APR 2.5 TFSI EA855 EVO ECU UpgradeAPR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5T EA855 EVO (Gen 2) engine!
APR’s ECU Upgrades are the best pound-per-horsepower modification one can make to the 2.5T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Optional features, such as APR's EMCS Program Switching and APR Mobile are available. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!
APR ECU Upgrade Stages
APR’s ECU Upgrades are available in multiple stages, supporting various octanes both with or without any hardware modifications. Specific software is available for use with a high flow downpipe exhaust system and drop-in turbocharger upgrades are coming soon. Each stage is fully compatible with an upgraded intake, intercooler, catback exhaust, or other minor bolt on modifications.
Each stage includes optimizations to the factory boost gauge making it react more quickly and corrections to the power and torque gauges to match the increased output. Furthermore, we’ve added left foot braking, removed the speed limiter, raised the rev-limiter and added a motorsport limiter, adjusted the factory exhaust crackle to protect the catalyst, optimized cold start, retuned the exhaust flap actuation for the best performance and sound in multiple modes, optimized high altitude mappings, retuned the throttle for better response, and completely optimized the driving experience for street and track use making for a much more enjoyable driving experience!
