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.\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\u003eHorsepower - More horsepower throughout the whole rpm band\u003c\/li\u003e\n\u003cli\u003eTorque - More torque throughout the whole rpm band\u003c\/li\u003e\n\u003cli\u003eFuel Grades - Multiple octanes from which to choose\u003c\/li\u003e\n\u003cli\u003eAcceleration - Accelerate faster with more power and reduced throttle lag\u003c\/li\u003e\n\u003cli\u003eBrake Boosting - Left foot braking or brake boosting added\u003c\/li\u003e\n\u003cli\u003eSpeed Limiter - Go as fast as you want with the speed limiter out of the way\u003c\/li\u003e\n\u003cli\u003eEconomy - While cruising, or driving normally, your fuel economy may benefit from our optimized calibration\u003c\/li\u003e\n\u003cli\u003eFlash Counter - Flash counter does not increase with each flash\u003c\/li\u003e\n\u003cli\u003eDirect Port Programming - Clean and easy install through the OBD II port without removing the ECU\u003c\/li\u003e\n\u003cli\u003eFree Updates - Get free updates for life\u003c\/li\u003e\n\u003cli\u003eGuarantee - 30 day money back guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv class=\"widget html\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"widget-content\"\u003e\n\u003ch2 class=\"title\"\u003eAPR ECU Upgrade Stages\u003c\/h2\u003e\n\u003cp\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\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\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":45942367780924,"sku":"ECU-42L-FSI-RS4","price":493.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/5934\/4956\/files\/apr-ecu-box_d8d3c073-af02-443a-8f32-254f20296664.png?v=1785528583","url":"https:\/\/rpm-racing.com\/products\/apr-performance-ecu-software-4-2l-ea824-v8-rs4","provider":"Racing Precision Motorsports","version":"1.0","type":"link"}
