Stage 1 calibration for Land Rover Defender 2.5 TD5 — Software 4195 MEMS3 — crisper throttle, broader torque band, improved off-road tractability.
Stage 1 mapping widens the usable torque plateau on the 2.5 TD5 without sacrificing the engine’s renowned longevity. DPF logic is absent on this platform, but EGR flow and related diagnostics are fully disabled for a cleaner intake charge. Boost, smoke and torque limiters are rescaled with conservative air-fuel targets, keeping driveline stress within OEM margins during low-range work. Cold-start, idle and part-throttle calibrations are refined so cruising economy stays stock while boost builds earlier for smoother pull-away on steep trails.
Overview Feature list Copyright info Releases (1) Discussion
- EGR valve flow mapped to zero; associated DTCs suppressed
- Boost, smoke and torque limiters lifted for stronger mid-range pull
- Throttle-pedal maps sharpened for faster tip-in on technical terrain
- Vmax limiter raised for relaxed highway cruising
- CVN patch applied; flashable via OBD or bench with any MEMS3-capable tool
- Cold-start fueling and idle control refined for quieter warm-ups
- Calibration maintains OEM driveline safety margins for sustained low-range use
