APR’s ECU Upgrade Now Available for Facelifted Audi (C7.5) S6 and S7 4.0 TFSI!

Posted on September 8, 2015 – 10:00 am

Achtuning is pleased to present APR’s ultimate engine control unit (ECU) upgrade for the Audi (C7.5) S6 and S7 4.0 TFSI V8. APR’s ECU upgrade is available in octane-specific variations, including 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 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.

The ECU’s MED 17 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!

The APR Stage I ECU Upgrade gives you higher peak numbers of 574 HP/638 FT-LBS on 93 (R+M)/2 octane and up to 597 HP/668 FT-LBS on 100 (R+M)/2 octane race fuel! As much as 186 HP and 243 FT-LBS of torque are available through the power band! APR’s latest ECU Upgrade is fully loaded with APR’s EMCS Program Switching and is compatible with APR Mobile.

APR software for the Audi Q5 3.0T is here!

Posted on June 14, 2013 – 10:44 am

Achtuning is proud to announce the ultimate ECU Upgrade for the Audi Q5 TFSI V6 is now available through APR’s patented DirectPort Programming! Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicles 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’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.

The APR Stage I ECU Upgrade gives you higher peak numbers of 334 horsepower and 332-ft. of torque measured at all 4 wheels, but also gains of up to 101 all wheel horsepower and 86 lb-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 allowing for higher boost levels and more power. The gain in torque is felt immediately, but the results are present across the entire powerband. Expect gains of 132 all wheel horsepower over stock, a second dropped sprinting from 0-60 mph and over 7 seconds faster in a 62-124mph sprint! 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 octanes.
  • Requirements: Stage I requires no hardware upgrades. Stage 2+ simply requires an APR Supercharger Pulley Upgrade.

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.

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!

Left Foot Braking:
APR’s Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped Q5’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 Q5 the edge it needs at the track. As is with all features APR adds to the ECU, this feature may be removed upon request.

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 Q5! Any APR Dealer in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicles 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 3.0T 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 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.

Security, Warranty and Money Back Guarantee

All APR ECU Upgrades are fully encrypted to prevent theft of our valuable and proprietary coding information by lesser companies.

30 Day Money Back Guarantee:
All APR ECU Upgrades include a 30-day money back guarantee with no questions asked. If for any reason you are dissatisfied with the APR ECU Upgrade, return to your place of purchase for a full refund, provided you are within the 30 day period from the time of your initial purchase. Labor or shipping charges are not included in the guarantee and are at the discretion of the place of install.

Limited Lifetime Warranty:
All APR ECU Upgrades include a limited lifetime warranty against defects in the software, and to provide free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty and are at the discretion of the place of install.
