Car Engine Tuning FAQ

How does the performance tuning work?

Simply expressed, the output increase is achieved by adjusting the quantity of fuel-air mixture and the ignition time. In this process the injectors play a major role, they control the amount, timing and fuel injection pressure. Vector tuning module picks up the control unit’s data, processes and optimizes it through Vector microprocessor and then sends the modified value to the central system, in Electronic control unit (ECU). ECU collect this data and continues to operate with engine motor.

Does the performance improvement leads to an increased fuel consumption?

Vector module regardless of the increase of engine power doesn't increase fuel consumption, the secret is in the increased torque.

Will my vehicle emit much more particle emissions/smoke after tuning?

The power increase doesn't affect the change in particle emissions.

To increase engine performance we also recommend to install a sport air filter.

Will the maximum speed increase?

The increase in power is achieved by increasing the torque in the lower and medium speed range. Therefore, maximum speed is increased in practically all vehicles of approximately 5 to 10 km/h depending on the tolerance of each vehicle.

Why should the supplementary electronics also be set and tuned for each vehicle?

It's known in practice that there are minor deviations in technical features of two same vehicles depending on the their maintenance, mileage, fuel quality and the method and place of use. For these reasons, the default setting of Vector modules can't achieve the greatest possible improvement in engine performance.

By adjusting the additional system management from Vector company, optimal effect can be achieved on certain types of vehicles. Electronics can be adjusted depending on the needs and desires of the customer.

How long is the warranty for the functionality of the tuning box?

For the original Vector module that is properly installed and configured for your vehicle we provide 24-month warranty. To achieve this condition it's necessary to have a bill of purchase!

Can the change be noticed externally?

The vehicle from outside is not different from serial model. Power change can be determined only on the rollers for testing engine, Dyno.

Might the car heat up more than before?

The temperature is increased very slightly (only at full throttle). For example, in the case of an Audi TDI at constant full throttle, the increase will be 8 degrees.

Will the car have a shorter service life after the alteration?

With tuning, the increase of the engine power is achieved by optimizing the engine and by using the tolerance of different parts of the engine, and at the same time does not fall within the limits of engine operation. According to previous experiences, range of diesel engine efficiency goes up to 60% of the initial value. For normal use of the vehicle, regular oil changes and regular service, engine life is not reduced. Only if you drive in constant ‘sport’ style, you will have to change car oil more frequently than recommended by your car producer.

Why doesn’t the manufacturer just set the vehicle to the optimal value?

The manufacturer is building a car for the global market, which must meet various requirements. This is primarily related to the weather conditions, fuel quality and method of exploitation of vehicles.

Do you have to change the brakes after engine tuning?

Not necessary.

Are there any particularities for an automatic vehicle?

A vehicle with automatic transmission is automatically adjusted to the new conditions.
