APR Audi R8 5.2L FSI V10 ECU Upgrade

Automobile Magazine Review of APR Software

engineAPR is pleased to present the ultimate engine control unit (ECU) upgrade for the 5.2 FSI 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 on early models and through APR's CCD on newer models.

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 optimizes ignition timing, cam timing, throttle angle, lambda and more to produce higher output that goes beyond that of the higher output Lambororghini models.

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

Stage I ECU Upgrade

Not only does our Stage I ECU Upgrade give you higher peak numbers of 583 horsepower and 431lb-ft. of torque, but also gains of up to 53 FT-LBS of torque is available at lower rpms on the base R8 V10 model!
