Product Details

This upgrade requires the vehicle to be dropped off at ECS Tuning's facility in Ohio and picked up the next business day.

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.0T EA839 engine!

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 3.0T 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. Once the ECU is unlocked, the software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

Each stage includes several adjustments and features to make the driving experience more enjoyable. We’ve not only made the engine more powerful, but we’ve improved acceleration, removed the speed limiter, enabled left-foot braking or brake boosting, defaulted the auto start/stop system to “off”, properly rescaled the boost gauge, optimized thermal management and protection, designed the software to support normal bolt on modifications while not requiring any for the baseline configuration, and eliminated the need for a TCU upgrade to deliver maximum torque while still accurately reporting torque to the ECU.

APR Stage I ECU Upgrade:

The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 431-480 HP with 467-549 FT-LBS of torque depending on fuel grade. Gains as high as 85-123 HP and 103-176 FT-LBS of torque are available throughout the power band, depending on fuel grade and factory output, making the vehicle exceptionally quicker in all scenarios.

APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI, and E60-E85 fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON, and E60-E85 in the Rest of the World.

Please note, APR's 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 or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor.
