SpeedCircuit E-Tuning Update
SC_TUNE_UPT
Regular price $2.00 Save $-2.00Good for $1 towards a an e-tune update from SpeedCircuit.
If you have a previous e-tune from us, you can use this item to pay for additional tuning services, as needed. For example, if you had a previous tune with us and you changed your intake, it will require an update to your tune. Rather than starting from scratch, we can simply modify your existing tune.
To cover any dollar amount, simply change the quantity in your shopping cart.

Note: The tunes are the intellectual property of SpeedCircuit, and may not be shared with anyone without written consent. Furthermore, it is the responsibility of the owner to ensure that the car is mechanically sound. SpeedCircuit is not liable for any damages that may occur to your car. E-Tunes are done at your risk.
You may be asked to log more items as the tune progresses.
Please be sure to only do one full throttle pull per log. The pull should be from 3200-7000rpm unless specified otherwise.
Warning: E-Tuning requires that the driver of the car be aware of potential issues that may arise during tuning. This may include the car running lean, overboosting, detonating, or any other mechanical issues. If something doesn't feel right, take your foot off the throttle immediately and end the pull. SpeedCircuit, LLC is not responsible for any damages your car may incur! If you are not comfortable with this, please visit us for an in-person tune.
Expect one updated tune file per week until completion. This will vary based on both our schedule and how quickly you can provide logs for the most recent update to your tune.
If you're not familiar with how to set up your car or computer to log or flash tunes on your car, or you need help with diagnostics, please check the Phone Support option.

APR ECU Upgrade for 3.0T 991.2 Porsche 911
ECU-30T-9912
Regular price $2,093.00 Save $-2,093.00Driving Modes - 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. Optionally quiet mode is available, which keeps the exhaust valves closed in Normal mode, unless driving rapidly. Optionally a “Low Torque” file can be requested that limits torque similarly to normal mode, but retains sport mode like peak power levels. 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.
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 exhaust system. Optionally manual transmission customers can request a lower torque file to help promote longevity on the factory clutch. Sport mode will have similar peak power, but torque will be capped similar to normal mode.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.
The APR Stage 3 GTS ECU Upgrade is the next step towards making more power! This simple upgrade only requires factory Porsche Carrera GTS turbos and no other engine hardware modifications, and produces 520-615 HP with 524-594 FT-LBS of torque, depending on octane. Gains as high as 152-228 HP and 196-266 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. With additional cooling we measured 565-648 HP with 548-594 FT-LBS of torque with gains as high as 185-262 HP with 220-266 FT-LBS of torque are available throughout the power band. Optionally manual transmission customers can request a lower torque file to help promote longevity on the factory clutch. Sport mode will have similar peak power, but torque will be capped similar to normal mode.
APR Stage 3 GTS 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.
Please note, our E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself and follow our switching guide.
