APR 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 dollar-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!
APR Plus ECU Upgrade with a Limited Powertrain Warranty
The APR Plus ECU Upgrade is the first step towards making more power, and it includes our limited powertrain warranty. This simple upgrade requies no engine hardware modifications, and produces 459 HP with 451 FT-LBS of torque. Gains as high as 66 HP and 88 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.
The APR Plus ECU Upgrade matches the performance of our Stage 1 ECU Upgrade (91 octane version). To get even more power, you can add any of our other Stage 1 compatible products and still be covered under the APR Plus warranty!
If you're not interested in the APR Plus limited powertrain warranty, and want even more power, check out our other Stages.
APR ECU Upgrade Optional Features
APR EMCS Programs and Features
APR’s Enhanced Modular Chipping System, (EMCS), brings selectable programs and features to the factory ECU, without the need to purchase external hardware switching devices. EMCS has the ability to completely rewrite the entire operating map data within the ECU, giving each program mode a completely different set of calibration changes. On this platform, this is contrary to the industry norm of capping limits, using multipliers, only swapping portions of a base calibration, or relying on knock activity to lower output. APR’s EMCS features and programs modes are activated via the factory OEM cruise control buttons, and optionally through APR Mobile. The vehicle’s cruise control will function normally while driving.
Program Switching:
Program switching allows the user to cycle through up to four different engine calibrations and operating modes all without the need for external hardware.
Stock Mode: By selecting stock mode, the ECU calibration is reset to the factory calibration.
Fault Code Erase:
Fault code erase allows the user to erase and reset engine related trouble codes and ECU adaptation data without using a specialty tool.
Security Lockout:
Security lockout prevents unauthorized individuals from using APR's EMCS functionality. When enabled, APR's EMCS features will appear completely invisible until a user specified 2 to 4-digit security code is entered.
APR Performance Modes:
APR's octane-specific calibrations are available for various premium and race fuels around the world. Each performance mode is a completely new calibration, altered specifically for the characteristics of the fuel quality selected.
Anti-Theft:
When activated, Anti-Theft prevents normal operation of the engine even if the factory key is used. The vehicle will be completely immobilized until a user specified 2 to 4-digit security code is entered.
APR Mobile
APR Mobile is a simple yet powerful tool designed to enhance the APR tuning experience.
APR Mobile installs on smart phones, tablets and other devices and provides a wireless connection to the vehicle’s engine control unit or ECU. Once connected, the device can be used to access APR’s EMCS program switching features, read and clear fault codes and data log the ECU at high data rates not found on other commercially available tools. The app can also be used to access APR’s latest news articles, locate dealers in APR’s network and review previously saved data logging sessions.
