APR ECU Upgrade Stages

APR’s ECU Upgrades are available in multiple octanes levels. Each stage is fully compatible with an upgraded intake, catback exhaust, or other minor bolt on modifications.

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.

Dyno testing is a great way to gauge power increases over the entire rev range but may not translate to real world performance. Through GPS based acceleration testing, APR’s Engineers were able to verify increases made on the dyno translated to a faster and quicker vehicle on the street.

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.
• Performance Modes - Switch between octanes and program modes.
• Valet Mode - Neuters the vehicle, giving the driver minimal output.
• Security Lockout - Password protects program switching.
• Anti-Theft - 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.
