Stage 1 mapping targets a quicker boost rise and steadier pull across the mid-range while keeping factory-level refinement. All EGR flow and its diagnostics are disabled, reducing soot buildup and keeping the intake path clean. Torque, boost and smoke limiters are rescaled with balanced air-fuel targets, so the 5-speed gearbox remains within OEM load margins during everyday commuting. Cold-start, idle and light-throttle cells are refined to preserve stock fuel economy on cruise yet deliver a sharper throttle feel in city traffic.
Overview Feature list Copyright info Releases (1) Discussion
- EGR valve flow mapped to zero; related DTCs suppressed
- Torque, boost & smoke limiters lifted for a broader mid-range pull
- Throttle-pedal curve sharpened for quicker tip-in without surge
- Vmax limiter raised for relaxed motorway cruising
- DPF regeneration logic untouched (hardware remains); compatible with stock exhaust
- CVN раtсh applied; flashable via OBD or bench with any EDC17-capable tool
- Cold-start fueling and idle control refined for smoother warm-ups
- Calibration keeps clutch & gearbox protection strategies intact
