The mobile workshop
A proper workshop — it just happens to have wheels
The van is fitted out as a workshop: a lit workbench, mains power, a stable battery supply for your car while it is being written, and the Alientech tools that read and write the engine computer.
Some engine computers have to come out of the car and be read on the bench. That happens in the van too, so your car never leaves your sight.
- Alientech KESS3 for OBD, bench and boot reading
- Battery support throughout — no flat-battery risk
- Dealer-level diagnostic scanner
- Your original file saved before anything is written
How a mobile remap works
Four steps, usually one visit
- 01
Send us the reg
Book online, call or WhatsApp. We confirm your ECU, the expected gains and the price before we travel.
- 02
We arrive and check
Battery support on, full fault scan, and a quick look at the things that matter — no point tuning a car that needs a repair.
- 03
Read, save, write
Your original software is read and saved. The new file is written for your exact engine and flashed.
- 04
Road test together
Faults cleared, a road test with you, and we only leave when you are happy with how it drives.
Real figures, real cars

Questions people ask
Do you really come to me?
Yes. Everything is done from our fitted van at your home, your workplace or a show — it carries its own power, battery support and tools.
How long does a remap take?
Most Stage 1 remaps take one to two hours from arrival, including a health check before and a road test after.
What happens to my original file?
It is read and saved before anything is written, so your car can always be returned to standard.
Which vehicles can you remap?
All makes of cars and vans — diesel and turbo petrol. Send us the reg and we will confirm your ECU and the expected gains before we travel.
Where do you cover?
Kent, South-East London and East Surrey, from our base in Tatsfield near Westerham. East Kent is covered on planned route days.
Do you do DPF, EGR and AdBlue work?
We diagnose and fix those faults on road vehicles. Removal solutions are supplied only for off-road, motorsport and export use, as UK law requires.
