APR is pleased to present the ultimate ECU Upgrade for the Audi S6 and S7 4.0 TFSI V8!
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 4.0 TFSI V8 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.
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. 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 ECU Upgrade
The APR Stage I ECU Upgrade gives you higher peak numbers of 560 HP/580 FT-LBS on 93 (R+M)/2 octane and up to 569 HP/605 FT-LBS on 100 (R+M)/2 octane race fuel. As much as 124 HP and 163 FT-LBS of torque are available through the power band! APR’s ECU Upgrade is the best power per dollar modification for the new 4.0 TFSI V8 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.
Acceleration Enhancements:
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the A6 and A7 through other calibrations changes. Artifical limiters are reduced resulting in a more responsive pedal without altering overall throttle sensitivity
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.
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!
Left Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped A6's and A7'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 A6 and A7 the edge it needs at the track. As is with all features APR adds to the ECU, this feature may be removed upon request.
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!
The APR Development Difference
APR DirectPort Programming:
APR’s patented DirectPort Programming is now available for the Simos 8.5 ECU as found in the Audi C7 A6 and A7! 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 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 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 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.
