APR Audi 5.2L FSI Gen 2 ECU Upgrade

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 5.2L FSI V10!

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.

Ethanol (E85) Disclaimer
This APR ethanol (E85) calibration is not flex fuel. As a result, running the wrong fuel, on the wrong file, could cause the car to run poorly, especially during cold start, and could potentially be dangerous for the engine. By reading and accepting this, you understand that running the E85 software requires you have E85 in your fuel tank. If you intend to run 91 or 93 octane but have the E85 software installed you should visit your APR dealer, have them flash you to the 91 or 93 octane file, drain the tank of E85, and fill with 91 or 93 accordingly.

General Disclaimer
Enhancing the performance of a vehicle through hardware or software modifications sold by APR, LLC will increase the stresses and wear placed on the vehicle's engine, parts and components and drivetrain. This in turn may accelerate their normal wear and need for service and replacement and decrease their longevity. This is true even for versions of software that are lower output because such lower output versions create less stresses than the high output versions but still increase the stresses relative to factory settings. APR, LLC makes no claims, promises or guarantees regarding the effects any of its products have on the longevity of the engines, parts and components or drivetrains of customer vehicles.
The customer understands that installing APR, LLC products could void the manufacturer's or other third party warranty should any part or component covered by the warranty fail. The customer further understands and agrees that APR, LLC expressly disclaims and shall have no liability for any damages of any kind related to vehicle, engine, parts or components or drivetrain failures or a manufacturer or third party refusing to honor a warranty. In furtherance and not in limitation of the foregoing, APR, LLC EXPRESSLY DISCLAIMS ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS.
Access to APR, LLC software is expressly conditioned upon acceptance of all terms and conditions contained in this agreement.
