The software of the control unit is replaced or tweaked so that your car puts out more horsepower and torque. Tuning can also lead to better fuel consumption. The car tuning experts first measure all the necessary data in the tuning workshop such as the power dissipation, torque and engine output to name a few, and then overwrite them for a balanced increase in power. It is particularly important that the safety functions of the control of the engine generally remain activated in order to protect the engine from possible damage.

Engine and gearbox tuning

If you want to go all out right away, you may get your own engine built directly by the tuning workshop. When building the engine, a good tuner only uses top-quality motorsport parts to make it stable and reliable.

When you tune your engine, it is also recommended to carry out an upgrade of the gearbox too.

In fact, torque readings, after the engine tuning, can be too high for the manufacturer original settings of the transmission which can result in limited torque and performance. This would make the engine tuning efforts vain.

Well done gearbox tuning would increase torque limits in the transmission which will “transmit” more power to the wheels. For this reason, it would be a good idea to install an upgraded performance clutch kit.

BeDI cleaning and Walnut blast

With a BEDI cleaning the tuner cleans the engine from carbon residues, which often build up in engines with direct injection. These residues can result in relevant power loss. In order for the engine to get fit again, the tuner frees the combustion chambers, intake paths, valves, EGR valves, idle controllers and the throttle parts from the deposits using chemicals.

A more efficient way has now been found and it is called walnut blast. The name is pretty self-explanatory. Crushed walnut shells are blasted through the engine using compressed air. The downside of this method is that not all the previously mentioned parts of the engine can be reached so it is often recommended to carry out both a walnut blast and BeDI cleaning in combination to achieve best results.

Connecting rods

The connecting rods (or con rods) should always be inspected in order to prevent piston damage. In the best tuning workshops, the technicians can measure and angle the con rods so that you can continue to achieve full performance in the future. When the vehicle is being setup to achieve very high performance, with a big increase from the manufacturer specs, it is recommended to replace the con rods with upgraded ones, made from more resistant materials that can better support the increased power.

Injectors upgrade

The best car tuning workshops can also carry out the testing and cleaning of high-pressure injectors. Optimal cleaning with a nozzle test bench is usually sufficient to restore a smooth running of the engine and get a better fuel consumption.

Most of the stock injectors can support some light tuning but if you want to go a step forward, you’ll need to upgrade to bigger injectors. Please note that we’re going into the racing world here which means that you might start experiencing some idling or low-speeds issue. 

When upgrading the fuel injectors, you should be looking into upgrading the fuel pump too, otherwise the stock fuel pump might not be able to support them.

Conclusion

In this article we went through the main and most common performance upgrades but keep in mind that almost every car component can be upgraded to achieve better performance and the limits solely depend from the budget.
