Our technicians will create a communication connection with your engine control unit (ECU). Communication with the ECU is done via a OBDII diagnostic connector or via a direct connection to the ECU hardware (according to the vehicle and control unit type).

Subsequently, engine maps from ECU are loaded and a full data back-up is performed. After that, we carry out a data optimisation process and, depending on the type of software, an engine map adjustment.

These maps are searched for by hand. We do this to avoid inaccurately labelling individual data, which may happen when using programs based on an algorithmic search. This way, the tuning is always perfectly safe.

After the optimisation process, the adjusted software is loaded into the engine control unit. Your software is therefore always adjusted to your particular needs.

Our tunings are always tested over the long term and never exceed the safe limits of an engine or its parts. One important aspect determining the way the tuning will be done is the type of transmission (automatic/manual).

If a vehicle is equipped with automatic transmission, it is necessary to adjust the engine maps responsible for shifting the automatic transmission.

We guarantee the safety of Quantum Chip Tuning and never make any adjustments that would exceed the power reserve of an engine or its parts.

It is very easy to find tuning providers promising unrealistic enhancements for individual vehicles. In most cases, this is simply a case of making fraudulent claims. However, we have encountered tuning offers that would actually harm the engine and cause, for instance, massive clutch or turbocharger wear.

Car manufacturers usually produce one vehicle that is distributed across the world. Different countries have different emission standards, however, and conditions are also very diverse (extremely high or low temperatures, humidity, different types of fuel).

Even so, these tunings are indeed done by the manufacturers themselves. For instance, the 1.6TDi-CR manufactured by the Volkswagen Group (Škoda, VW, Audi and Seat) has different performance versions of the same engine – 55 kW, 66 kW and 77 kW.

Software adjustment/chip tuning is the optimisation of engine maps within the ECU. Data are loaded into the flash memories of the engine control unit – these memories are external or internal, and then directly into the microprocessors.

The car’s dynamics and driving characteristics are defined according to the map patterns that are stored in the ECU. So, if, for instance, you are driving down the motorway at 100 km/h and sharply accelerate (when you press the pedal to the floor) the control unit will load its data and, according to your current gear, speed and accelerator pedal position, determine the torque curve.

This will set the right amount of injected fuel, how much air in the turbocharger is needed, and carry out many other settings. The tuning process optimises this data, improves engine performance curves and ensures more efficient fuel economy.

Your satisfaction is our greatest pursuit. Therefore, we offer an unrivaled 30-day trial period for you to test our tuning.

After we have finish your chip tuning, you have 30 days to test it and within that time, without giving any reason, you can come back and we will re-load your previous software and refund your money.

If the vehicle is still covered by warranty, there are a couple of ways to proceed. The first way is to contact your car-dealer and ask them their view on chip tuning the vehicle. It is also important to mention that the tuning would be done by our company.

Quantum Tuning is one of the largest vehicle tuners in the world and our reputation is carries considerable weight in the automotive world.

The second option is to proceed with the tuning and if there are any issues forcing you to take your car back to your dealership for warranty reasons, we can reset your car to its original state.

Data back-up is part of the whole vehicle tuning process. Every customer receives the back-up of their ECU on a data carrier.

Of course. It is possible to restore your vehicle back to the factory/original settings at any time.

The driving dynamics, agility, and drive comfort of the vehicle, together with its better fuel economy, are the main reasons why you should want to have your engine maps in the ECU adjusted.

Overtaking another vehicle in difficult conditions, on twisty B-roads and stretches with reduced visibility, or the need to quickly accelerate from an intersection are other reasons you could do with a performance boost.

Yes, the upgrade depends on the type of control unit and firmware. This kind of tuning involves adjusting parts of the engine to the original values of the superior performance version.

However, the adjustment is always done within your software type, i.e. it is customised to fit your vehicle.

Add-on control units, like PowerBox-type units, work by misleading your engine control unit, using false information about turbo or fuel pressure, for example.

Not that all PowerBoxes are bad, but most of them are cheap single-channel versions that can never replace comprehensive ECU software tuning.
