APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.8T EA888 Gen 3 engine found in the B8.5 Audi A4 and A5. 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 Stage I ECU Upgrade
APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for the new 1.8T 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 288 ft-lbs of torque and 243 horsepower with 98 RON fuel. Large gains were seen throughout the power band, including an additional 70 ft-lbs of torque and 66 horsepower over the 177 PS model, and even higher figures over the lower output 140 PS models.
