APR ECU Software Launch RPM Limiter Option

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 standstill. 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 Motorsport

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.

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 '90s 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!
