Porsche Tech Talk
Driving Modes, Features, and Safety
Driving Modes - Each upgrade offers a host of improvements beyond power alone. Using Porsche’s Normal, Sport, and Sport Plus modes offers varying levels of output while retaining all of the unique characteristics present in each mode. Sport and Sport plus modes give you full power and torque. Normal mode give you modest increase over stock, but focuses on economy and comfort. We’ve optimized boost, fueling, ignition, cams, and more to achieve greater power and torque in all scenarios.
Features - In Sport Plus mode we’ve reduced turbo lag during reapplication of the throttle by building boost while off the throttle. We have linearized the pedal maps for a more predictable throttle response curve, which works exceptionally well on the track. We’ve enabled left foot braking, and brake boosting. The speed limiter has been removed. We’ve optimized the software to better handle larger wheels without excessive torque interventions. And finally we’ve inverted the start stop functionality so the vehicle starts with this feature disabled.
Safety - With many customers tracking their Porsche, safety is paramount in our calibration strategy. Through the use of extreme datalogging equipment and additional sensors, thermocouples, and transducers, our engineers were able to fully optimize the ECU for advanced safety routines. This includes implementing several routines not enabled from the factory. The entire thermal management system is optimized to reduce engine bay temperature, and reduce intake air temperature, while also implementing advanced protection routines to prevent oil temperature from achieving unsafe levels. The exhaust crackles disable when temperature thresholds are crossed, and are only enabled in sport mode. Next, we help protect the engine from LSPI by preventing the engine from being lugged out in tall gears. We also protect the turbo from damaging compressor surge, and add in turboshaft overspeed protection. We’ve enabled new temperature protection routines to prevent the engine, exhaust, and other components from overheating, and have implemented temperature management strategies that are fully mindful of the platform’s limited fueling capabilities. We’ve optimized the injection strategy to not only deliver a fatter torque curve and better spool, but to reduce the chances of knock, and torque dips. This is also achieved alongside per cylinder ignition advance and fuel trimming.
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.
APR Stage 1
The APR Stage 1 ECU Upgrade is the first step towards tuning your engine. It produces up to 654-754 HP and 627-701 FT-LBS of torque with gains as high as +92-162 HP and +93-161 FT-LBS of torque at the wheels.
APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI, and E60-E85 fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON, and E60-E85 in the Rest of the World.
APR Plus
APR Plus is our APR Stage 1 ECU Upgrade with our limited powertrain warranty and it’s the first step towards tuning your engine. It produces up to 654 HP and 627 FT-LBS of torque with gains as high as +92 HP and +93 FT-LBS of torque at the wheels. Please check our warranty manual to understand modifications supported by APR Plus.

Porsche Rear Engine Dyno Testing Notes - This engine is extremely sensitive to intake air temperature (IAT) due to the rear engine and rear cooling design. Power figures on a stationary dyno will vary wildly with limited airflow compared to real world conditions. As IAT increases the calibration will intentionally reduce power to protect the engine.

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!
