Expect massive gains with up to 685-767 HP and 731-804 FT-LBS of torque on tap, depending on octane, from this simple software upgrade. APR's ECU Upgrades are the best dollar-per-horsepower modification one can make to improve engine performance. 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 ECU Upgrades are available with various features and supported octane levels and each stage is compatible with most typical bolt-on modifications. The software is installed to the vehicle's factory ECU through the OBD-II port resulting in a clean and headache-free install. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!\u003c\/div\u003e\n\u003cdiv class=\"full_description\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eDelivers up to 685-767 HP with 731-804 FT-LBS depending on octane\u003c\/li\u003e\n\u003cli\u003eMax gains of +229-324 AWHP and +265-343 AWFT-LBS depending on octane\u003c\/li\u003e\n\u003cli\u003eSupports 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\u003c\/li\u003e\n\u003cli\u003eOptional factory term limit matching limited powertrain warranty with APR Plus\u003c\/li\u003e\n\u003cli\u003eSpeed limiter removed\u003c\/li\u003e\n\u003cli\u003eStanding RPM soft limiter increased\u003c\/li\u003e\n\u003cli\u003eLeft-foot braking \/ brake boosting added\u003c\/li\u003e\n\u003cli\u003eProperly rescaled performance gauges\u003c\/li\u003e\n\u003cli\u003eOptimized thermal management and protection\u003c\/li\u003e\n\u003cli\u003eOptimized launch control strategy for faster response\u003c\/li\u003e\n\u003cli\u003eOptimized driveline protection during launch\u003c\/li\u003e\n\u003cli\u003eNo hardware required (Software only)\u003c\/li\u003e\n\u003cli\u003eSupports standard bolt on modifications\u003c\/li\u003e\n\u003cli\u003eEliminated the need for a TCU upgrade to achieve full torque\u003c\/li\u003e\n\u003cli\u003eFlash counter does not increase with each flash\u003c\/li\u003e\n\u003cli\u003eFree lifetime updates\u003c\/li\u003e\n\u003cli\u003eDirect OBDII port flash (No ECU removal)\u003c\/li\u003e\n\u003cli\u003e30 day money back guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eOur new suite of MG1 ECU 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 turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands 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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eOur ECU Upgrades are available in multiple configurations.

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: 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.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"HS Tuning","offers":[{"title":"Default Title","offer_id":45942375481404,"sku":"ECU-40T-EA825-9Y-GTS","price":1528.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5934\/4956\/files\/apr-ecu-box_5459abd9-f3af-470b-a0c9-233e05d202e7.png?v=1785528757","url":"https:\/\/rpm-racing.com\/products\/apr-performance-ecu-software-4-0t-ea825-v8-9y-cayenne-gts","provider":"Racing Precision Motorsports","version":"1.0","type":"link"}
