated against factory specifications, this ECU tuning delivers a perfect balance of performance gains, fuel-economy benefits, and everyday reliability.

All tuning files were acquired through official EVC.de resellers and verified on a professional dynamometer. Each calibration corresponds to the developer listed in the “Modified By” section — performance graphs may be available on their official website. These files are intended for motorsport or off-road use only. Ensure proper installation and do not operate the vehicle aggressively without first confirming mechanical condition.
