We're excited to announce our Engine Control Unit (ECU) Upgrades are now available for the Porsche 718 Cayman/Boxster (982) GTS 4.0L engine with the Bosch MG1 ECU! Expect exceptional gains from this naturally aspirated engine with up to 452-488 HP with 340-361 FT-LBS of torque on tap, depending on octane! Our new suite of software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We've extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After exhausting of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.

Features:

  • Delivers up to 452-488 HP with 340-361 FT-LBS of torque
  • Max gains of +58-94 WHP with +40-65 WFT-LBS of torque

This part is legal under the provisions of EPA’s Tampering Policy dated November 23rd, 2020. The company has reasonable basis (test results) to verify that this product allows the vehicle to operate within legal emissions standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and the EPA Tampering Policy. This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB. Once testing is complete with California, and an E.O. number is issued, this product will be updated to 50-state legal status.

Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number. Please Note: Being as this is a naturally aspirated engine, it's extremely sensitive to air density and temperature. This is most notable on a dyno where typical side cooling and airflow is not common and not representative of real world conditions. The vehicle will struggle to make power on the dyno without proper cooling, especially in less than ideal conditions. Porsche Motorsport suggests a 30C delta in ambient temperature corresponds to a loss of 35 HP, and each 5 HP will result in roughly .2 seconds a lap. Please Note: Each vehicle's year, make, and model may have multiple factory engine or transmission controller software part numbers, known as box codes, each with unique revisions. Manufacturers periodically release software updates that alter this information, which can only be determined by scanning the controller and is not publicly provided. Due to the variety of codes, some stages, octane levels, features, or options may not be available for specific codes. Therefore, our website provides a general guide based on general info such as Year, Make, and Model. Our system allows you to request unavailable software, and we offer a 30-day money-back guarantee if you're not satisfied.

    Driving Modes, Features, and Safety

    Driving Modes

    We’ve optimized fueling, ignition, cams, throttle angle, and more to achieve greater power and torque in all diving modes.


    Features

    The sport exhaust button now fully opens or closes the exhaust valves at the push of a button, without additional hardware or controllers. When closed, the flaps will open at wide open throttle when you’re above 4,500 RPM. We’ve raised the rev limiter to 8,300 RPM and increased the standing limiter in park and neutral to 6,500 RPM. Optionally we’ve enabled exhaust crackle found in other models while in park and neutral. We’ve corrected the factory HP and TQ values so the correct values are sent to the dash, though the dash will still cap the max amount without being reprogrammed. Lastly, we’ve removed the throttle body limiter for maximum power delivery.


    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. We’ve enabled new temperature protection routines to prevent the engine and cooling systems from overheating prematurely, which will be noticeable on the track. We’ve optimized the injection strategy to deliver a fatter torque curve and reduce the chances of knock, and torque dips. This is also achieved alongside per cylinder ignition advance and fuel trimming. Serious track enthusiasts should consider running race fuel, and adding additional coolant for maximum performance.
