APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 5.2L FSI V10 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. Optional features, such as APR's EMCS Program Switching and APR Mobile are available. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!
APR’s ECU Upgrades support various octanes. Each upgrade is fully compatible with an upgraded intake filter, catback exhaust, or other minor bolt on modifications.
Each stage includes optimizations to the power and torque gauges to match the increased output. All modes performance modes have the speed limiter removed and left foot braking enabled. We've raised the rev-limiter to 9,000 RPM in manual mode (or with a TCU Upgrade), and adjusted the thermal management system to optimize engine temperature. The throttle, intake, and exhaust flaps were optimized for power delivery. Furthermore we've completely optimized lambda control, port / DI split, cam phasing, ignition timing, and more to increase power. Lastly, we've added an optional quite cold-start mode that's an excellent addition for cars equipped with a loud exhaust.
The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 634-653 HP with 420-427 FT-LBS of torque, depending on octane. Gains as high as 86-104 HP and 53-64 FT-LBS of torque are available throughout the power band. To get more power, the vehicle can be outfitted with upgraded intake filters, catback exhaust and other small modifications without requiring any new modification to the ECU.
APR Stage 1 is available for 91 AKI, 93 AKI, and E85 fuel grades in North America, and 95 RON, 98 RON, and E85 fuel grades in the Rest of the World.
