About Custom Remapping Ltd

Custom Remapping Ltd is a mobile ECU remapping specialist based in Alexandria, West Dunbartonshire, covering Glasgow and a wide area across Scotland. We provide a fully mobile service for private cars, fleet vehicles, HGVs, and agricultural machinery — bringing professional vehicle tuning directly to your home, workplace, or depot.

Who We Are

Custom Remapping Ltd was built on a simple idea — remapping should be convenient, honest, and tailored to the vehicle in front of us. Rather than asking customers to travel to a fixed location and wait around, we bring our equipment to you, wherever you are across Glasgow and Scotland.

Every remap we carry out is bespoke. We don’t rely on generic, off-the-shelf software files. Instead, every map is calibrated specifically to the vehicle’s make, model, engine variant, and the goals of the person driving it — whether that’s outright performance, better fuel economy, or a balance of both.

What We Do

We work across a wide range of vehicles and industries, including:

Private Cars

Remaps for everyday drivers looking for more power, better throttle response, and improved fuel economy.

Fleet Vehicles

Helping businesses across Scotland reduce running costs and improve performance across their vans and company cars.

HGVs

Mobile remapping for hauliers and operators, improving torque, fuel economy, and driver comfort on long-haul routes.

Agricultural Vehicles

Specialist remapping for tractors, telehandlers, and farm machinery across Argyll, Ayrshire, and Stirlingshire.

Vehicle Re-Commissioning

Restoring vehicles that have been previously modified back to a compliant, reliable standard.

Why Choose Us

We come to you. Our fully mobile service means no need to arrange transport or take time out of your day to sit in a waiting room.

Every map is bespoke. We write each remap specifically for the vehicle and the customer’s goals — never a one-size-fits-all file.

We back our work. Every remap comes with a 14-day money-back guarantee and a lifetime warranty on all software.

We’re experienced. We’ve worked on hundreds of vehicles across Glasgow and Scotland, building a reputation for honest advice and results that speak for themselves.

We’re flexible. Open 6 days a week, we fit around your schedule rather than the other way around.
