what we do


"Remapping" is a software change within a vehicle’s electronic control unit (ECU). We modify the operating parameters within the code (or ‘map’) to increase the vehicle’s performance and/or economy, without the need to change or add any hardware.

In many cases the map stored within the ECU can be accessed via the onboard diagnostics port (OBD) which is always situated within one metre of the driver’s seat. In some newer models the ECU needs to be removed for the modification to be carried out on the bench.

Once your IMI professionally certified Quantum dealer has taken a read of the ECU, they will upload it to our file writing team who will adjust the original calibration to maximise the vehicle’s performance, fuel economy, or a clever blend of both. Depending on the vehicle and ECU type the process normally takes less than an hour, although bench programming takes slightly longer.

Quantum Tuning works to the highest standards in all aspects of operation, including our business ethics. You can be assured of the following:

  • We will not overstate our figures to make them appear better than our competitors
  • We will not quibble over our 30-day money back guarantee
  • We will not raise your expectation of fuel savings to an unreasonable level
  • We will tell you if the improvements on your car are minimal and therefore not worth doing
  • We will never pass on or sell our customer data

ECU remapping involves reading the vehicle’s standard calibration map, and then adjusting various parameters such as fuel pressure, boost pressure (on turbocharged applications), ignition advance, and throttle pedal control – amongst others – to release the true performance of the engine.

When developing a new vehicle the manufacturer has to make a compromise on the state of tune to account for all driving conditions and regions. We take this initial mapping and alter the ECU software to safely gain power and torque, giving improved driveability and, in the case of diesel engines, enhanced economy.

Gearbox (TCU) Tuning

The DSG gearbox is a dual-clutch transmission that uses two separate clutches to shift gears quickly and smoothly. The software that controls the DSG gearbox is responsible for a variety of functions

DSG gearbox tuning from Quantum Tuning, also referred to as TCU Tuning or transmission tuning, involves making adjustments to the electronic control unit (ECU) software of the DSG transmission. The goal of DSG gearbox tuning is to optimise the transmission’s behaviour, performance, and characteristics according to the preferences of the driver.


Our ECONOMY REMAPPING works by improving the efficiency and power of the engine so that it doesn’t have to work as hard, in any given situation. Reduced throttle load and the ability to be in higher gears sooner and for longer results in marked fuel efficiency gains.

Customers will see FUEL IMPROVEMENTS of typically 8-10% on most diesel vehicles, often more when opting for our Quantum Green remap. Great for fleets too where the savings really count.

DSG TCU Tuning

DSG gearbox tuning is to optimise the transmission’s behaviour, performance, and characteristics according to the preferences of the driver. This process can be done by modifying the software parameters that control things like shift points, shift speed, launch control, and torque management. DSG tuning involves modifying this software to change the way it operates. This can be done by changing the shift points, the torque limit, or the way the gearbox responds to driver inputs.

VGS (7GTronic) Gearbox Tuning

Tuning a VGS transmission is the process of modifying the software of the VGS unit to improve its performance. This can be done to increase the speed of gear changes, improve fuel economy, or make the transmission more responsive. There are a few different ways to tune a VGS transmission. One way is to use a software tune, which modifies the firmware of the VGS unit. This can be done by a qualified Quantum Tuning dealer outlet.

DKG TCU Tuning

DKG stands for Doppel Kupplungs Getriebe and DCT is the English translation to double clutch transmission. DKG transmissions are typically found in high-performance cars, as they can provide faster acceleration and better fuel economy than traditional automatic transmissions. Tuning a DKG gearbox can offer a number of benefits, including: Faster gear changes, Improved fuel economy, More responsive transmission, Enhanced driving experience


Chip Tuning is simply remapping by another name, but involves the physical removal of the program chip from the main ECU in the vehicle and either re-programming or replacement with a new chip modified with a Quantum remap. Technology developments mean that Chip Tuning is rarer now, but is still the only way to programme certain vehicles. Nowadays most remaps are carried out via the diagnostic OBD2 Socket, or direct into the ECU using special adaptors on the bench.


Our performance remap software is developed to work on a standard vehicle maintaining manufacturer levels of reliability and original service intervals. Our Quantum Red calibration is specially designed for high power & ultimate performance.

Designed to fully unleash the full potential of your engine, Quantum Red™ can be installed on both petrol and diesel vehicles – enjoy the ride!

Would you let an unqualified doctor perform an operation on you? Or would you allow an untrained electrician carry out repairs in your home? The nature of this question can be applied should you decide to have your car remapped… this work should only ever be carried out by those with the necessary knowledge, skill, and experience - along with professional accreditation.

Quantum dealers go through rigorous and detailed training in all aspects of OBD and bench remapping to become professionally qualified ecu remapping technicians, certified by the Institute of the Motor Industry. This is the only such independently recognised remapping qualification and only Quantum dealers are currently able to acquire it. To help improve professional standards within the industry, we hope that other remapping companies will follow our lead and put their dealers through a similar, independently recognised, training programme.
