The complete setup matters

A list labelled Stage 2 is not enough to describe a vehicle. Changes to forced induction, intake, cooling or other components may change the calibration requirements. Record manufacturers, exact component names and any existing measurements. This helps establish whether the requested work suits the current setup and which details are still needed.

Document modifications clearly

Your request should include the readout, control unit identification, specified fuel, transmission variant and a complete description of the modifications. Any existing third-party calibration must also be stated. The review establishes a traceable starting point; it does not replace an inspection of the mechanical condition. A project with unresolved faults needs diagnosis first.

Validation is part of the project

With modified hardware, assessment should extend beyond a single power target. Behaviour under load, temperatures and coordination between engine and drivetrain also matter. The measurements required depend on the project and should be agreed in advance. Software modifications do not approve every hardware combination; the acceptability of the complete conversion must be checked separately.

Frequently asked questions

Can I order Stage 2 without details of my modifications?

A meaningful assessment requires specific information about the installed hardware. Without it, the conditions for which the file should be calibrated remain unclear. Include the component list and any existing measurement data in your request.

Is Stage 2 automatically better than Stage 1?

The right calibration depends on the vehicle and the goal. A near-standard vehicle and an extensively modified one have different requirements. The stage label alone is neither a measure of quality nor a statement about durability.
