HGV & Truck ECU Remapping
Cut fuel costs, improve drivability and keep your fleet moving. We provide economy and performance remapping for trucks, HGVs and vans — plus AdBlue and DPF solutions for off-road, agricultural and export vehicles.
Legal Notice — Off-Road & Non-Road Use Only
Under UK law, removing, disabling or tampering with emissions control systems (including AdBlue, SCR (Selective Catalytic Reduction), and DPF (Diesel Particulate Filter)) on a vehicle used on public roads is illegal. This may breach the Road Vehicles (Construction and Use) Regulations 1986, cause MOT failure, attract DVSA enforcement and fines, invalidate your insurance, and lead to prosecution.
We only offer these services where the vehicle is used exclusively off-road, on private land, as agricultural or plant machinery, for motorsport, for export outside the UK, or in other lawful non-road applications. By requesting this service you confirm the vehicle will not be driven on UK public roads with emissions systems modified.
ECU Tuner UK does not encourage or assist illegal use of modified vehicles on public highways.

FAQs
Do you tune HGVs, trucks and vans?
Yes. We work on light commercials, trucks, HGVs and agricultural/plant machinery from most major manufacturers.
How much fuel can a remap save on a fleet?
Savings depend on engine, route profile and driver behaviour. Economy tuning typically targets meaningful per-vehicle savings that scale across a fleet — we confirm realistic expectations after reviewing your vehicles.
Can you come to our depot?
Yes. We offer a mobile service across Southampton, the New Forest and surrounding areas to minimise downtime.
Is this legal for road use in the UK?
No. Removing or disabling DPF, EGR, AdBlue or SCR emissions systems is illegal for vehicles used on UK public roads. It can cause MOT failure, DVSA penalties, invalidated insurance, and prosecution under the Road Vehicles (Construction and Use) Regulations 1986. We only provide these services for off-road, agricultural/plant, motorsport, export, or other lawful non-road use. You must confirm your vehicle will not be used on public highways with modified emissions systems.
