APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0T EA888 Gen 3 engine. 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 Simos 18 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 Stage I ECU Upgrade

APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for the new 2.0T engine. The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 323 ft-lbs of torque and 302 horsepower with 98 RON fuel. Large gains were seen throughout the power band, including an additional 67 ft-lbs of torque and 74 horsepower. The APR Stage II ECU Upgrade is designed to work with a high flow downpipe which created new peak power and torque figures of 331 horsepower and 351 ft-lbs of torque. The additional hardware allowed the turbo to spool faster and power carried better towards redline, resulting in up to 104 ft-lbs of torque and 103 horsepower over stock!
