APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.6L FSI VR6. 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. APR’s EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU.
The ECU’s MED 17 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, lambda and more to produce higher output!
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
The APR Stage I ECU Upgrade gives you higher peak numbers of 287 HP/274 FT-LBS on 93 (R+M)/2 octane and up to 294 HP/276 FT-LBS on 100 (R+M)/2 octane race fuel. As much as 14 HP and 24 FT-LBS of torque are available through the power band.
