Campervan & Motorhome Tunes
Tuned for the weight you actually carry.
Most factory motorhome chassis are derated for a homologation test cycle, not for a 3.5-tonne touring rig with bikes on the back. Our campervan recipe is calibrated at GVW — fully laden, full water, full habitation — so the gains are real on the road, not just on the dyno.
Hill-climb torque
Peak torque shifted lower in the rev range so you stop downshifting on every gradient.
Cruise MPG
Leaner cruise fuelling and earlier upshifts in autoboxes — typical 2-4mpg gain at motorway speed.
Towing-ready
Pair with a towing recipe if you tow a small trailer or motorbike behind the van.
Why does a motorhome need a different tune to a van?
A panel van leaves the factory with software calibrated for an empty load floor. Your motorhome carries 3-4 tonnes of habitation, water, leisure batteries, awnings, bikes, and people. Stock fuelling and boost maps are conservative because the factory has no idea what you've loaded. We map for fully-laden touring — stronger torque where you actually need it, on hills, in second gear, towing a trailer.
Will it harm my engine?
Every map runs through 55 safety checks before it touches your ECU — torque limits, EGT margins, rail pressure, smoke models, thermal headroom. We tune within the factory's mechanical envelope, not above it. The same engine block sells in higher-output factory variants — we calibrate to those headroom limits, not past them.
Will it affect my warranty or insurance?
Manufacturer warranty: any modification can affect warranty claims for related components. Most owners outside warranty don't worry. Insurance: we'll provide written documentation of the changes so you can declare it. Most specialist motorhome insurers (e.g. Caravan Guard, Comfort, Safeguard) accept declared remaps without a premium increase. We'll never lie about it.
Can you do this on a Fiat Ducato 2.3 / 3.0 Multijet?
Yes. Ducato (Bosch EDC16, EDC17, MED17, Continental SID variants) is our most-tuned chassis. We have proven recipes for every Multijet variant 2006 onwards plus the newer X290 / X295 platforms. Boxer and Relay (same platform) too.
Sprinter, Crafter, Transit, Master?
Sprinter (Bosch CRD3, EDC17): full coverage. Crafter (EDC17, MED17): yes. Transit Custom & full-size Transit (Delphi DCM, Continental SID): yes. Master, Movano (Bosch EDC17, Delphi DCM): yes. If your reg is on a different chassis, send it through and we'll confirm before you book.
Towing Tunes
Pull harder. Change up sooner. Save fuel.
Every towing tune is dyno-validated under simulated load, with EGT and rail-pressure margins held within factory limits. We never push torque limiters past the gearbox or driveline rating — the goal is real-world capability, not bragging-rights numbers.
Caravans
Stronger low-end torque for hill starts, motorway pulls, and fully-loaded touring weights.
Horseboxes
Calibrated at trailered weight — 2.5-3.5t — for smoother power delivery, kinder to the horses.
Plant + transporters
Heavy single-axle trailers, car transporters, mini diggers. Recipes for Ranger, Hilux, L200, Amarok, Defender, Discovery.
What does a towing tune actually change?
We move the torque curve down the rev range. Stock factory maps push peak torque to 2,000-2,500rpm to chase MPG figures on the test cycle. With a tow load, you spend most of your time below that — climbing in third gear, pulling away from junctions with 1.5 tonnes behind you. We push usable torque down to 1,400-1,800rpm where towing actually happens. Same peak figures, completely different driving experience under load.
Will my insurance cover it?
Declared remaps are accepted by most mainstream insurers and every specialist towing/caravan insurer. We provide written documentation of every change so the declaration is straightforward. Failing to declare is the only thing that voids cover.
Will it pass MOT?
Yes. A remap doesn't affect any MOT test parameter — emissions are tested at idle and 2,500rpm, well within stock fuelling. We don't touch DPF, EGR, or AdBlue on road-going cars. Anything that would fail an MOT we won't do.
I tow a 3.5t triple-axle horsebox — is my Sprinter 313 enough?
Yes for moving the load. The factory rates the engine for 3.5t braked at 2,800kg train weight. Where stock falls short is the experience — rev-bouncing on motorway hills, downshifting too early, drinking fuel in third. A towing tune fixes all three without exceeding any mechanical limit.
Plant trailers and car transporters?
Same platform as horseboxes. Land Rover Defender / Discovery, Ford Ranger, VW Amarok, Mitsubishi L200, Toyota Hilux, Isuzu D-Max — all fully supported with proven towing recipes.
