APR ECU Upgrade Stages

Our ECU Upgrades are available in multiple configurations. Installation of additional performance hardware, such as an intercooler or intake systems, may provide further performance improvements.

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.

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.

APR’s Motorsport Launch Limiter is an optional feature that eliminates turbo lag and provides a user adjustable launching RPM to aid in vehicle acceleration from a complete stand still. Simply hold the clutch and accelerator while the vehicle is stationary and the engine’s RPM will hold at a predefined limit while boost pressure builds using a “clean,” catalytic converter safe, strategy. With the vehicle stationary, handbrake applied and clutch disengaged, the driver can set the launch RPM by raising the engine’s RPM and pressing the brake pedal to set and save the desired launching RPM. With practice, this method can result in violent acceleration off the line! This feature is for manual transmissions only.

APR’s Motorsport No-Lift Shift is an optional feature that allows the driver to maximize acceleration by reducing power, boost and time lost during a gear change. With the vehicle above 20 km/h and the accelerator pedal held above 98%, during a gear change, the strategy activates. The throttle remains open and boost pressure is not vented, resulting in more power immediately after a shift. This is achieved using a “clean,” catalytic converter safe, strategy, while the ECU automatically sets the appropriate time necessary for a torque intervention, allowing proper syncro alignment. No end user adjustment is necessary. The driver simply focuses on shifting as fast as possible! This feature is for manual transmissions only.

APR Motorsport was established in 2007 to prove APR’s products in some of the most demanding environments the vehicle and engine will ever see. Through extensive research and development, APR’s Engineering Teams are able to deliver ECU Upgrades backed by brutally track testing! Shortly after APR Motorsport’s success in Grand-AM, APR’s tuning packages became available to professional motorsport teams around the globe. APR Motorsport’s calibrations and engine packages have seen countless podium finishes, including several 12 and 24-hour endurance races on both stock and highly modified engines.
