Designed for seamless integration with any Aces EFI system or as a standalone wideband system for carbureted engines and other aftermarket EFI setups.\u003c\/p\u003e\n\u003cp\u003eThe AFR (Air-Fuel Ratio) module is a device that measures how much air and fuel are mixed inside an engine during combustion. Engines run best when the mixture is balanced (not too rich with fuel and not too lean with air). By using a wideband oxygen sensor, the AFR module constantly reads exhaust gases and calculates the air-fuel ratio in real time. This data is then sent to the handheld through a CAN bus connection for datalogging and display.\u003c\/p\u003e\n\u003cp\u003eBuilt around the proven Bosch LSU 4.9 wideband oxygen sensor, this module delivers real-time, highly accurate air-fuel ratio (AFR) data directly to your handheld, giving you precise insight into your engine’s performance.\u003c\/p\u003e\n\u003cp\u003eThe Aces AFR Module also enables dual O₂ monitoring on TBI systems that typically use a single sensor, allowing your system to track both banks independently for optimized tuning. It’s equally valuable for carbureted applications where accurate AFR readings are essential for fine-tuning performance and fuel economy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailable in two configurations:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStandalone System: Includes either a handheld display or Bluetooth module for use with non-Aces systems.\u003c\/li\u003e\n\u003cli\u003eAces Add-On Module: Integrates directly with your existing Aces handheld for a streamlined expansion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTuning and performance:\u003c\/strong\u003e\u003cbr\u003eHelps ensure the engine is running at the optimal ratio for power or economy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiagnostics:\u003c\/strong\u003e\u003cbr\u003eQuickly shows if the engine is running too lean or rich, which prevents damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual-Channel Monitoring: \u003c\/strong\u003e\u003cbr\u003eTrack two independent AFR readings simultaneously for ultimate flexibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFast \u0026amp; Reliable: \u003c\/strong\u003e\u003cbr\u003eSensor warms up and delivers stable readings in under 20 seconds.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRugged Design: \u003c\/strong\u003e\u003cbr\u003eAutomotive-grade waterproof connectors, IP54-rated housing, vibration tested, and ready for extreme environments.\u003c\/p\u003e\n\u003cp\u003eFully compatible with all of Aces’ Fuel Injection and Ignition systems that support the Aces CAN network.\u003cbr\u003e\u003c\/p\u003e","brand":"Aces Fuel Injection","offers":[{"title":"Standalone","offer_id":47911669825641,"sku":"AS2040","price":499.99,"currency_code":"USD","in_stock":false},{"title":"Aces Add-on","offer_id":47911669858409,"sku":"AS2041","price":299.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0605\/1256\/7401\/files\/AS2040_Angle3.webp?v=1787013926","url":"https:\/\/www.dfwspeedsyndicate.com\/products\/afr-module","provider":"DFW Speed Syndicate ","version":"1.0","type":"link"}
