What this service is
What it is
Mobile remapping is exactly the same workshop-grade service, delivered at your location. The diagnostic equipment, programming interfaces, laptop, power stabiliser and file library all travel in the van, so nothing about the quality of the job changes because of where it happens.
Who it's for
Anyone who cannot afford to lose a working day: commuters, shift workers, tradespeople, fleet managers, farmers, parents with school runs, and anyone whose vehicle is booked solid Monday to Friday.
When you need it
Whenever suits you. Mon–Sat, 9am–8pm, including early mornings before work and evening slots after it. Booking is usually same-week across most of South Wales.
Why professional matters
Because a remap does not require a ramp, a dyno or a workshop bay. It requires a stable power supply, the right interface, an experienced calibrator and somewhere safe to road test — all of which we bring to you.
What it costs to ignore it
The traditional model asks you to hand over your vehicle for a day and hope. There is no reason for that any more.
Our process
Every mobile remapping job follows the same disciplined sequence — so the result is predictable, repeatable and guaranteed.
Send your reg and what you want from the vehicle. You get an honest, fixed price and a realistic expectation of the gains — no obligation.
Home, work, yard or farm. Mon–Sat 9am–8pm, including early and late slots so you keep your working day.
Full fault-code read, live data and a visual check before anything is written. If we find a problem, we tell you and stop.
Original file read and stored locally and off-site, custom calibration written for your vehicle, then flashed with a stabilised power supply.
Tested on local roads with boost and fuelling verified, adaptations reset, then a proper walk-through of what changed before we leave.
What you actually get
No drop-off, no collection, no waiting room. The vehicle is back in service the moment we finish.
The person writing your file is the person standing next to your car. Ask anything you like.
Genuine tools, stabilised power, and full diagnostic capability — all in the van.
Evenings and Saturdays are normal for us, because that is when most people are free.
Travel is included across the standard South Wales zone. Longer trips are quoted upfront with no surprises.
We can work through several vehicles in a single yard visit and keep every file logged by registration.
The detail
Mobile tuning done properly is a discipline of its own. Here is exactly how the service works and where it reaches.
Professional programming interfaces covering OBD, bench and boot-mode access, a stabilised power supply to hold voltage rock steady through the flash, diagnostic equipment for live data and actuator testing, and the full calibration toolset with off-site file backup. Nothing is left behind at a unit.
The single greatest risk during an ECU write is a voltage drop. We never flash a vehicle on a marginal battery. A stabilised supply is connected for the duration, and if a battery is genuinely on its way out we will tell you before starting rather than risk a corrupted ECU.
Any driveway, car park, farm yard, industrial unit, depot or roadside spot where the vehicle can sit safely and legally for an hour or so. Rain is not a problem. We work all year round across the valleys.
A file is not finished until it has been driven. We use local roads with a proper hill and a proper straight, checking boost delivery, fuelling, exhaust temperature and gearbox behaviour. If something needs adjusting, it gets adjusted before we leave.
Standard zone with no callout fee covers Merthyr Tydfil, Cardiff, Swansea, Newport, Bridgend, Caerphilly, Port Talbot, Chepstow and Cwmbran and the surrounding valleys. Beyond that — Carmarthenshire, Brecon and the borders — we still travel, with any travel cost agreed in advance in writing.
For businesses we schedule a single visit and work through the vehicles in sequence, logging each original and tuned file against its registration. Most operators lose no productive time at all because we work around the shift pattern.
Support does not end when the van pulls away. Your files stay on record, revisions are free within the guarantee period, and if you need the original restored for a dealer visit we will come back out and do it.
Where we cover
Mobile to your driveway, workplace, yard or farm — anywhere in South Wales.
