You knew this was coming hot on the heels of the APR 718 software suite release. This is arguably the most impressive software release to date on the 991.2 9A2B6 3.0 platform and APR is providing considerable testing data along with being the first tuner to date so support OTS 100% E85 tuning.
This is a game changer namely in APR taking advantage of the ability for Sport Chrono equipped cars to change modes. Normal, Sport, and Sport+ all still work but each provides a different mode that alters the map. How that works and the data to go with it you can read about below.
E85 tuning is something tuners have struggled with but APR has it figured out and the numbers are outstanding. They are able to take a base 991.2 9A2B6 3.0 (Carrera, T) from 360 wheel horsepower stock to 474 wheel horsepower. The torque gain is almost 200 lb-ft at the wheels!
Read the full details below as this is a big deal for 991.2 3.0 enthusiasts with much more to come.

APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 3.0T engine! APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 3.0T 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.
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 454-501 HP with 439-523 FT-LBS of torque, depending on octane. Gains as high as 102-155 HP and 111-195 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 exhasut system. 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.

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!
