Looking for more power? APR now has engine upgrade options available.
These are true “flashes” of the engine computer (DME / ECU). These cover many of the Porsche’s, mostly the “forced induction cars”, like these: Porsche 911’s (996, 997, 991.2 and 992), Boxster (987 & 718/982), Cayman (987 & 718/982), Cayenne (2003 + Turbo), Macan (2015 +) engines! APR continues to expand the list all the time, so check often if you don’t see your car today.
APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the forced induction (read “turbo” based) engines. 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 software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install.
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 utilize a high flow race DP exhaust system as the factory system poses minimal restriction.
In Sport Plus mode APR has reduced turbo lag during reapplication of the throttle by building boost while off the throttle. APR has linearized the pedal maps for a more predictable throttle response curve, which works exceptionally well on the track. APR has enabled left foot braking, and brake boosting. The speed limiter has been removed. APR has optimized the software to better handle larger wheels without excessive torque interventions. And finally APR has inverted the start stop functionality so the vehicle starts with this feature disabled.
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. They’ve optimized boost, fueling, ignition, cams, and more to achieve greater power and torque in all scenarios.
Features
In Sport Plus mode they’ve reduced turbo lag during reapplication of the throttle by building boost while off the throttle. They have linearized the pedal maps for a more predictable throttle response curve, which works exceptionally well on the track. They’ve enabled left foot braking, and brake boosting. The speed limiter has been removed. They’ve optimized the software to better handle larger wheels without excessive torque interventions. And finally they’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 their calibration strategy. Through the use of extreme datalogging equipment and additional sensors, thermocouples, and transducers, their 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, they help protect the engine from LSPI by preventing the engine from being lugged out in tall gears. They also protect the turbo from damaging compressor surge, and add in turboshaft overspeed protection. They’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. They’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 Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, and 104 AKI fuel grades in North America
APR’s DirectPort Programming is now available! Any APR Dealer (Like us, BRracing) in the world, connected to the Internet, has direct access to APR’s latest ECU upgrades for loading directly over the vehicle’s OBD-II port. This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!
Here are sample dyno graphs for the corresponding vehicles that the tune’s were installed on:
California Smog Legal
Many of the APR software upgrades have been submitted to the California Air Resource Board (CARB) and have obtained an Executive Order (EO number), meaning the software tune is California Smog Legal (even the new smog laws enacted in July 2021).
