ECU Remapping
Professional vehicle software optimisation — vehicle-specific, checked before and after, and only carried out where your vehicle suits it.
Stage 1 ECU Remap
€229- Vehicle-specific ECU software optimisation
- Improved throttle response and drivability
- Pre-remap health checks and ECU software read
- Post-remap checks
Suits most standard turbocharged petrol and diesel cars in good mechanical condition. Compatibility and legal road-use compliance are confirmed for your vehicle before any work is booked.
Enquire about thisStage 2 ECU Remap
From €299- Calibration for supporting hardware upgrades
- Written for your vehicle's exact modifications
- Pre and post-remap checks
For vehicles with suitable supporting modifications (e.g. intake, intercooler, exhaust) that remain road-legal. Compatibility and legal road-use compliance are confirmed for your vehicle before any work is booked.
Enquire about thisTCU / Gearbox Remap
From €199- Automatic / DSG gearbox software optimisation
- Shift-point and shift-speed refinement
- Torque limits matched to the engine calibration
Only for gearbox controllers that support software reading and writing. Compatibility and legal road-use compliance are confirmed for your vehicle before any work is booked.
Enquire about thisECU + TCU Package
From €349- Engine and gearbox remapped together
- Calibrations matched to each other
- Pre and post-remap checks
For automatic vehicles where both controllers are supported. Compatibility and legal road-use compliance are confirmed for your vehicle before any work is booked.
Enquire about thisEconomy Remap
From €199- Calibration focused on efficient everyday driving
- Smoother low-rev torque delivery
- Suited to commercial and high-mileage vehicles
Real-world economy depends on vehicle, load and driving style; we don't promise fixed savings. Compatibility and legal road-use compliance are confirmed for your vehicle before any work is booked.
Enquire about thisFinal price confirmed after your vehicle is assessed. Every remap is checked for compatibility and legal road-use compliance first, and we don’t quote horsepower or torque figures before that.
Plain-English guide
Understanding ECU remapping stages
Not sure which option suits your car? Here's what each one actually means.
Stage 1 Remapping
€229Software optimisation using your vehicle's original hardware.
- Improved engine performance and torque where appropriate
- Sharper throttle response
- Calibration written for your specific vehicle
- No hardware modifications normally required
For mechanically healthy vehicles that meet compatibility requirements. Actual improvements vary with the vehicle, engine, ECU and its existing condition.
Stage 2 Remapping
From €299A more advanced calibration for vehicles with suitable supporting hardware.
- Requires an assessment of your existing modifications
- May need an upgraded intake, intercooler, exhaust or other components, depending on the engine
- Additional mechanical and compatibility checks
Stage 2 isn't simply a stronger Stage 1 — it's designed for vehicles already fitted with the right supporting hardware. Not every vehicle can safely support it.
Economy Remapping
From €199Calibration focused on efficiency and smoother power delivery.
- Smoother, more relaxed everyday driving
- Results depend on driving conditions and vehicle condition
- Must stay compliant with emissions and road-use requirements
Fuel savings are not guaranteed.
TCU / Gearbox Remapping
From €199Optimisation of compatible transmission control units.
- Potential improvements to shift behaviour
- Torque management matched to the engine
- Compatibility depends on gearbox type, software version and condition
Not every gearbox supports tuning.
ECU + TCU package — engine and gearbox together: From €349
Is your vehicle suitable for remapping?
Tell us a little about your vehicle and our team will assess its compatibility and available tuning options.
We don't look up your registration automatically — your answers go straight to our team. No vehicle is confirmed as compatible until we've checked its ECU hardware, software version and mechanical condition.

Before you book
Road-use compliance
We only advertise and carry out road-use remapping that complies with applicable Irish and EU requirements.
No emissions-system deletes
We don't provide DPF or EGR deletes, emissions-system defeat devices, or software modifications intended to circumvent emissions controls on road-going vehicles.
Warranty, insurance & emissions
Remapping may affect manufacturer warranties, insurance and vehicle emissions compliance. Please tell us your vehicle's warranty, finance and NCT status before we confirm any work.
Vehicle suitability
Suitability depends on the vehicle, engine, ECU software and mechanical condition. Every job is assessed first, and we can't guarantee that every ECU can be programmed.
Remapping FAQs
Ask about your vehicle
Send your vehicle details and we'll tell you whether remapping is suitable, what it would involve and what it costs — before anything is booked.
ECU remapping and diagnostics are appointment-based. We assess your vehicle and your location first — we can't promise that every job can be carried out at your home or workplace, and sending a form doesn't confirm an appointment.
