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.
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 484-538 HP and 521-590 FT-LBS of torque with gains as high as +80-135 HP and +108-179 FT-LBS of torque at the wheels.
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!
