We're excited to announce APR's 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!
APR's new suite of software comes after months of extensive research and development that is typically absent from the aftermarket. This upgrade makes the engine more powerful and more exciting. APR has 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 APR's high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After exhausting of hours of testing and tuning, APR has 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.

Emissions:
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.
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.
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, cooling, exhaust, or other minor bolt on modifications.
The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 452-488 HP with 340-361 FT-LBS of torque, depending on octane. Gains as high as +58-94 WHP with +40-65 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.
APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI, and E60-E85 Ethanol fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON and E60-E85 Ethanol fuel grades in the Rest of the World.
