1.2 TSI / TFSI - APR ECU Upgrade

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 1.2 TSI / TFSI 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 Continental SIMOS 10.x 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 increases turbocharger boost pressure and optimizes ignition timing, lambda and more to produce higher output. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to help ensure an enjoyable driving experience.

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!

APR Stage I ECU Upgrade

The APR ECU upgrade is one of the best horsepower-per-dollar modifications for the 1.2T 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 168 ft-lbs of torque and 133 horsepower with 98 RON octane fuel. Large gains were seen throughout the power band, including an additional 37 ft-lbs of torque and 26 horsepower. Even higher figures were achieved using race fuel!
