Stage 1 ECU Remapping

Quantum Tuning Stage 1 ECU Tuning File is performed by optimizing the performance of a vehicle by modifying the engine management system (ECU). Software modification takes place whereby engine parameters such as throttle pedal injection, torque limiters, turbo charge pressure, fuel / air ratio and fuel pressure are readjusted within safety limits.

Stage 2 ECU Remapping

Quantum Tuning Stage 2 Chiptuning File starts with a STAGE 1 TUNING but adds additional modifications like Decat / EGR / DPF / VMAX / DTC removal. If you want more power for racing dynamics, we will reprogram the vehicle's ecu with Quantum Tuning Stage 2 Tuning File within legal limitations & safety limits after diagnosing the vehicle & it's condition

Stage 3 ECU Remapping

Quantum Tuning Stage 3 ECU Tuning File typically count by most people as suitable only for track days and motor sports However, stage 3 ecu tuning needs adjustments to other engine components such as intercoolers, exhaust etc. it is important to weigh the benefits and risks carefully. It is also important to choose a reputable ecu tuner who can do the job correctly.

Chip Tuning Files Services

Speed Limiter Solution

A speed limiter is a governor used to limit the top speed of a vehicle. For some classes of vehicles and in some jurisdictions they are a statutory requirement, for some other vehicles the manufacturer provides a non-statutory system which may be fixed or programmable by the driver. Quantum Tuning offers the solution to adjust, disable or remove the vehicle speed limiter from your vehicle to any desired value (within legal limitations)

VMAX Solution

As the name implies It is also know an VMAX OFF, this option allows the tuner to activate or deactivate the speed limit that manufacturers enter in many cars. In this way, this limitation is eliminated by the switch functions to activate or deactivate it. Quantum Tuning offers the solution by altering or adjusting the settings of a vehicle's Engine Control Unit (ECU) to improve several areas of the vehicle’s performance. By overwriting the existing settings with new quantum tuning's custom made ecu program (within legal limitations)

COD / ACT Solution

Cylinder on Demand (COD) / Active Cylinder Technology (ACT) within the ECU software. Quantum Tuning offers the solution by altering or adjusting the settings of a vehicle's Engine Control Unit (ECU) to improve several areas of the vehicle’s performance. By overwriting the existing settings with new quantum tuning's custom made ecu program (within legal limitations)

MIL Codes Solution

The check engine light, often referred to as the Malfunction Indicator Lamp (MIL), allows the PCM to alert the driver that an emissions related problem has occurred or is currently occurring. Quantum Tuning offers the solution by altering or adjusting the settings of a vehicle's Engine Control Unit (ECU) to improve several areas of the vehicle’s performance. By overwriting the existing settings with new quantum tuning's custom made ecu program (within legal limitations)

BMW / VAG Display Recalibration

Cars that have bmw/mini sport gauges in central module display with HP/NM can now also be raised so final customers will now be able to see that their car was “really” tuned by checking the new values on sport gauges. Quantum Tuning offers the solution by overwriting the existing settings with new quantum tuning's custom made ecu program (within legal limitations)

Start/Stop Disable

Start/Stop or Autostop or ESS, or Idle Stop & Go is a system on a majority of modern cars which cuts the engine off when the car is stationary in order to reduce fuel consumption and emissions, some likes it, others hate it. For those of you that hate it Quantum Tuning can offer a start-stop disable service. By changing the coding inside the ECU we can fully deactivate the start/stop system. All hardware can remain in place, it will simply be electronically disabled, giving you back full control of your engine (within legal limitation)

ECU Checksums Correction

A checksum is a value that is calculated from a block of digital data with the scope of being used in the future to verify if this data has been modified in any way. So basically if you change any of the maps in your cars ECU the currently saved checksum/s will not be correct and your car in most cases will not start

Performance Tuning Files

Performance ECU tuning is the process of modifying the software in your vehicle’s Engine Control Unit (ECU) to optimize its performance. Basically, it’s like tweaking the internal settings of your car’s computer to potentially unlock more power, improve throttle response, or even increase fuel efficiency.

