APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.0T EA888 Gen 3 engine as found in the North American MK7 Golf R and MK3 S3! 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 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 379 ft-lbs of torque and 354 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 98 ft-lbs of torque and 74 horsepower. Even higher figures were achieved using race fuel. For those looking for a more modest bump in horsepower and torque, lower output software is available. In both cases the increase in horsepower and torque directly translates to an exceptionally quicker vehicle. Read More
