Carrying a load
Discuss the response you want when carrying tools, equipment or a full motorhome payload.
At our Llandow workshop
Remapping for the way you use your van
Whether it carries tools every day, tows a trailer or takes the family away, your vehicle deserves a calibration suited to its engine and its job.
We discuss your van or motorhome, check its ECU and condition, and agree the work before writing the calibration.
Stage 1 remappingFrom £250Normally £400. Some ECUs cost more; we confirm the price for your vehicle.
Built around real journeys
Tell us how you use the vehicle so we can discuss a suitable approach. The result depends on the engine, vehicle condition and calibration.
Towing
Tell us what you tow and how often, so the intended use forms part of the conversation.
Hills and longer trips
We can discuss how the vehicle responds on gradients and during longer journeys.
Everyday drivability
Talk to us about throttle response and the way you drive, not just a peak power figure.
Results vary. We cannot promise a particular power increase, towing improvement or fuel saving. Driving style, load, terrain and the vehicle's condition all matter.
What would you like to improve?
Every van and motorhome is used differently. These illustrative examples show the sort of conversation we can have about your vehicle; they are not customer testimonials or guaranteed results.
"My motorhome struggles on hills"
A fully loaded motorhome can feel short of pulling power on gradients. Tell us where it struggles and whether you tow. We can check its condition and discuss a calibration suited to its engine and load.
"I want to improve fuel economy"
Some customers tell us they have seen around 5 mpg better after remapping, including owners of large motorhomes. This is customer feedback, not a guaranteed or independently measured result. Consumption also depends on speed, load, terrain and vehicle condition.
"My van spends all day in traffic"
Stop-start deliveries and busy commutes call for predictable response at everyday speeds. Tell us how the van feels in traffic so we can discuss your priorities and check whether the vehicle is suitable.
"I regularly carry tools or tow"
A van working near its usual load or pulling a trailer may need a different approach from an empty vehicle. We will discuss your typical use, engine condition and the limits of the vehicle before agreeing work.
"I tow a caravan on holiday"
Pulling a caravan adds load, particularly on hills and longer journeys. Tell us what you tow and how the vehicle responds so we can discuss a suitable approach for its engine and condition.
"My van is always fully loaded"
Tools, materials and equipment add weight to a working van. We can discuss its everyday response under load and check its suitability before agreeing any remapping work.
Start with a healthy vehicle. If power has dropped, a warning light is on or the engine is running poorly, diagnosis may be needed first. Results vary and safe loading and towing limits still apply.
Vans, campers and motorhomes
Tell us what you drive
We work with Transit Customs, other Transits, Volkswagen Transporters and Crafters, panel vans, camper conversions and coachbuilt motorhomes.
Motorhomes are also built on bases such as Fiat Ducato, Peugeot Boxer, Citroën Relay and Mercedes-Benz Sprinter. Send the registration and engine details so we can check the specific ECU and whether your vehicle is supported.
For fleets, send the registrations together. Each vehicle is checked and quoted for its own ECU.

Other makes and conversions
Have a different motorhome or camper conversion? Send us the registration and details so we can check it.

Carbon build-up in vans and motorhomes
Cleaning suited to your vehicle
Over time, carbon deposits can build up in engines and intake systems. Short trips, long periods of storage and the way a vehicle is used can all be relevant when assessing its condition. If your motorhome or van feels different or has a warning light, tell us about the symptoms so we can identify what needs attention.
We offer carbon cleaning options for nearly all motorhomes. The right method depends on the engine, where the deposits are and how accessible they are. We will check your vehicle and discuss suitability before recommending a treatment; cleaning does not replace diagnosis or repair.
From enquiry to calibration
We agree the scope for your particular vehicle before work starts.
- Tell us about the vehicleSend the registration, mileage, vehicle type, typical load and any towing or modifications.
- Confirm suitability and priceWe check the engine and ECU, discuss your requirements and confirm the proposed quote.
- Check its conditionTell us about warning lights or running faults. We agree any further checks or diagnosis needed before remapping.
- Carry out the agreed workWe write and check the calibration at the workshop and explain the outcome and any findings.
Pricing and vehicle checks
Stage 1From £250
Normally £400. Some ECUs cost more. Stage 1 is for a healthy standard vehicle and does not require hardware changes.
We confirm the actual price for your registration and ECU before booking.
Fit to Map checkFrom £95
A DPF regeneration problem, AdBlue warning, boost leak or slipping clutch should be identified before a file is written.
We’ll confirm whether a Fit to Map check or further diagnosis is needed and how it will be charged when we quote.
At the workshop beside Llandow circuit
We write and check files at our workshop. Cell one uses the Dyno Developments rolling road; a four-wheel-drive van uses the MAHA cell.
Motorhomes and taller vans vary considerably. Send the vehicle's height, length, weight and any photographs before travelling so we can confirm access, dyno suitability and booking arrangements. Do not assume every vehicle will fit.

Questions before booking
Find out what to expect before bringing your van or motorhome to us.
Will my van or motorhome fit on the dyno?
That depends on its dimensions, weight, drivetrain and configuration. Send us the details and we will confirm suitability before the appointment.
How long will the appointment take?
Timing varies with the ECU, vehicle access and any checks required. We will confirm arrangements when we quote.
What if there is a warning light or an existing fault?
Let us know before booking. We may recommend diagnosis or repairs first; the scope and cost of any additional work will be agreed with you.
Will a remap affect my warranty or insurance?
Terms differ between providers. Tell your insurer about modifications and check your warranty or finance terms before proceeding. Read our tuning risks and warranty information.
Can remapping guarantee better fuel economy?
No. Some customers report around 5 mpg better after remapping, including in large motorhomes, but individual results vary and this feedback is not an independently measured result. Driving style, journeys, load and vehicle condition all affect consumption, so we cannot guarantee a saving.
Tell us about your van or motorhome
Send your registration, mileage, vehicle type, typical load, towing use, modifications and any warning lights or symptoms. For a motorhome or larger van, include its dimensions and weight.
We’ll check the ECU, discuss suitability and confirm the next step and price.
