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 ECU Upgrade Stages

Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.

The result of this work is nothing short of astounding. Not only have we increase power, we’ve added many safety routines to ensure the engine and components are protected under demanding scenarios. Additionally we’ve added features to enhance the driving experience.

We’ve recalibrated the exhaust flaps to reduce backpressure and create consistent turbo spool characteristics. Sound characteristics are improved too, especially during free-rev, which sees its limiter raise in park and neutral. We’ve added an optional feature to enable exhaust crackle, which mimics much of the behavior of the RS models without being over-the-top and obnoxious. This enables during free-rev, downshifts, and lifting off the throttle. It’s optimized with exhaust flap actuation, and includes safety routines to ensure component protection. Through proper torque management and ECU code changes, we’ve removed the requirement of a transmission tune to achieve full torque. We’ve optimized launch control for a better take-off and enabled boost building on the line. Additionally we’ve defaulted the start-stop feature to the off position, removed the speed limiter, added left-foot braking or brake-boosting, and configured the ECU to send the correct calibration to the dash for the performance gauges.

To protect the engine and components we’ve spent a considerable amount of time tuning safety routines, some of which were not active from the factory. The ECU will protect the engine should the exhaust flaps fail as back pressure becomes too high. The optional exhaust crackle feature will turn off should components get too hot. The engine has advanced LSPI protection to prevent the engine from damage when being lugged in the tallest gears. Excessive intake air temperature, which is common on a dynamometer, will cause power to reduce to protect the engine. Furthermore more we’ve added and calibrated protection routines for turbocharger pressure ratios, shaft speed, exhaust pressure, intake air temperature, coolant temperature, oil temperature, lambda, fueling system limitations, and more.

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.

APR Stage 1 

The APR Stage 1 ECU Upgrade is the first step towards tuning your engine. It produces up to 384-435 HP and 499-557 FT-LBS of torque with gains as high as +86-144 HP and +137-214 FT-LBS of torque at the wheels. Torque limited files are available for vehicles with the DL382 Transmission and factory TCU software. This software limits torque to 520 Nm.

APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, and 104 AKI in North America and 95 RON, 98 RON, 104 RON, and 108 RON in the rest of the world.

The APR Difference

Who we are - We’re a global automotive engineering firm nestled in Opelika, Alabama. Our 80,000ft² state-of-the-art facility is home to some of the best engineers in the industry, who have mastered hundreds of engine management systems. We have multiple engine and chassis dynos, and the resources necessary to create our ECU Upgrades in-house, from the ground up! We're not a new company either. We've been around since the 90's and we have a strong financial backing to ensure we'll be here to support you for decades to come!

What we do - We optimize everything to make your engine more powerful. We adjust air-fuel ratios, advance ignition, increase boost pressure, alter cam positions and lift profiles, and more, all depending on the type of engine and management system, of course! We don’t take shortcuts, and we don’t take risks. We do it the right way.

How we differ - With our proprietary calibration and direct ram access data logging tools and operating system code changes, we’re able to make some of the strongest and fastest ECU upgrades, without needing costly end user adjustments. We work with the ECUs intelligent modeling and closed-loop systems, and beta test in multiple environments to create upgrades that work no matter where you drive!
