NGP is pleased to present APR's ultimate ECU Upgrade for the Audi S8 4.0 TFSI V8!
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. 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.
Stage I ECU Upgrade
The APR Stage I ECU Upgrade gives you higher peak numbers of 647 HP/671 FT-LBS on 93 (R+M)/2 octane and up to 685 HP/679 FT-LBS on 100 (R+M)/2 octane race fuel. As much as +130 HP and +142 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.

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.
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 and to include protection to our clients by keeping the upgrade undetectable to a dealership's VAG diagnostic tool.
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. Installation may be additional and is not included in the warranty.
All APR ECU Upgrades offer a 30 day money back guarantee with no questions asked. If for any reason you are unhappy with your APR ECU Upgrade you may return the upgrade to your place of purchase for a full refund provided you are within a 30 day period from your time of initial purchase. Installation is not included in the guarantee and is at the discretion of the place of install.
APR Mobile
APR Mobile installs on smart phones, tablets and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU. Once connected, the device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions.
You will need to purchase an APR Mobile Bluetooth Dongle to connect your mobile device with your car. Please check out this post for more information on the APR Mobile App.
Please note: Vehicle must be present in order to complete the programming process. Please do not mail your ECU to us to be programmed!
