Description

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. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

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.

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!
