Audi R8 V10 Software Upgrade
APR World Class Calibration Expertise With precise, professional installation by 2Bennett Audimotive
The 5.2L engine uses a Bosch MED 17 ECU for engine management. Basically, it’s a computer that tells the engine how to operate. Tuning software, like the APR ECU Upgrade, tells the engine how to make more power. It does this by optimizing the cam shaft positions, adjusting the air/fuel ratio, advancing ignition timing, throttle, intake and exhaust flaps, port/DI splits, thermal management and more.

Product Full Info
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.
Please note, our E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor.
