CUSTOM ECU CALIBRATION
Custom ECU Tuning. Developed With Data.
Custom Stage 1, Stage 2 and Stage 3 ECU calibration backed by professional road logging, live-data analysis and performance reporting. We analyse how the vehicle behaves under load, refine the calibration where required and validate the finished result.

PERFORMANCE TUNING — REDEFINED
A Remap Should Be More Than Uploading a File
Modern ECU tuning involves torque modelling, airflow, turbocharger control, fuelling, thermal protection, gearbox interaction and numerous calculated limits.
Our approach is to understand the vehicle first and calibrate it appropriately rather than chase a headline dyno number.
Measure first. Calibrate second. Validate afterwards.
PERFORMANCE LEVELS
Stage 1, Stage 2 & Stage 3
The stage describes the level of hardware and calibration required. The actual calibration is developed around the individual vehicle, its ECU strategy, condition and supporting hardware.
STAGE
1
Custom Stage 1
Performance calibration for an otherwise standard or near-standard vehicle, designed to improve usable power, torque and response while respecting appropriate hardware and thermal limits.
- Custom ECU calibration
- Torque strategy optimisation
- Boost control refinement
- Airflow and fuelling assessment
- Road logging where appropriate
- Post-calibration validation
OEM / NEAR-OEM HARDWARE
PERFORMANCE HARDWARE
STAGE
2
Custom Stage 2
Calibration developed around supporting performance hardware. Hardware configuration, airflow capability, exhaust flow and thermal behaviour are considered during development.
- Hardware-specific calibration
- Custom boost strategy
- Torque model development
- Airflow and fuelling analysis
- Thermal behaviour monitoring
- Calibration revisions where required
MODIFIED HARDWARE
STAGE
3
Bespoke Stage 3
Calibration for significantly modified vehicles where upgraded turbochargers, fuelling changes and supporting hardware require software developed specifically around the build.
- Hybrid / upgraded turbo setups
- Injector and fuelling upgrades
- Bespoke torque architecture
- Custom boost control development
- Repeated road-data analysis
- Revision-based calibration process

CUSTOM MEANS CUSTOM
The Stage Number Is Only the Starting Point.
Two vehicles with the same engine can respond differently because of mileage, ECU software version, hardware condition, modifications, fuel quality, gearbox configuration and operating conditions.
The calibration should reflect the vehicle in front of us — not simply the engine code written on a database.

See What the Vehicle Is Actually Doing.
During suitable tuning and diagnostic sessions, live ECU data can be recorded while the vehicle is operating under representative load.
This gives us visibility of the control systems behind the performance rather than relying entirely on subjective road feel.

Your Tuning Session Can Produce More Than a Receipt.
Suitable logged runs can generate calculated performance information alongside the raw vehicle data captured during the tuning process.

Road-calculated power figures are not chassis-dynamometer measurements.
Estimated power and torque values are calculated from suitable logged vehicle data and operating conditions. They provide an additional calibration and comparison tool and are not represented as certified rolling-road dyno measurements.
DATA-LED TUNING
Why We Road Log
Logging allows calibration decisions to be based on how the vehicle actually responds under load, rather than relying only on theoretical figures or subjective road feel.
Stage 1 Validation
Check how the vehicle responds to calibration rather than relying solely on theoretical gains.
Stage 2 Development
Review the effect of supporting hardware and identify where the calibration requires refinement.
Stage 3 Development
Analyse heavily modified setups across repeated calibration revisions and logged runs.
Boost Control
Analyse requested versus actual boost and turbocharger control behaviour.
Intermittent Limp Mode
Attempt to capture faults under the operating conditions in which they actually occur.
Before / After Analysis
Compare suitable runs under comparable conditions to evaluate calibration changes.
ENGINE + TRANSMISSION
ECU and Gearbox Calibration Should Work Together.
On vehicles where transmission calibration is available, gearbox torque limits, shift strategy, clutch pressure and transmission behaviour may form part of the complete performance package.
OUR PROCESS
From Vehicle Check to Final Validation
The exact process varies by ECU platform and vehicle, but the underlying principle remains the same: identify, calibrate, measure and verify.
Vehicle Assessment
Identify the vehicle, ECU, software, hardware and requested outcome.
ECU Read
Original software is read using the appropriate OBD, Bench or Boot protocol.
Custom Calibration
The required Stage 1, Stage 2, Stage 3 or bespoke strategy is developed.
Road Test & Log
Relevant operating data is captured under representative load where appropriate.
Data Analysis
Vehicle behaviour is reviewed against the calibration objective and operating limits.
Refine & Validate
Calibration revisions are made where necessary before final validation.
PERFORMANCE TUNING FAQ
Common Questions
What is the difference between Stage 1, Stage 2 and Stage 3?
Stage 1 is generally designed around standard or near-standard hardware. Stage 2 is calibrated around supporting performance modifications. Stage 3 is a bespoke calibration for significantly upgraded hardware such as hybrid or larger turbocharger setups.
Is every remap custom?
The appropriate calibration strategy depends on the ECU platform, vehicle condition, software version, hardware and requested outcome. Modified and higher-output vehicles may require additional logging and calibration revision work.
Do you road log every vehicle?
Logging requirements vary by vehicle, ECU platform and service. Where appropriate, relevant parameters are recorded during road testing to validate performance or diagnose vehicle behaviour.
Are the performance figures the same as a rolling-road dyno?
No. Road-calculated figures are estimates derived from suitable logged data and operating conditions. They are useful for tuning analysis and comparison but are not chassis-dynamometer measurements.
Can you tune the gearbox as well?
Transmission tuning is available on many supported DSG, DCT, ZF and other TCU platforms. Compatibility is checked against the individual vehicle before quoting.
Should I tell my insurer about a remap?
Vehicle performance modifications can affect insurance terms. Customers should inform their insurer of relevant modifications and ensure the vehicle remains suitable and legal for its intended use.
