Stage 1 Dacia Logan 1.5 DCI — Bosch EDC17_C42 Firmware 536444 - Releases

This comprehensive tuning package takes your Dacia Logan 1.5 DCI beyond factory settings, delivering a balanced performance uplift tailored for both daily driving and spirited acceleration. By carefully remapping turbo boost pressure at low and mid-RPMs, turbo lag is minimized and surge is more linear, resulting in faster response the moment you floor the throttle. Fuel injection quantity and timing tables are optimized to improve combustion efficiency, yielding a clearer power delivery curve and reducing abrupt transitions between load zones. Torque and smoke limiters have been raised to unlock additional pulling power, while maintaining safe engine temperatures and emissions compliance under normal conditions. Adaptations for the 5-speed manual gearbox ensure smoother shifts under higher load, reducing gear shock and enhancing longevity of transmission components. Secondary systems like EGR and DPF regeneration thresholds are recalibrated to limit soot buildup and extend filter intervals, without disabling emissions controls entirely. Overall, this Stage 1 map offers stronger mid-range punch, improved off-the-line acceleration, and a refined throttle feel—perfect for drivers seeking a reliable yet spirited upgrade.
