Performance tuning has traditionally meant scheduling a dealer or tuning-shop visit, but modern flash-tuning technology makes it possible to install software directly from home. The APR Ultralink brings APR's ECU and TCU tuning platform directly to the enthusiast, providing a convenient way to access supported engine and transmission calibrations through the vehicle's OBD-II port.

Designed for a wide range of Audi, Volkswagen, Porsche, Bentley, Lamborghini, SEAT, Škoda, and CUPRA applications, the APR Ultralink gives owners access to APR's software marketplace and allows compatible calibrations to be purchased, downloaded, installed, updated, or removed without requiring a dedicated tuning device for each vehicle.

At-Home APR ECU Tuning

The APR Ultralink is designed to make ECU flashing more accessible for enthusiasts who want to handle their vehicle's software installation themselves. After connecting the device to the vehicle's OBD-II port and a compatible computer, users can access available APR calibrations for their specific vehicle and controller.

Depending on the application, APR software can offer multiple performance stages, octane-specific calibrations, and additional adjustable features. The available options are determined by the vehicle's ECU, software revision, and supported APR calibration.

This application-specific approach is important because two vehicles with the same make, model, and model year may not necessarily have identical ECU software or available tuning options.

TCU Tuning Without a Dealer Visit

The Ultralink isn't limited to engine software. On supported applications, it can also be used to install APR TCU calibrations, giving enthusiasts the ability to upgrade their transmission software from home.

TCU tuning can provide application-specific changes to transmission behavior and available parameters, including supported torque limits and launch-control settings. The exact features depend on the transmission controller and APR calibration available for the vehicle.

For enthusiasts running upgraded engine software, a compatible TCU calibration can also provide a way to complement the vehicle's overall performance setup.

APR Ultralink Marketplace

At the center of the Ultralink experience is the APR Ultralink Marketplace, where users can access APR's catalog of supported engine and transmission software.

APR states that its platform includes more than 10,000 in-house-developed calibrations covering 140+ vehicle applications, with additional ECU and TCU support being added over time.

The marketplace allows users to identify software available for their vehicle and manage supported calibrations through the Ultralink system rather than relying on a separate physical tuning device for every application.

Multiple Vehicles, One Ultralink Device

One of the advantages of the APR Ultralink is that the hardware itself is not locked to a single vehicle.

The same Ultralink device can be used with multiple supported vehicles, while the actual software remains specific to the vehicle and controller being tuned. When connected to a supported application, the system identifies the relevant controller information and presents compatible APR software options.

This makes the Ultralink particularly useful for enthusiasts, households, or collections with multiple supported VAG-platform vehicles.

Flexible Software Features

Depending on the specific vehicle and calibration, APR software accessed through Ultralink can provide more than simply a performance tune.

Supported applications may offer features such as:

• Multiple performance stages
• Octane switching
• Adjustable launch control
• Torque-level adjustments
• Speed-limiter settings
• Exhaust sound settings
• ECU fault-code reading and clearing
• Flash-counter resets
• Software updates
• Return-to-stock functionality

Not every vehicle supports every feature. Available functions depend on the specific ECU or TCU, software revision, and APR calibration.

Octane Changes and Stage Updates

The Ultralink platform also makes managing compatible APR software more convenient. Where supported, users can switch between available octane calibrations without needing to purchase another Ultralink device.

Stage changes can similarly be managed through the APR platform when multiple calibrations are available for the vehicle. This gives owners greater flexibility when modifying their setup or adapting the vehicle's calibration to different fuel requirements.

APR also states that supported octane changes are available without additional charges.

Existing APR Customers Can Access Their Software

The Ultralink can also be useful for existing APR customers.

Customers who previously purchased qualifying APR software through an authorized APR dealer can have eligible software associated with their APR account for Ultralink access. This means purchasing an Ultralink does not necessarily require an existing customer to purchase the same qualifying software again.

This provides a straightforward path for transitioning from dealer-installed APR software to the Ultralink platform.

Easy OBD-II Connection and DIY Installation

The APR Ultralink is built around a straightforward OBD-II programming connection. The device connects to the vehicle's diagnostic port and communicates with the supported ECU or TCU through APR's software platform.

The system is intended for at-home use with a compatible Windows or macOS computer, allowing users to manage the flashing process without specialized workshop equipment.

Before installing software, it is important to confirm that the vehicle meets APR's application requirements and that the intended calibration is compatible with the vehicle's specific controller.

Check Your ECU or TCU Before Tuning

ECU and TCU compatibility is not determined solely by vehicle year, make, and model. Different software revisions and controller box codes can affect which APR calibrations are available.

For this reason, owners should verify their specific vehicle through APR's current application information before purchasing or installing software. Available stages, octane maps, transmission calibrations, and adjustable functions can vary between otherwise similar vehicles.

The APR Ultralink provides the hardware needed to access the platform, but software availability remains application-specific.

APR Ultralink Fitment

The APR Ultralink is designed for most APR-supported ECU and TCU applications across a broad range of VAG vehicles.

Supported brands include:

• Audi
• Volkswagen
• Porsche
• Bentley
• Lamborghini
• SEAT
• Škoda
• CUPRA

Application: APR-supported ECU and TCU applications
Connection: OBD-II
Systems: Engine ECU and Transmission TCU
Part Number: EM100040

Always verify the exact vehicle, ECU/TCU box code, and software revision with APR before purchasing software.

What's Included

The APR Ultralink package includes:

• APR Ultralink programming device
• Protective case
• APR Ultralink software access

With its compact design and OBD-II connection, the Ultralink provides a practical way to bring APR's supported ECU and TCU tuning capabilities directly to the enthusiast's garage.

For drivers looking for a more convenient way to manage APR software, the APR Ultralink combines at-home flashing, marketplace access, software updates, stage management, and supported ECU/TCU features into a single programming platform.