EGR Solution

Exhaust gas recirculation (EGR) is an emission control technology allowing significant NOx emission reductions from most types of diesel engines, To prevent future EGR valve problems or malfunctions and internal engine pollution, Quantum Tuning offers the solution by overwriting, disabling or deleting the existing settings with new quantum tuning's custom made ecu program (within legal limitations)

DPF Solution

A diesel particulate filter (DPF) is part of a diesel car's exhaust system that's designed to filter out harmful soot. It is a device fitted to the exhaust system of modern diesel vehicles to reduce emissions and meet European emission standards. It does this by trapping Soot (Particulate Matter - PM) from the exhaust gasses as they flow out of the exhaust.

LAMBDA / O2 Solution (DECAT)

When decatting a petrol vehicle it is likely an engine management light will be illuminated and a fault code for cat efficiency will be stored inside the ECU memory. By careful recalibration of the Engine Control Unit (ECU) data, we can disable or delete the function of the lambda OR O2 sensor (within legal limitations)

Original ECU Files

Quantum Tuning has one of the largest Original ECU Files or often called as ORG Files database, which you can rely on, Register yourself & Search your vehicle or ECU from our tuning files database

Hot / Cold Start

The hot/cold start feature is an optional feature in Compustar and Arctic Start remote starters that will allow your vehicle to automatically remote start when the temperature reading in the vehicle cabin reaches a set temperature, For those of you that hate the Start/Stop technology, we can fully deactivate this feature within the ECU software.

Performance Gauge

Performance Gauge is a Multi-Function digital vent gauge displays critical vehicle metrics like coolant temp, intake air temp, ignition timing, speed, RPM with shift light, and battery voltage - as well as peak recall all modes. Quantum Tuning offers adjustment of the digital performance meters (BMW / Mini / VAG ) that display the power and torque in real time.

Engine Rev Limiter

A limiter prevents a vehicle's engine from being pushed beyond the manufacturer's limit, known as the redline (literally the red line marked on the tachometer). Quantum Tuning offers solutions to adjust the engine speed limiter from your engine to any desired value (within legal limitations)

Hard Cut - Rev Limiter

Hard Cut Limiter cuts fuel at the set RPM limit. This changes how the engine behaves and changes the sound of the vehicle at the RPM limit. With the manufactures RPM limit, a diesel car will hit the limit and will stay at the exact point until the driver takes his foot off the gas pedal. Quantum Tuning Motorsport rev limiter allows to reach the actual engine speed limiter without prelimiting the engine power output first. This way all the engine power stays available which allows better acceleration and a true motorsport experience (within legal limitations)

Swirl Flaps Intake

Swirl flap position is adjusted by an electrical or vacuum-actuated servo mechanism which is under the control of the engine management system (ECU). In a typical implementation the flaps will be closed at idle speed, creating additional turbulence in the intake. As engine speed increases, the flaps are gradually, they are parallel to the airflow and present virtually no resistance. When removing the intake swirl flaps it is important to disable the related swirl flap functions correctly within the ECU software to prevent associated fault codes (within legal limitations)

Adblue (SCR) Solution

Selective Catalytic Reduction (SCR) also known as Adblue System, which is a technology used for reducing nitrogen oxides (NOx) from the exhaust gas of diesel engines. It's based on AdBlue - also called diesel exhaust fluid - a 32.5% urea solution in purified water, which is injected into the exhaust pipe. By careful recalibration of the Engine Control Unit (ECU) data, we can disable or delete the DTC's & various functions of the Adblue OR SCR System (within legal limitations)

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

We have an huge amount of technical experience and expertise and have used this to build a suite of IMI Approved training courses to support our dealer training and development program.

  • Basic OBD Programming
  • Advanced Bench Programming
  • Advanced K-Tag Programming
  • Chip Tuning

You cannot run an effective remapping business without thorough training, giving you detailed and expert knowledge. We have seen countless people over the years that have experienced what we call “black box syndrome”. Basically, they have brought a tool from a cheap supplier, who training extended to which website to download the software from and that’s it. Then first few vehicles come along, they don’t know what do, maybe even hit a problem, lose confidence and the ‘cheap’ black box sits in the corner gathering dust, worthless.
