Overview

Specs Overview 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.

Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.

APR EMCS Program Switching

Program switching allows you to access additional program modes and features from your cruise control stalk or your smart device with APR Mobile. Depending on the ECU, available memory, and selected options, up to four program modes and all features, can be installed.

Stock Mode - Go back to the stock power levels.

- Go back to the stock power levels. Performance Modes - Switch between octanes and program modes.

- Switch between octanes and program modes. Valet Mode - Neuters the vehicle, giving the driver minimal output.

- Neuters the vehicle, giving the driver minimal output. Security Lockout - Password protects program switching.

- Password protects program switching. Anti-Theft - Password protects driving the vehicle.

- Password protects driving the vehicle. Fault Code Erase - Resets ECU fault codes and adaptation.

APR Mobile APR Mobile installs on smartphones, tables and other devices, and connects wirelessly to your ECU. The app can then be used to access features such as program switching, fault code reading and resetting, and high speed data logging.

Extreme Testing APR’s ECU Upgrade has been full tested for the better part of a year prior to a public release. This includes summer and winter weather testing on multiple continents, high and low altitude testing, extensive track testing at multiple road courses, extensive drag strip testing and extensive road and daily driving testing. APR’s test vehicles are full instrumented with multiple sensors, including pre and post intercooler temperature and pressure sensors, pre and post turbine temperature and backpressure sensors, pre and post catalyst temperature and pressure sensors, and multiple pressure sensors throughout the intake system. APR test vehicles have seen over 700 HP in various configurations, on the stock engine internals, and have set multiple world records, including 10.5 second stage 1 quarter mile passes, and 9 second stage 3 passes.
