    • APR Porsche 982 718 S 9A2B4 2.5 turbo ECU tuning software providing up to 439 horsepower - Dynographs and features

      Yes APR is on a Porsche software tuning release spree. Among the Porsche 991.2 Carrera, 991.2 Turbo S, and 718 GTS tunes you can now add APR 718 S 9A2B4 ecu tune software for both the 982 Boxster S and Cayman S models.


      The 9A2B4 motor gets overshadowed by Porsche flat-6's but it is no slouch. APR can get you up to 439 horsepower and 421 lb-ft of torque on race gas which are gains of 85 horsepower and 108 lb-ft over stock respectively.

      As usual with APR you get all the data for various fuel grades in both crank dyno and wheel dyno format plus all the tune feature information below.

      APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5T S engine! APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 2.5T engine. 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 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 utilize a high flow race DP exhaust system as the factory system poses minimal restriction.

      Porsche Mode Switching

      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 Stage 1 ECU Upgrade

      The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 398-439 HP with 387-421 FT-LBS of torque, depending on octane. Gains as high as 59-85 HP and 76-108 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. APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, and 104 AKI fuel grades in North America, and 95 RON, 98 RON, 104 RON, and 108 RON in the Rest of the World.

      How to Buy

      Visit any APR Dealer in the world. They will flash the ECU via the OBDII port.

      NOTE

      At the initial launch we will have limited ECU Box Code support. If you have an ECU we haven't seen, we'll need the ECU sent in for extraction and software creation. For this trouble, we'll provide the tune to you at a deep discount. Please contact us!
