Car manufacturers today build only a few base engines and differentiate power partly through electronics alone: same engine, partly identical components — but different software. Manufacturers also have to meet many safety and emissions requirements for different markets, which is why the true potential of the engines usually remains unused.
The ECU data is read out via the OBD port or directly at the control unit using our tuning tools and then optimised individually. We use the existing power reserves intelligently while respecting the limits that protect the engine — the factory engine protection systems are always preserved.
The stages depend on the mechanical configuration of your car. Every tuning file is calibrated for the corresponding fuel octane rating: higher-octane fuels tolerate more advanced ignition timing, higher boost levels and leaner mixtures. For petrol engines we generally recommend — regardless of tuning — not to fill up below 100 octane.
Developed for vehicles with stock engine components — no parts need to be changed. All Stage 1 calibrations were developed both on the dyno and on the road to make sure the modifications run perfectly.
Torque is adapted to the gearbox type (manual and automatic differ). Component-protection limiters are kept, the limp-home function stays active. Unnecessary factory restrictions, fuel limiters and unwanted torque limits are removed. Optimised combustion values deliver ideal fuel consumption with better power and sharper throttle response.
Stage 2 requires at least a downpipe with a sports catalyst; on some vehicles minor intake modifications make sense. Depending on the car we also recommend a larger intercooler: cooler charge air means higher air density and more oxygen in the combustion chambers.
At Stage 1, exhaust back pressure and exhaust gas temperatures usually cap the power — exactly these values are reduced for Stage 2 by the adapted hardware. We discuss the required hardware modifications individually with you and match the software precisely to them.
If Stage 2 is not enough, we are happy to help with a turbo upgrade. Which hardware changes are required in addition to the upgrade turbo and the Stage 2 modifications is discussed case by case — depending on your power target. For a correct calibration on existing hardware, all data must be specified exactly.
Stage 3 calibrations require logging tools, a dyno and deep expertise to develop clean combustion and a safe long-term power level. If amateurs get to work here, the engine can be damaged irreversibly — fine-tuning on the road is essential.
