Why Choose Our Specialist ECU Remapping in Swansea

Modern vehicles are built to meet global markets and emissions standards. As a result, manufacturers “de-tune” engines to fit regulations, climates, and insurance brackets. That means your engine could be holding back power it doesn’t need to.
Our custom remapping services allow you to:
  • Gain up to 50% more performance (varies by make/model)
  • Unlock fuel savings from better combustion efficiency
  • Customise engine behaviour to match driving style
  • Remove unwanted limitations
All maps are tailored to your vehicle, driving needs, and hardware condition.

What Is ECU Remapping & Chip Tuning?

Remapping refers to modifying the software within your vehicle’s Engine Control Unit (ECU) to improve performance, efficiency, or functionality. It’s the modern evolution of chip tuning, now applied to vehicles with re-programmable memory.
Remapping Benefits:
  • Enhanced throttle response
  • Improved torque and horsepower
  • Better fuel economy
  • Removal or adjustment of speed limiters
  • Support for vehicle ECU modifications in almost any way

Chip Tuning (Legacy Vehicles)

For older cars with one-time programmable chips, we provide physical ECU chip removal, data extraction, and programming. Where required, we use ultraviolet erasing or chip replacement methods.
We also handle ECUs with high security protocols — accessing via bootmode to safely bypass manufacturer protections.

Our Remapping Process

If the ECU doesn’t start immediately, we troubleshoot and resolve it — our experience in ECU recovery sets us apart from less-qualified tuners.

Step 1: Vehicle Health Check

Scan for faults and assess system readiness

Step 2: Read ECU Data

Use industry-standard tools to extract your ECU file

Step 3: Modify Map

Tailor adjustments to your goals (power, economy, etc.)

Step 4: Write Updated File

Flash modified file back to the ECU

Step 5: Post-Tune Testing

Confirm results, verify system performance

FAQs: Remapping & Chip Tuning

Our remapping services start from just £100, depending on:
  • ECU type (newer ECUs are more secure and complex)
  • Required service (e.g., performance, eco, or limiter removal)
  • Vehicle condition or hardware upgrades
Performance/Economy Remaps: From £170
Custom Solutions: Quoted individually following inspection
No — not when done professionally. We take vehicle health seriously. Every remap is backed by:
  • Engine diagnostics and data logging before mapping
  • Software integrity checks post-flash
  • Manual recovery support if the ECU locks (common with newer ECUs)
We also recover many ECUs that were damaged by third-party tuners lacking our experience or tools. A remap will only cause issues if existing engine components are already compromised.
Chip tuning involves physically removing ECU chips on older vehicles. Remapping is software-based for modern cars.
Most can. Some very new or highly encrypted ECUs require specialist access. We’ll confirm this during inspection.
Not for basic remaps. But for advanced tuning (e.g., anti-lag), supporting mods may be needed.
Standard remaps usually take 2-4 hours.
