Land Rover Defender D250 Stage 1 Remap
On Land Rover Defender D250 diesel engines a Stage 1 remap recalibrates the fuel quantity, injection timing, boost pressure and torque limiter maps. No hardware is changed and the original software is backed up. The same engine is sold with different stock outputs across generations, so the gain depends on your version.
It depends on the generation and the stock output. D250 engines with 249–250 bhp reach 311–312 bhp with a Stage 1 remap; the largest gain is +62 bhp (L663 D250 249hp). Pick your version in the table below.

GP Power ECU applies the software at its workshop in Hukou, Hsinchu, using EcuPrime-developed files; workshops can also order the file directly.
About the Jaguar Land Rover Ingenium 2.0 diesel (D150, D165, D180, D200, D240)
The Ingenium 2.0 diesel powers the post-2015 Range Rover Evoque, Velar, Discovery Sport, Defender, Jaguar XE, XF, F-Pace and E-Pace, in single and twin-turbo forms from 150 to 240 hp, with AdBlue and a DPF.
How a Stage 1 remap works on the Land Rover Defender D250
Stage 1 recalibrates rail pressure, injection, boost and the torque limiter. Since the 150 and 180 hp outputs share hardware, the gain is clear. The 9-speed automatic's capacity and the all-wheel-drive system are respected.
Pre-remap checklist
- Oil dilution and DPF regeneration history (a known issue on this engine).
- Timing chain noise on early production.
- AdBlue system and NOx sensors.
- EGR cooler and boost leaks.
