engine

APR is pleased to present the ultimate ECU Upgrade for the Audi B8 and B8.5 S4 & S5 3.0 TFSI V6 available through the OBD-II Port via APR's Patented DirectPort Programming!

After months of long nights and many hours of testing, developing and more testing, we’re 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 faster acceleration, improved throttle response and more power across the entire power band.

APR’s 3.0 TFSI V6 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 and is thoroughly track tested through APR Motorsport's Grand-AM and World Challenge professional racing efforts. 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

engine

The APR Stage I ECU Upgrade gives you higher peak numbers of 362 horsepower and 345-ft. of torque measured at all 4 wheels, but also gains of up to 77 all wheel horsepower and 57lb-ft are available throughout the power band!

For those demanding more torque, The APR Supercharger Pulley Upgrade is the answer. Spinning the supercharger faster increases air flow and effectively doubles the low-end gains of Stage I. The gain in torque is felt immediately, but the results are present from beginning to end adding up to 80ft-lbs and 108 horsepower at all four wheels! Stage II+ Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.

APR’s ECU Upgrade is the best power per dollar modification for the new 3.0 TFSI V6 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 & 104 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 Supercharger Pulley Upgrade.

rabbitAcceleration Enhancements:
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the S4 and S5 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 S4 and S5’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 S4 and S5 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. 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.

Program SwitchingProgram Switching:
Program switching allows the user to cycle through 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 reset to the factory calibration. The engine will run exactly as it did before purchasing APR software.

PerformanceAPR Performance Modes:
APR's octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.

fault code eraseFault Code Erase:
Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a specialty tool.

security lockoutSecurity Lockout:
Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features will appear completely invisible until a user specified 2 to 4-digit security code is entered.

anti theftAnti-Theft:
When activated, Anti-Theft disables the starter even if the factory key is used. The vehicle will be immobilized until a user specified 2 to 4-digit security code is entered.

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 performance, engine RPM and top speed are all extremely limited.

How to use APR EMCS Programs and Features

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+" the number of times corresponding to the first digit, then use "SPEED-" 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 use Security Lockout to Lock the ECU:
Hold "RESUME" on the cruise control stalk. The check engine light will blink in set 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 cycle through APR Programs:
Hold "SET" on the cruise control stalk. The check engine light will blink in set 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 Enable Anti-Theft:
Quickly press "SET, SET, RESUME, RESUME, SET, SET, RESUME and RESUME". The check engine light will begin blinking. The vehicle will no longer start until the user defined security code is entered.

The APR Development Difference

DirectPort ProgrammingAPR DirectPort Programming:
APR’s patented DirectPort Programming is now available for the Simos 8.x ECU! 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 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 well over 100 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 3.0 TFSI 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. 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 or using piggyback devices as is the case for many tuners. This allows APR's engineers to not require DSG software to meet or exceed advertised gains. On the highly modified end, this allows APR to make Stage III Turbo Upgrades operate as if intended by the OEM. For most 3.0T 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.
