Not all vehicles are created equal — and neither should their tuning be.
If you’ve upgraded your car beyond stock, or simply want more control over how it performs, a custom remap is the smartest option. At Remaps Bristol, we build bespoke tuning solutions based on your exact goals, driving style, and vehicle setup.
Whether you’re running a hybrid turbo, a full exhaust system, uprated injectors, or even a forged engine, we’ll craft a custom ECU remap that brings it all together — safely and effectively.
What Is a Custom Remap?
A custom remap is a fully tailored engine tune, written specifically for your vehicle. Unlike generic “off-the-shelf” maps, it takes into account:
- Your vehicle’s exact hardware (intake, turbo, intercooler, exhaust, etc.)
- Fuel grade (regular, super unleaded, ethanol blends)
- Driving goals (performance, economy, or balance)
- Specific ECU data logs and real-time parameters
We extract your ECU’s software, review detailed data, and adjust everything from fuel delivery and boost pressure to ignition timing and throttle response.
The result? A remap that works perfectly with your unique setup — not just a one-size-fits-all file.
Who Needs a Custom Remap?
A custom tune is ideal for:
- Modified cars (Stage 2 or Stage 3 builds)
- Track cars or performance builds
- Vehicles with hybrid or bigger turbos
- Petrol cars with decats, upgraded injectors, or high-flow intakes
- Diesel vehicles with performance upgrades or heavy-duty towing use
- Anyone who wants maximum power while keeping reliability in check
If your car has had serious work done — or if you’re chasing a very specific outcome — a custom remap is the safest and most effective way to get there.
Benefits of a Custom Remap
You’ll feel the difference in every gear. Custom tuning gives you:
- Power and torque gains matched to your setup
- Improved turbo response and spool time
- Safer boost levels for your hardware
- Fuel trims and AFRs calibrated for your mods
- Smooth, progressive power delivery
- Reduced turbo lag or flat spots
- Improved drivability and control
Plus, we can fine-tune things like:
- Launch control
- Rev limiters
- Pops and bangs (if requested)
- Speed limiter removal (where legal)
This is performance on your terms — built around your car.
Custom vs Generic Maps – What’s the Difference?
Generic (or pre-written) maps are based on a standard model and can work fine for stock vehicles. But once you start modifying your car, they fall short.
A generic map:
- Assumes a factory-standard setup
- Doesn’t account for real-world sensor data
- Can push boost or fuelling too far for your parts
- Might underperform because it’s too conservative
A custom map:
- Reads live data from your car
- Responds to your hardware
- Matches your fuel quality and goals
- Is adjusted and refined based on actual driving results
If you’ve invested in performance parts, don’t waste their potential with a generic file.
What’s Included in a Custom Remap?
At Remaps Bristol, every custom tune includes:
- Full diagnostics and health check
- ECU read and backup
- Data logging (air/fuel ratio, boost, fuel trims, etc.)
- Tailored ECU calibration
- Post-map testing and refinement
- Ongoing support and map revisions (if needed)
If you’re local to Bristol, we also offer dyno sessions with trusted partners for advanced performance tuning.
How Much Does It Cost?
Custom remapping starts from £350 and varies depending on:
- Your vehicle
- The level of hardware modification
- Whether dyno testing is required
- Additional services (gearbox tuning, pops and bangs, etc.)
We’ll always quote upfront, with no hidden charges.
If your build evolves over time, we also offer discounted remap updates when you change parts or upgrade your setup.
How Long Does It Take?
Most custom remaps take 2 to 4 hours, depending on the complexity of the setup.
If data logging or dyno tuning is required, it may take longer. We’ll let you know ahead of time and work around your schedule.
We can carry out most custom tunes at our workshop or arrange mobile visits for supported vehicles.
What Vehicles Can You Custom Tune?
We offer custom ECU remapping for a wide range of vehicles, including:
- Turbo petrols (VW, Audi, BMW, Ford, Mercedes, etc.)
- Performance diesels (BMW, VAG, Ford, etc.)
- Hot hatches, performance estates, and track builds
- Modified vans and pickups
- Cars with forged engines or hybrid turbos
Whether you’re tuning a Golf R, an M135i, a Focus ST, or a heavily modified van — we’ve done it.
Just send us your spec list and we’ll confirm what’s possible.
