APR Audi TT RS and RS3 2.5 TFSI ECU Upgrade
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 2.5 TFSI's engine management presented new challenges to the Engineering Teams at APR in the form of new control strategies. Significant time was spent researching these new strategies to properly request more load and therefore more boost in the lower end of the power band. The results were simple, a torque curve that crushes the competition and delivers a rush of power like no other in the industry.
APR’s 2.5 TFSI ECU Upgrade is an expertly recalibrated engine control strategy that primarily remaps the engine's operating parameters, within the factory ECU, 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. Available in octane-specific variations, APR’s calibrations allow you to take advantage of fuel quality available in your area. APR’s patented EMCS functionality puts the control of your engine’s operation at your fingertips and allows for additional features and options to be installed to your OEM ECU.
APR Stage I and Stage II ECU Upgrades
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!
By simply adding APR's RSC Turboback Exhaust, you can take advantage of additional headroom in the system. Coupled with APR's Stage II ECU Upgrade, a free upgrade for existing APR Stage I Customers, expect power figures to climb up to 431 horsepower and 441 ft-lbs of toque on 93 octane fuel.
APR’s ECU Upgrade is the best power per dollar modification for the 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.
- Available Fuel Grades: North American 91, 93 &100 octanes ((RON+MON)/2) and Rest of World 95, 98 and 104 octane (RON).
- Requirements: Stage I requires no hardware upgrades. Stage 2+ simply requires an APR Downpipe Exhaust.
Acceleration Enhancements:
Beyond power 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.
Speed 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 your fun!
Increased 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 your driving style and fuel quality, you may see better miles per gallon!
Motorsport 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 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. As is with all features APR adds to the ECU, this feature may be removed upon request.

How to use APR EMCS Programs and Features without APR Mobile
To Enable EMCS:
Turn the ignition and cruise control to the on position. Do not start the engine. Ensure Security Lockout or Anti-Theft is disabled.
To Unlock the ECU or Disable Anti-Theft :
"SPEED+" is used to enter a digit and "SPEED-" is used to register the digit. Enter the first digit of the security code by pressing "SPEED+" up the number of times corresponding to the first digit, then press "SPEED-" down to register the digit. Repeat this step for each digit in the user defined security code. The check engine light and EPC light will flash to indicate the ECU is unlocked or Anti-Theft is disabled.
To Cycle through APR Programs:
Hold "SET" on the cruise control stalk. The check engine light will blink in sets of one to four blinks to indicate programs one through four. Release "SET" during this sequence to select a program. The EPC light will flash one to four times to indicate the program selected. The vehicle may be started.
To use Fault Code Erase:
Hold "RESUME" on the cruise control stalk. The check engine light will begin to blink. Release "RESUME" when the check engine light is flashing in groups of one blink per second. Fault Codes will be cleared.
To use Security Lockout to Lock the ECU:
Hold "RESUME" on the cruise control stalk. The check engine light will blink in sets of one to three blinks indicating different features. Release "RESUME" when the check engine light is flashing in groups of three blinks per second. The EPC and CEL will blink to indicate the ECU is locked.
To Enable Anti-Theft:
Quickly press "SET, SET, RESUME, RESUME, SET, SET, RESUME and RESUME". The check engine light will begin blinking. The vehicle's throttle will no longer work until the user defined security code is entered.
The APR Development Difference
APR DirectPort Programming:
APR’s patented DirectPort Programming is available for early ROW 2.5 TFSI ECUs! 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.
APR 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. It’s capable of logging many variables at once with data rates as high as 100 samples per second. Synchronous data logging is available for fine-tuning.
APR 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. ECU Composer takes calibration to a new level on the 2.0T FSI with APR's Quick Flashing. APR’s Calibration Engineers can reflash the ECU only a minute later rather than waiting 10 to 20 minutes between each flash.
APR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU to add features not available from the factory. Through code levels changes, APR's Engineers are able to add features to the ECU. Other changes allow higher torque limit than those achievable through only modifying calibration data. On the highly modified end, this allows APR to make Stage III Turbo Upgrades operate as if intended by the OEM. For most, the advantage of this ability is the addition of APR’s patented EMCS Functions. EMCS puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to your ECU.
