Stage 3 is a vehicle-specific calibration prepared for vehicles that have had comprehensive hardware conversion, with main components such as the turbo, injectors, fuel pump or intercooler replaced.
What is Stage 3?
Stage 3 is the most comprehensive of the performance levels. At this level the vehicle has gone far beyond factory hardware: a larger turbo, higher-flow injectors, a reinforced fuel system or a large-capacity intercooler are fitted. Because the factory software does not recognise these components, the ECU has to be recalibrated completely.
Why is a standard file not enough?
In Stage 1 and Stage 2, files can be prepared for certain hardware groups. In Stage 3 the fitted turbo model, injector flow, fuel pressure and other components are different on every project. That is why every job is an almost from-scratch calibration process; a ready-made file cannot be used on another project.
At this level, giving correct hardware information is critical for the safety of the result.
Information needed for Stage 3
- Make and model of the fitted turbo
- Injector model and flow rate
- Fuel pump and fuel system changes
- Intercooler, exhaust and air intake system details
- The current ECU file and any previous software
- Intended use (track, drag, daily)
Process
After your request is sent through the panel, our engineers review the hardware information and the file together. Where necessary, additional information and test results (e.g. logs) may be requested. Stage 3 projects usually do not end with a single file delivery; they may need iteration with test drives and feedback.
Things to note
- Make sure the mechanical components (gearbox, clutch, engine internals) can handle high loads
- Fuel quality directly affects the result at this level
- A dynamometer or controlled test environment is recommended
- The software needs to be reviewed again after every hardware change
Frequently asked questions
No. Because it depends on the fitted hardware, every project is prepared specifically for the vehicle.
It is not mandatory, but a controlled measurement environment is strongly recommended for a safe and efficient calibration.
Yes. Hardware details or test logs may be needed; this correspondence is carried out within the same request.
