Mercedes-Benz Tuning Boxes & PedalBox – Diesel, Petrol, Hybrid & Electric

Looking for a tuning box or accelerator-response upgrade for your Mercedes-Benz?

DTUK supplies plug & play performance products for a wide range of compatible Mercedes diesel, petrol and hybrid models, together with PedalBox, PedalBox Pro and PedalBox EV applications.

Coverage extends across many generations of Mercedes-Benz, from A-Class, C-Class and E-Class models to CLA, GLA, GLC, GLE and selected AMG applications.

Because Mercedes has used many different engines, power outputs and electronic systems across these ranges, the exact products available depend on the individual vehicle and engine.

Select your Mercedes-Benz model below to see the DTUK products currently available for your exact vehicle.

Mercedes Diesel Tuning Boxes

Mercedes diesel engines have formed an important part of the DTUK range for many years.

For compatible diesel models, a DTUK tuning box works alongside the vehicle’s existing engine-management system rather than replacing the original ECU software.

Depending on the application, the DTUK system works with signals from multiple engine sensors to change the way the engine responds under load.

The aim is not simply to produce a headline peak-power figure. A well-matched system should provide stronger usable torque and power through the part of the rev range where the vehicle is normally driven.

That additional mid-range performance can be particularly noticeable during acceleration, overtaking and when maintaining speed on gradients.

Exact standard and expected tuned figures are shown on the individual DTUK application page for each supported Mercedes engine.

Mercedes A-Class, C-Class & E-Class Tuning

The Mercedes A-Class, C-Class and E-Class cover a huge range of engines and generations, including diesel, petrol, mild-hybrid and plug-in hybrid powertrains.

That means the model badge alone is not enough to identify the correct tuning product.

A Mercedes C220d, for example, can exist across different generations and engine-management systems, while A-Class and E-Class models have also been offered with numerous power outputs and engine configurations.

DTUK products therefore need to be matched to the exact model generation, engine and factory power output rather than selected from the badge alone.

Use the Mercedes vehicle selector below to identify the correct application for your car.

Mercedes CDI & d Diesel Tuning

Mercedes diesel model names have changed over the years, from traditional CDI badging to newer models using designations such as 200d, 220d, 300d and 400d.

Regardless of the badge used on the boot, compatibility is determined by the actual engine and electronic architecture fitted to the vehicle.

This is why two Mercedes models carrying similar diesel badges may require completely different DTUK systems.

The individual application page should always be used as the authority for current DTUK product availability and performance figures.

Mercedes Petrol Tuning Boxes

DTUK also supports a range of turbocharged Mercedes petrol engines.

Modern Mercedes petrol engines vary considerably in size, output, turbocharging and engine-management architecture, so there is no single generic Mercedes petrol tuning box suitable for every model.

Where a compatible DTUK tuning system is listed, the product is configured for that particular engine and vehicle application.

This includes selected Mercedes petrol models across the A-Class, C-Class, E-Class, CLA, GLA, GLC and other ranges.

Always select your exact vehicle to see what is currently supported.

Mercedes-AMG Tuning

Mercedes-AMG models combine high-output engines with sophisticated engine, drivetrain and transmission control systems.

DTUK offers products for selected compatible AMG applications, but availability varies between different engines, model generations and power outputs.

We therefore do not assume that a tuning system suitable for one AMG model will also work with another.

The individual vehicle application is the authority for current DTUK engine-tuning compatibility.

Where engine tuning is not available for a particular AMG model, a compatible PedalBox or PedalBox Pro application may still be available to change accelerator response.

Mercedes GLA, GLC, GLE & GLS Tuning

Mercedes SUV models such as the GLA, GLC, GLE and GLS are also represented within the DTUK application range.

These vehicles have been offered with diesel, petrol, mild-hybrid and plug-in hybrid powertrains, as well as numerous AMG variants.

Depending on the exact vehicle, available DTUK products can include an engine tuning system, PedalBox accelerator-response controller or both.

Select the correct model, generation and engine below rather than assuming that products are interchangeable between Mercedes SUV ranges.

Mercedes CLA & Compact Models

Mercedes compact models have developed rapidly over recent generations, with the A-Class, CLA, GLA and related vehicles sharing some technologies while still using different engines, outputs and electronic configurations.

DTUK supports a range of compatible applications across these model families.

As with the rest of the Mercedes range, compatibility must be checked against the exact engine and factory power output.

This is particularly important on newer vehicles, where similar model names can hide substantial technical differences between generations.

Mercedes Hybrid Tuning

Hybrid Mercedes models require an application-specific approach.

The presence of an electric motor does not automatically mean that the combustion engine can or cannot use a DTUK tuning system.

Compatibility depends on the exact engine, hybrid system and vehicle configuration.

Where DTUK lists a tuning product for a compatible Mercedes hybrid, the individual application page provides the current product and expected performance figures.

Other hybrid applications may still have a compatible PedalBox or PedalBox Pro even where no engine tuning system is listed.

