Live Dyno Calibration

On arrival, the vehicle is carefully positioned and secured on our rolling road dyno using controlled load-rated strapping to ensure complete stability during testing.

Tyre pressures are checked and drivetrain alignment is verified to guarantee accurate and repeatable load application throughout the calibration process.

High-capacity cooling fans are positioned to simulate real-world airflow across the intercooler and radiator system, maintaining consistent intake and coolant temperatures under sustained load.

This controlled setup ensures stable operating conditions and repeatable dyno data before any calibration development begins. All xDrive and AWD vehicles are run on our mechanically linked 4WD dyno.

Before any calibration work begins, a comprehensive diagnostic assessment is carried out to verify that the engine and drivetrain are functioning correctly under real-time conditions.

We evaluate:

• Stored and pending fault codes
• Boost control response and deviation
• Fuel rail pressure consistency
• Injector balance and correction values
• Exhaust gas temperature modelling
• DPF status and regeneration data (where applicable)
• Gearbox adaptation and torque management data (if fitted)

Live data is monitored under controlled load to ensure all critical parameters remain within manufacturer tolerance before performance development starts. If any irregularities are detected, they are addressed prior to calibration.

This stage ensures the vehicle provides a stable and reliable foundation for safe performance enhancement. We will not proceed with calibration if the vehicle is not in a fit state.

Initial dyno runs are performed to establish a controlled reference point before any changes are made to the calibration.

• Measured: true wheel horsepower & torque
• Analysed: factory torque delivery characteristics
• Recorded: boost curve behaviour
• Verified: AFR and fuelling consistency

This baseline highlights any inconsistencies in factory torque modelling. Unlike estimated dashboard figures, dyno testing provides measured data: this is your car’s true starting point.

Using the baseline data collected, calibration development begins.

This is not file uploading. Every change is made live, tested immediately, and refined in real time.

We progressively adjust:

• Torque request and torque limiter strategy
• Boost control mapping
• Rail pressure and injection duration
• Throttle sensitivity
• Gearbox torque intervention logic (where fitted)

All changes are applied incrementally and tested immediately on the dyno while monitoring exhaust gas modelling, boost deviation, fuel pressure stability and transmission torque handling.

Multiple validation dyno runs are performed to confirm the calibration is delivering consistent, controlled performance across the full rev range.

• Confirmed: smooth torque ramp-in
• Confirmed: controlled mid-range delivery
• Confirmed: stable boost under sustained load
• Confirmed: clean shift behaviour under torque

Fine refinements are applied where necessary. The goal is a car that feels factory integrated, not artificially aggressive: consistent, repeatable performance you can use every day.

Once development is complete, final validation runs are recorded. You leave with full documentation of everything measured on the day.

• Before & after dyno graphs showing the full power curve across the entire rev range
• Wheel horsepower measured on the rollers, with the flywheel figure calculated from the drivetrain losses measured on the same run
• Measured torque increase with before and after comparison across the rev band

All results are based on controlled dyno measurement. There is nothing to hide when everything is built and proven on the rolling road in front of you.
