Shop Install Only

Please note that your vehicle must be present in order to program your ECU. To schedule an appointment, please feel free to contact us.

APR is pleased to present the ultimate ECU Upgrade for the Audi TT RS and RS3 2.5 TFSI. After months of long nights and many hours of testing, development and more testing, we are pleased to offer you an ECU recalibration that is second to none. APR's extensive research and development provides you with a powerful ECU Upgrade with no loss of drivability or reliability. Expect tremendous increases in power and torque across the entire power band, improved throttle response and a smoother, more powerful top end.

The Audi 2.5 TFSI ECU Upgrade is an expertly recalibrated engine control strategy that remaps boost, timing, air fuel ratios and other engine management parameters to provide smooth and reliable power as if intended by the OEM. APR's ECU Upgrade is developed to work within the OEM and Tier 1 Supplier specifications for engine component stress tolerances and performance specifications. APR's ECU Upgrades are available in octane specific versions to allow you to take full advantage of the fuel quality available in your area.

APR's Motorsport Left Foot Braking feature is now available allowing customers more control over their vehicle's throttle. Under normal operation, throttle input is disabled while pressing the accelerator and brake at the same time, however this may be undesirable for those looking to get the most out of their vehicles performance on the track. Enabling the left foot braking feature, the driver will have complete control over the vehicle's throttle and braking system, which may give the edge he or she needs at the track.

Stage I ECU Upgrade

Not only does the APR Stage I ECU Upgrade give you higher peak numbers of 442 horsepower and 482 ft-lbs of torque, but gains of up to 73 horsepower and 79 lb-ft are also available at lower RPMs! APR's ECU Upgrade is the best power per dollar modification for the new 2.5 TFSI and gives it just the extra edge these cars lack from the factory without pushing the limits. With factory like smoothness and drivability APR's ECU Upgrade will fill the void in an otherwise excellent car.

EMCS Technology:

APR’s patented EMCS, Enhanced Modular Chipping System, brings selectable programs and features to your factory ECU, all without the need to purchase external hardware. Other companies have attempted to imitate EMCS with clumsy external switching devices that only replace or multiply portions of a “base” calibration. However, EMCS has the ability to completely rewrite the entire operating map data, giving each map a complete set of calibration changes. APR’s EMCS features and programs modes are activated via your OEM cruise control buttons. Your cruise control will continue to function as normal.

Possible programs include: stock, 91 octane, 93 octane, 100 octane and valet. Fault code erase, security lockout and anti theft features are available as well.

Installation is available at either of our shops. Please feel free to contact us to set up an appointment to have your car programmed.

APR Mobile

APR Mobile installs on smart phones, tablets and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU. Once connected, the device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions.

You will need to purchase an APR Mobile Bluetooth Dongle to connect your mobile device with your car.
