Product Overview

APR ECU Upgrade for the Audi C7 S6/S7 4.0 TFSI V8

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 4.0 TFSI engine!

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 4.0T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

APR ECU Upgrade Stages

APR’s ECU Upgrades are available in multiple stages, supporting various octanes both with or without any hardware modifications. All stages are fully compatible with an upgraded intake, cooling system, catback exhaust, or other minor bolt on modifications. APR Stage II software is available for a high flow Race DP exhaust system and Stage III software is available for use with upgraded RS6 and RS7 turbos.

APR Stage II ECU Upgrade

The APR Stage II ECU Upgrade requires a high flow Race DP exhaust system and is available with 575-614 HP and 669-717 FT-LBS torque, depending on octane. Gains as high as +164-284 HP and +236-207 FT-LBS of torque are available throughout the power band! This software must be used with a high flow Race DP exhaust system.
