It features a 16x16 VE and ignition table resolution with full interpolation, and boasts 0.1% fuel step resolution and 0.1° ignition accuracy. Connectivity is made easy with a built-in USB port for laptop access and an SD card socket for onboard datalogging.\n\nThis ECU is preconfigured for basic fuel and spark control using batch fire injection and a single logic-level ignition output. For more advanced applications, it can be expanded with the optional MS3X expansion card (sold separately). This upgrade unlocks support for up to 8 channels of sequential fuel injection and ignition control, enabling features like cylinder-by-cylinder fuel and spark trim, 2-stage progressive nitrous control, launch control, and table switching for dual fuel setups.\n\nKey core features include closed-loop fuel and idle control, GM stepper IAC support, CANBus communications, and native support for many OEM crank\/cam trigger patterns. The system is modular and offers an affordable path to advanced engine tuning for both basic and sequential race applications. Note that the MS3X expansion card, harnesses, and sensors are sold separately.","brand":"MegaSquirt","offers":[{"title":"Default Title","offer_id":52689021927736,"sku":"MS3357-C","price":659.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687366407.webp?v=1784900543","url":"https:\/\/store.motormia.co\/products\/3-ecu-v3-57-standalone-engine-management-system","provider":"MOTORMIA","version":"1.0","type":"link"}
