About remapping
The Land Rover Defender accounts for 250 files in our catalogue, with the 2.5 TD5 five-cylinder of the classic era and the 2.2 and 2.4 TDCi of the later Ford-engined cars. It is one of the most recognisable off-roaders ever built, with an exceptionally loyal following.
Stage 1 makes up 224 files, with 40 EGR off and 12 speed limiter removals. The ECUs include Siemens SID208, Ford DCU102 and DCU106, plus the MEMS3 unit on the classic TD5 models.

What is the TD5?
It is the five-cylinder diesel of the classic Defender era, with its own MEMS3 management. It has a strong following and is well covered in our catalogue.
Does it affect off-road use?
A well-judged map preserves throttle progressiveness, which is essential in technical driving. The file should aim for usable delivery, not peak figures.
Do you cover the later TDCi engines?
Yes, the 2.2 and 2.4 TDCi of the Ford-engined cars are present alongside the classic TD5.
