APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 5.0 TFSI V10. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.
The ECU’s MED 9 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.
APR's Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases turbocharger boost pressure and optimizes ignition timing, cam timing, lambda and more to produce higher output. To improve shift quality, boost pressure is lower in first gear. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to help ensure an enjoyable driving experience.
APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world!
Not only does our Stage I ECU Upgrade give you higher peak numbers of 741 horsepower and 779 ft-lbs of torque, but also gains of up to 237 horsepower and 299lb-ft are available at lower RPM's with 104 RON!
APR’s Electrical Engineers have the ability to alter the code structure of the ECU. Through code levels changes, APR's Engineers are able to add features to the ECU. Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners. This allows APR's engineers to often not require transmission software to meet or exceed advertised gains. On the highly modified end, this often allows APR to make turbo upgrades operate without the need for external manual controllers.
