Factory van maps are written for an empty vehicle on a test cycle. Yours lives loaded, on a schedule, up the same hills every day. Van remapping fills in the low-rev torque your tools and tow bar need — typically 6–12% better MPG on high-mileage routes, plus a van that actually pulls when it's full.
A loaded van is a different machine to the empty one the factory tuned.
Every work van shares the same factory compromise: calibration written for an unladen vehicle on an emissions cycle, then sold to someone who loads it to the axles, does short urban drops and motorway miles in the same week. The result is an engine that labours in low gears, burns fuel in unnecessary downshifts, and frustrates the driver on every slip road and hill start.
Van remapping fixes the mismatch with a custom file written for your exact engine — Transit EcoBlue, Sprinter OM654, Crafter TDI, Vivaro diesel and more. Low-rev torque filled in hard so loaded pulls happen a gear higher. Throttle mapping smoothed so different driving styles waste less fuel. Injection refined at the cruise sites where your routes actually live. DPF, EGR and AdBlue stay fully intact — this is efficiency engineering, not emissions deletion.
We diagnose every van before flashing: soot loading, boost health, sensor plausibility. Warning lights and limp modes get sorted first — tuning over a fault just accelerates the bill. Mobile visits to your yard, driveway or workplace across Lancashire and Greater Manchester; original file archived for life; written spec sheet for insurance and fleet records. Running two or more vans? See fleet tuning for volume rates and a pilot programme.
Send your registration to confirm compatibility and expected gains for your exact engine code — not every variant tunes the same.
Six workstreams in every van file — tap each one for the plain-English version.
Low-rev torque raised substantially so a loaded van stops needing two downshifts for every gradient.
The change drivers feel first: useful pull from 1,400 rpm instead of 2,200. Hill starts with tools in the back, slip-road merges with a trailer on — a gear higher and a lot calmer.
Injection timing and pressure refined at steady-state load sites where work vans spend their hours.
Courier and trades mileage is mostly cruise. Cleaner combustion at 56–70 mph load sites means measurable fuel savings compounded across every motorway hour you run.
Pedal mapping that holds speed with smaller, steadier inputs — the over-fuelling twitch removed.
Van throttles are often mapped aggressively for an empty vehicle. We smooth the response so urban drops and motorway cruising both use less fuel for the same job.
Combustion kept clean and EGTs healthy — kinder to the regeneration cycle on stop-start duty.
A torquier calibration driven at lower revs produces less soot per mile. Everything stays fitted and MOT-compliant — vans already blocked need assessment first.
Mid-range torque shaped for towing boxes, plant trailers and loaded runs — mention your use when booking.
Builders and landscapers towing daily benefit from the same low-rev fill as motorway couriers — we bias the file to how you actually use the van. See our remap for towing guide.
DPF, EGR, AdBlue and every factory safeguard stay exactly as designed.
Van remapping refines combustion efficiency — it does not remove emissions hardware. MOT, roadside compliance and O-licence obligations are unaffected. Clean tuning, no asterisks.
Your mileage, your MPG, your fuel price — see what 6–12% is worth per year on a working van.

Diagnostics first, backup, custom file, verify — usually 1–2 hours and the van's back earning.
Three things we say before taking your money — because vans need to keep working.
Remapping a lease or contract-hire van without the funder's written approval creates problems at hand-back — and some funders simply say no.
We ask about ownership up front. Owned vans are straightforward; leased ones need a yes in writing. Full reversion before lease return is a routine visit — your original file is archived for exactly that reason.
The urban multi-drop van and the motorway tramper bank different percentages from the same calibration. Anyone promising a single figure for every route is guessing.
We quote the honest 6–12% range for healthy turbo-diesels on real miles, explain where your use case likely sits, and let the calculator above do the sums. Under-promised, over-delivered.
High-mileage work vans carry lazy turbos, sooted EGRs and tired DPFs. Software cannot fix hardware — and adding torque over a fault makes it worse.
Every van is scanned before we flash. If it's not a good candidate we say so and quote diagnostics or repair first. Protecting your livelihood beats a quick sale.
Send your reg and tell us how the van earns its keep — we'll recommend the right file and quote the exact price.
From £150 per van depending on engine, ECU type and calibration complexity. Ford Transit EcoBlue, Mercedes Sprinter and VW Crafter platforms typically sit at the £150 end; some older or specialist ECUs may quote higher after we check your registration. Mobile visits within our coverage zone carry no call-out fee — the quote we give is the price you pay.
Yes — Transit, Transit Custom, Transit Connect EcoBlue, Mercedes Sprinter, VW Crafter, Vauxhall Vivaro, Renault Master and Peugeot/Citroën Boxer/Dispatch are among our most common van bookings. Each engine variant gets its own custom file — send your reg and we confirm compatibility and realistic torque and MPG expectations.
That's the main point. Factory maps are biased toward unladen running; we fill in low-rev torque so loaded hill starts, slip-road merges and towing pulls happen with less downshifting and less right-foot drama. Drivers consistently report the van feels lighter even when it isn't — because the engine is working less hard for the same job.
Same £150 starting point and same core efficiency engineering, but a van file is biased toward loaded drivability, towing and high-mileage commercial use. The economy remap page covers cars and vans where pure MPG is the only goal. Tell us how you use the van and we'll recommend the right bias — or Stage 1 if you want more outright performance.
Emissions hardware stays intact so MOT testing is unaffected. Insurance: any ECU modification should be declared — we provide a written spec sheet that makes the call straightforward. Lease: get written permission from the funder before booking; we won't tune around a no. Owned vans are simple — declare to insurer, keep our documentation, revert to stock any time from your archived original file.
Usually yes once you're at two or more vehicles. Fleet tuning offers volume rates, on-site yard visits scheduled around your rota, a pilot van to prove savings on your own routes, and per-vehicle documentation. One van? This page is the right place — same calibration quality, single-van pricing.
Volume rates, pilot vehicle first, on-site yard visits and per-van records across the whole fleet.
