APR's ECU Upgrades are the best pound-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 optimisation 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.

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 optimised boost, fuelling, 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 linearised 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 optimised 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 optimise the ECU for advanced safety routines. This includes implementing several routines not enabled from the factory. The entire thermal management system is optimised 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 fuelling capabilities. We’ve optimised 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
APR’s ECU Upgrades support various octanes both with or without any hardware modifications. Each stage is fully compatible with an upgraded intake, intercooler, exhaust, or other minor bolt on modifications. Unlike many platforms, no "Stage 2" or additional software tweaks are required to properly utilise a high flow race DP exhaust system as the factory system poses minimal restriction.
APR Stage 1
This simple upgrade requires no engine hardware modifications, and produces 420-458 HP with 393-448 FT-LBS of torque, depending on octane. Gains as high as 42-81 HP and 52-106 FT-LBS of torque are available throughout the power band. To get more power, the vehicle can be outfitted with an upgraded intake, cooling, or exhaust system. No "Stage 2" software is required to use a high flow Race DP exhaust system.

Only use fuel equal to or higher than specified. Never use a lower octane fuel. 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.
