{"product_id":"jackpot-2-ls-efi-system-1","title":"Jackpot 2 LS EFI System","description":"The Aces Fuel Injection Jackpot 2 LS EFI System is a standalone engine management system engineered for 1997-2014 GM Gen III and Gen IV LS-based engines utilizing 58x\/4x or 24x\/1x crank and cam trigger patterns. This system provides modern sequential fuel and spark control, dual wideband closed-loop learning, and the adaptability to support everything from stock street builds to high-performance applications. It is ideal for LS swaps or for upgrading factory ECUs, offering enhanced drivability and control.\n\nAt the core of the Jackpot 2 LS is Aces’ Gen 2 ECU platform, which significantly improves upon previous generations with 31x31 resolution tables compared to the Gen 1's 10x14 tables. This higher resolution provides more precise control over fuel and spark across a wider range of RPM and load conditions, leading to smoother engine operation and better drivability. The system also leverages dual wideband O₂ sensors for accurate closed-loop correction on both banks, compensating for potential bank-to-bank variances.\n\nThe Jackpot 2 LS system is designed for both ease of use and advanced tuning. An initial setup wizard, accessible via a handheld touchscreen or Bluetooth module, guides users through basic engine configuration. For stock to mild builds, the self-learning fueling strategy helps eliminate complex tuning. Experienced tuners can utilize the free Aces laptop software for full manual control and calibration refinement, making it suitable for aggressive camshafts, power adders, and race-focused combinations.\n\nThis system is compatible with common LS engines like LS1, LS2, LS3, LS6, LS7, LS9, and popular swap variants such as 4.8L, 5.3L, and 6.0L engines, provided they match the specified trigger patterns. It is crucial to confirm the crank and cam trigger pattern for accurate fitment.","brand":"Aces Fuel Injection","offers":[{"title":"Default Title","offer_id":52686752973112,"sku":"AS20261-MK-4016-2025B-500","price":2279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660178647.webp?v=1784876330","url":"https:\/\/store.motormia.co\/products\/jackpot-2-ls-efi-system-1","provider":"MOTORMIA","version":"1.0","type":"link"}
