APR Audi TT RS / RS3 2.5 TFSI ECU Upgrade

engineAPR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5 TFSI. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU on early ROW models and through APR's CCD on newer models. APR’s EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU on select models.

The ECU’s MED 9 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR's Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases boost pressure, optimizes ignition timing, cam timing, lambda and more to produce higher output!

APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world

APR Stage I ECU Upgrade

engine

The APR Stage I ECU Upgrade gives you higher peak numbers of 410 horsepower and 447-ft. of torque, and gains of up to 76 horsepower and 95lb-ft are available throughout the power band!

rabbitAcceleration Enhancements:
Beyond horsepower and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.

vmaxSpeed Limiter:
APR’s ECU upgrade increases the vehicle's top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun.

ecoIncreased Fuel Economy:
APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved.

vmaxMotorsport Rev Limiter:
APR’s Motorsport Rev Limiter allows the engine to reach max RPM without the ECU slowing down acceleration several hundred RPM earlier. The result is more power to redline and a definable redline feeling as seen on Audi Quattro GMBH vehicles such as the RS4, RS5 and R8.

Left Foot BrakingLeft Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped vehicle's throttle input is disabled while pressing the accelerator and brake at the same time. Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track.

APR EMCS Programs and Features

APR’s EMCS, Enhanced Modular Chipping System, brings selectable programs and features to your factory ECU, all without the need to purchase external hardware. Others have attempted to imitate EMCS with 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.

To learn how to activate the programs and features, choose the vehicle's cruise control type from APR EMCS Owner's Manual.

APR Mobile

APR Mobile is a simple yet powerful tool designed to enhance the APR tuning experience.

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.

The APR Development Difference

DirectPort ProgrammingAPR DirectPort Programming:
APR’s DirectPort Programming is now available for early ROW models! Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicle's OBD-II port. This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!

APR ECU ExplorerAPR ECU Explorer:
APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system. Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates. These tools are also limited to a small, specific list of variables. APR’s ECU Explorer is capable of logging every variable found within the ECU with far more variables logged at once, at very high data rates.

APR ECU ComposerAPR ECU Composer:
APR’s proprietary ECU Composer is used for altering the engine management system. With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies.

APR ECU AssemblyAPR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR's Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR's engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this often allows APR to make turbo upgrades operate without the need for external manual controllers.
