    • APR releases Porsche 991.2 9A2B6 3.0 tuning with full E85 software and mode switching for 2017-2019 Porsche 911 Carrera, C4, and T models

      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.

        Couple months now. It's a beast!

        Here's how we instrumented the car. Very safe!

        Looking forward to the track data to back it up. I'm also curious about the car only losing 25 - 30 hp through the driveline. This seems contrary to most tuners inflating this number and claiming huge crank output.

        So awesome.

        I couldn't decide if I want a 991.2 C2 or a 997 Turbo next. This APR release pretty much makes up my mind for the 991.2. I love all the functionality and safety built in, this is really impressive.

        Also I have a 991.1 and the interior is so much better than the 997 I don't think I could go back.

        Most tuners just throw out a percentage that over inflates the crank figures. I'm typically conservative with drivetrain loss, and do not use a percentage. If you would like to try your own percentage just to see how it looks, feel free to take our take a our published wheel figures, and add any percentage you'd like to come up with other figures at the crank.

        Lighter than GT2RS, getting close to its hp and comes with a manual, what's not to like? I just wish Syvecs got invovled and more development though. Still some road blocks ahead...I guess they don't want to invest as it will walk over the big brother.

        The car is underrated stock: https://www.porscheboost.com/content...d-dyno-results

        345 rwhp on a Mustang stock? On 91 octane? Wayyy underrated.

        I've asked Syvecs many times and they just say 'maybe'

        Would love to work with you but my GTS is at our house in Spain so probably not feasible. Will definitely get the package once released.

        @APR, what are the numbers like on a hybrid turbo car?

        Someone with hybrid turbos needs to get this flash from APR and post it up!

        600-620bhp max I would think. Otherwise, slipage will knock on your door, especially PDK guys.

        They will be working with a set of Tial M660's shortly. I expect a very solid and reliable tune as their test car is PDK.

        I don't have that answer yet, though Tyler is very interested in working on the Tial kit on his own car (Carrera T) and others.

        The way we calibrate may change that. We make sure torque reporting is accurate, so that gives the transmission the best opportunity to deliver the correct clamping pressure right off the bat. Next, we will profile the torque curve to be "safe" on the stock engine - that typically means we'll make sure we're not hammering on the engine with excessive low end torque. A nice flat curve may be in order! Finally, we hope to dive into PDK. We have a lot of good info on that front we're waiting to utilize. If we can get in there and remove the caps for clamping pressure, just like we do on other platforms, we'll greatly increase the capacity of the system, assuming the headroom is there.

        Time will tell.
