APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.8T Turbo S engine!

APR’s ECU Upgrades are the best value modification one can make to the 3.8T 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, 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 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 fuelling 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 623-672 HP with 621-648 FT-LBS of torque, depending on octane. Gains as high as 92-110 HP and 99-116 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.

APR Stage 1 is available for 95 RON, 98 RON, 104 RON, and 108 RON.

APR Stage 1+ ECU Upgrade

The APR Stage 1+ ECU Upgrade is the next step towards making more power! This simple upgrade requires an upgraded intercooler system and no engine hardware modifications, and produces 642-685 HP with 623-650 FT-LBS of torque, depending on octane. Gains as high as 92-110 HP and 100-117 FT-LBS of torque are available throughout the power band. To get more power, the vehicle can be outfitted with an upgraded intake, or exhaust system.

APR Stage 1 is available for 95 RON, 98 RON, 104 RON, and 108 RON.

APR Calibration Report
StageFuel gradeMax HPMax TQMax HP Gain Over StockMax TQ Gain Over Stock
- APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.
- Max increases are based on APR's actual measured stock values and not those reported by VAG.
- Reported wheel figures measured on APR's in house Dynamometer using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications. On the dyno, this platform will see large swings in power based on intake air temperature, and the gear in which it's dynoed.
