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. The software is installed to the vehicle's factory ECU through the OBD-II port, resulting in a clean and headache-free install.

Features:

  • Torque - More torque throughout the whole rpm band
  • Program Switching - Change programs and access features with your cruise control stalk (Stage 1 Only)

Use NGK Iridium IX BKR9EIX spark plugs. To get more power, the vehicle can be outfitted with various other bolt-on modifications all without requiring any new modifications to the ECU.
