The Land Rover Discovery is the ultimate workhorse for Scottish conditions, and ECU remapping ensures it performs at its absolute best. At Bob's Mechanical Repairs near Perth, we remap all modern Discovery variants — from the 2.0 SD4 to the mighty 3.0 SDV6 — delivering genuine improvements in power, torque and fuel economy. The Discovery is built for exactly the kind of driving Scotland demands. Towing on hilly terrain, navigating flooded farm tracks, climbing steep estate roads with a full load — these are daily realities for many Discovery owners in Perthshire and beyond. Yet the factory ECU calibration is a global compromise, leaving significant performance untapped. Our Discovery-specific remaps are calibrated with Scottish terrain in mind. We optimise for loaded driving, hill climbing, and the mix of motorway and rural roads that characterise daily driving in this part of the world. The result is a Discovery that feels more capable, more refined, and more economical — all from a software change that takes 1–2 hours. We regularly remap Discoveries for farming families, estate managers, equestrian enthusiasts and families who need a vehicle that can handle Scotland's weather and terrain while still being comfortable on the school run.

What changes after a Land Rover Discovery remap
Land Rover Discovery owners report:
Transformed towing — The additional torque makes towing feel effortless. Horseboxes, livestock trailers, and boats are handled with ease on Scotland's hilly roads. The Discovery holds speed on gradients that previously required dropping gears.
Off-road authority — The improved low-end torque gives better control on steep, muddy, or rocky terrain. Power delivery is progressive and manageable.
Motorway refinement — The engine operates at lower load at cruise speeds, reducing noise and fuel consumption on long motorway journeys.
Better overtaking — On Perthshire's single carriageway roads, the improved mid-range acceleration makes overtaking safer and more confident.
Land Rover Discovery remapping and fuel economy
Discovery owners covering 15,000+ miles annually stand to save significantly from a fuel-economy remap. Typical improvements of 8–15% translate to £500–900 per year in reduced fuel costs. The heavier Discovery 5 with the 2.0 SD4 engine benefits particularly well, as the standard engine works harder under load.
Is remapping a Land Rover Discovery safe?
Land Rover's diesel engines are engineered for demanding use — the same units power commercial fleet vehicles and are designed to handle continuous heavy loading. Our remaps work within these generous design margins, and every vehicle is comprehensively health-checked before tuning.
Every map is written for the individual vehicle, road-tested before it is handed back, and the original file is kept on record so the car can be returned to standard at any time. Work is carried out at the workshop in Birnam, Dunkeld, Perthshire.
