After checkout, you will receive an email from USP Motorsports with instructions on how your ECU can be flashed. 

NOTE: This software must be purchased along with a required APR Software Flashing Cheetah Cable. (Note: We highly recommend getting the complete APR At Home ECU/TCU Flashing Kit to avoid any potential issues during the flashing process)

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, increased the stationary rev limiter, 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, 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 or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself and follow our switching guide.
