Golf R 2.0T Engine


rabbitAcceleration 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.

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 your 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 your driving style and fuel quality, you may see better miles per gallon!

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. As is with all features APR adds to the ECU, this feature may be removed upon request.

APR EMCS Programs and Features

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. There are no adaptation tricks or marketing gimmicks involved - EMCS is unlike anything else in the market. EMCS has the ability to rewrite the operating map data, giving each map new and specific calibration for increased performance. EMCS is available at any APR Stage.

Program SwitchingProgram Switching:
Program switching allows the user to cycle though up to four different engine calibrations and operating modes all without the need for external hardware.

StockStock Mode:
By selecting stock mode, the ECU calibration is reduced to factory load levels, limiting performance.

Valet ModeValet Mode:
APR's Valet Mode protects your vehicle from becoming an expensive toy for unauthorized individuals. By enabling Valet Mode, the vehicle's engine and top speed will be greatly limited.

security lockoutSecurity Lockout:
Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features will appear comple

y invisible until a user specified 2 to 4-digit security code is entered.

PerformanceAPR Performance Modes:
APR's octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a comple

y new calibration, altered specifically for the characteristics of the fuel quality selected. Currently available octanes are 91/93/100 (R+M)/2 in North America and 95/98/104 RON in the rest of the world. In some situations, APR supports higher 104 (R+M)/2 octane race fuels at Stage 3 power levels.

How to use APR EMCS Programs and Features without APR Mobile


To Enable EMCS:
Turn the ignition and cruise control on, but don’t start the engine.

To Unlock the ECU:
This is only necessary if Security Lockout is enabled.
Enter your security code to unlock the ECU. “SET” is used to enter a digit and “CANCEL” is used to register a digit. Enter each digit by clicking the “SET” button the number of times corresponding to the digit, then use “CANCEL” to register the digit. Do this for each digit and the CEL and EPC light will flash to indicate the ECU is unlocked. The ECU will remain unlocked unless you lock it again.

To Cycle through APR Programs:
Hold “SET” on the cruise control stalk. The CEL will blink in set of one to four blinks to indicate programs one through four. Release “SET” during this sequence to select a program. Turn off the ignition, turn it back on and wait for the CEL and EPC to stop blinking before starting the engine.

To use Security Lockout to Lock the ECU:
Hold “RESUME” and the CEL will blink in sets of one to three blinks to indicate features one through four. Release “RESUME” when the CEL is flashing in groups of three binks per second. The EPC and CEL will blink to indicate the ECU is locked.

The APR Development Difference

DirectPort ProgrammingAPR DirectPort Programming:
APR’s patented DirectPort Programming is now available! 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 comple

y eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time without a trace!

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. 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 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. 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 AssemblyAPR 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. On the highly modified end, this allows APR to make Stage III to operate as if intended by the OEM. For most 2.0T owners, 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.
