    • APR releases their Porsche 718 9A2B4 2.5 Cayman/Boxster GTS ECU software tune with mode switching - 431 rwhp

      APR is absolutely crushing it on the Porsche front. They are quickly becoming the premier option on modern Porsche platforms and you can expect a spate of releases in quick succession. We are kicking things off with their 982 718 9A2B4 tune.


      Now, the power gains are very nice and you will notice APR is tuning for various fuels including 91, 93, 100, and 104+ octane race gas.

      The big news beyond the output and fuel ranges supported is APR taking advantage of Porsche's factory Normal, Sport, and Sport+ feature. That means right on the steering wheel you can change how aggressive you want the car with the aftermarket APR software. APR even posted dyno graphs for each mode on each fuel!

      Expect this feature to carry over to the 991.2 Carrera 3.0 models.

      Read about all the features, details, and output levels below.

      APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 2.5T GTS 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 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. 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.

      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!

        You guys aren't messing around. APR is about to become THE OPTION on the newer Porsche models. Taking advantage of the steering wheel modes is genius as well.

        Arin, is it possible to use the Sport and Sport+ modes for completely different maps? Can I have an E85 tune on Sport+ for example?
      1. Arin@APR's Avatar
        Arin@APR -
        Yes, that would be possible, but dangerous. On this platform there isn't enough fuel for E85 (well, unless you really turn down the power!). Also, we wouldn't want someone to switch from Normal 93 to Sport E85 with the wrong fuel. Future may see Program Switching to handle that via APR mobile or the cruise control stalk, which would make more sense.

        We have a fix for that, and it's been running pretty well!
        Do you guys want to test it out?

        What about a valet mode?

        I think he just means the 718 regarding E85 not the 911's.

        Yes, I'm aware of what he's talking about. We have a 718 in house as well, remember? Click here to enlarge

        No, we have a chargepipe port injection kit coming out soon. Pretty clean and easy install, uses stainless -4AN line with a couple billet pieces. No meth injection headaches.

        Very curious to hear more about this. Are you literally just injecting fuel into the charge pipe post TB?

        Yeah, I don't think we'll ever do anything like a single injector in the charge port.

        Yes, we're doing this on lots of platforms. s63tu, s55, 991.1/991.2 Turbo S, 718, B58, Kia Stinger, etc.

        No worries, I understand. Just in case you want to explore or test it out, the option is always open for you. Click here to enlarge

        Hybrid turbo Mk2 TTRS owner here that is interested in testing it out and a JB4 for the platform if that is a possibility. Feel free to DM if its an option as not to derail thread.