PedalBox & PedalBox Pro for Mercedes-Benz

Engine power is only one part of how a Mercedes feels to drive.

Modern Mercedes vehicles use an electronic accelerator pedal, and the relationship between pedal movement and the response requested from the engine is controlled electronically.

PedalBox changes this accelerator-pedal characteristic, allowing the driver to choose a more responsive or more progressive feel without increasing the engine’s maximum power output.

Depending on the Mercedes application, DTUK may list PedalBox or PedalBox Pro.

PedalBox Pro adds features including wireless control and compatible app functionality, with additional functions available according to the product version.

PedalBox can also be used alongside a compatible DTUK engine tuning box because the two products perform different jobs: the tuning box changes engine performance, while PedalBox changes accelerator response.

Mercedes EQ & Electric Models – PedalBox EV

Mercedes-Benz has developed a substantial range of fully electric vehicles, including models within the EQA, EQB, EQE, EQS and other electric ranges.

A pure electric Mercedes does not use a conventional DTUK engine tuning box because there is no combustion engine, turbocharger or fuel system for that type of tuning system to control.

Compatible electric Mercedes models can instead use PedalBox EV, which has been developed specifically to change accelerator response on electric vehicles.

PedalBox EV does not increase the electric motors’ maximum power or torque. It changes the relationship between accelerator-pedal movement and the response requested from the vehicle.

Because of the way the current DTUK website product system is structured, an electric Mercedes may display PedalBox Pro as the selectable product. For a compatible pure-electric application, the product supplied is PedalBox EV.

Mercedes Tuning Box vs Remap

A common question from Mercedes owners is whether to use a tuning box or have the vehicle’s ECU remapped.

The two approaches are different.

A conventional remap changes software within the vehicle’s ECU. A DTUK tuning box is an external system that works with relevant engine-sensor signals without rewriting the original ECU calibration.

Neither approach should be described as universally better for every Mercedes.

The right choice depends on the vehicle, engine-management system, level of modification required and what the owner wants from the car.

This distinction has become increasingly relevant on newer vehicles as manufacturers have introduced different ECU architectures, security systems and methods of protecting engine-management software.

Why Choose DTUK for Your Mercedes?

DTUK has specialised in plug & play vehicle performance products since 2005.

Rather than using one universal product across unrelated vehicles, DTUK applications are matched to the specific engine and vehicle configuration.

Depending on the application, the DTUK Mercedes range can include:

• Plug & play diesel tuning systems
• Plug & play petrol tuning systems
• Selected hybrid tuning applications
• PedalBox accelerator-response controllers
• PedalBox Pro
• PedalBox EV for compatible electric Mercedes models

Products use vehicle-specific connectors and installation information is available for supported applications.

The products and performance figures shown on the individual vehicle pages are specific to that DTUK application rather than being based on one generic gain applied across the entire Mercedes range.

Does a DTUK Tuning Box Rewrite the Mercedes ECU?

No. A DTUK tuning box is an external tuning system and does not flash or rewrite the Mercedes vehicle’s original ECU software.

The system works with the relevant engine-sensor signals on the compatible application while the original ECU remains part of the vehicle’s normal engine-management system.

The DTUK system can also be removed, allowing the vehicle to operate without the external tuning box fitted.

This is one of the fundamental differences between a plug & play tuning box and an ECU remap.

Can I Fit a Mercedes Tuning Box Myself?

Many DTUK systems are designed for plug & play installation using vehicle-specific connectors.

The exact installation process varies between Mercedes engines because engine layouts and sensor positions differ between models and generations.

Rather than assuming every Mercedes takes the same amount of time or uses the same connections, check the fitting information supplied for your particular application.

If you are unsure about installation or identifying the correct Mercedes engine, contact DTUK before ordering and we can help confirm the appropriate application.

Find the Correct DTUK Product for Your Mercedes-Benz

Mercedes-Benz has produced a very large number of model generations, engine variants and power outputs, so selecting the exact vehicle is important.

Use the Mercedes vehicle selector below to choose your model, year and engine.

The individual application page will show the DTUK products currently available for that vehicle together with the relevant standard and expected tuned performance figures where engine tuning is supported.

If your Mercedes is fully electric, look for the compatible PedalBox option; where applicable, the EV-specific product supplied is PedalBox EV.

If you need help identifying your Mercedes or choosing between a tuning box and PedalBox, contact DTUK and we’ll help you find the correct application.

Once the system is installed you will immediately feel the increased power and torque that your engine has to offer, alongside improved throttle response and optimised driveability taking your Mercedes-benz to a whole new level of performance.

By transforming the torque and power on offer throughout the rev range you will find that your vehicle can more easily attain and maintain speed whilst also being able to drive smoothly in higher gears earlier and for longer helping you to increase economy. Many competitors look purely for the maximum power but that is rarely the optimal way to tune a vehicle. At DTUK we aim to ensure a vehicles drivability is maintained or enhanced so that power feels strong, linear and ‘factory’ in the way it is delivered.

We love to hear from our customers so if you have any pre-purchase questions please don’t hesitate to contact us.
