{"product_id":"thundermax-ecm-for-magnetti-marelli","title":"ThunderMax ECM for Magnetti Marelli","description":"The ThunderMax 309-312 ECM is a performance-driven, award-winning module built exclusively for Magnetti Marelli–equipped EFI Harley-Davidson® motorcycles from model years 1995–1998. It brings modern tuning control and enhanced reliability to these early-generation EFI bikes.\n\nThis kit arrives fully assembled and includes wide-band Bosch 5-wire oxygen sensors (18mm), a plug-in harness, AutoTune module, USB communication cable, a speed harness, and a tip sensor.\n\nThe ThunderMax system utilizes proprietary AutoTune technology in a closed-loop control system to continuously adjust and perfect the air\/fuel ratio in real time. It features fueling points mapped every 1.5° of throttle and every 256 RPM, along with a built-in barometric sensor for automatic altitude and ambient air compensation. Riders can utilize pre-loaded basemaps or fine-tune AFR maps, ignition timing, startup fuel, idle speed, rev limits, and speedometer calibration via the downloadable ThunderMax software.\n\nThis product is intended for \"RACE READY\" vehicles only and is not legal for sale or use in the state of California or on any pollution-controlled vehicle. The ECM utilizes 18mm O₂ sensors, and if using a factory exhaust with 12mm ports, 18mm bungs will need to be welded in (bungs not included). The system comes with a 3-Year Factory Limited Warranty and is 100% engineered and made in the USA.","brand":"Thundermax","offers":[{"title":"Default Title","offer_id":52664169759032,"sku":"309-312","price":1088.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687545187.jpg?v=1784334595","url":"https:\/\/store.motormia.co\/products\/thundermax-ecm-for-magnetti-marelli","provider":"MOTORMIA","version":"1.0","type":"link"}
