APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. 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 ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. On later ECUs the ECU needs to be unlocked with an APR CCD. After the unlock the software is installed to the vehicle's factory ECU through the OBD-II port, resulting in a clean and headache-free install.

Features:

  • Horsepower - More horsepower throughout the whole rpm band
  • Torque - More torque throughout the whole rpm band
  • Fuel Grades - Multiple octanes from which to choose
  • Acceleration - Accelerate faster with more power and reduced throttle lag
  • Brake Boosting - Left foot braking or brake boosting added
