APR 2.5 TFSI EA855 EVO ECU Upgrade

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 Stage I ECU Upgrade

The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 459-542 HP with 451-506 FT-LBS of torque, depending on octane. Gains as high as 66-132 HP and 88-146 FT-LBS of torque are available throughout the power band. To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU. Upgrading the small factory intercooler is highly recommended on this platform.

APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI and E85 fuel grades in North America, and 95 RON, 98 RON, 102 RON, 104 RON, 108 RON and E85 fuel grades in the Rest of the World.

Please note, our E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels. To ensure proper E85 content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself and follow our switching guide. For maximum safety, especially on vehicles that see road course use, or long autobahn top speed runs, APR recommends NGK heat range 9 (NGK-R7437-9) spark plugs gapped to 0.024" ±0.002" or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km.
