{"product_id":"plug-and-play-engine-management-system","title":"Plug and Play Engine Management System","description":"The DIYAutoTune MSPNP2-NJ8994 is a fully standalone, plug-and-play engine management solution designed for the 89-94 Nissan S13 SR20DET engine with a manual transmission. It offers a budget-friendly and capable alternative for motorsports applications. Installation is straightforward, with no wiring required for basic functionality, and an average install time of under 1.5 hours. The unit comes pre-loaded with an SR20DET start-up map to help your engine start on the first turn of the key.\n\nThis ECU features 16x16 fuel tables and 12x12 ignition tables for high-resolution tuning, along with multiple acceleration enrichment strategies and closed-loop idle speed control. It supports up to 4 sequential fuel injector channels (minor wiring change required for sequential injection) and can drive both high and low impedance injectors directly, eliminating the need for an external ballast resistor. The system allows for the removal of the stock airflow meter and includes 12x12 air-fuel ratio target tables for precise tuning with a wideband O2 sensor.\n\nAdvanced features include a built-in 2-step rev limiter with launch control and flat shift, real-time barometric correction, and an internal 4-bar MAP sensor capable of reading up to 44 PSI of boost, complete with overboost protection. It also offers closed-loop boost control (requires a boost solenoid kit), a knock sensor input with adjustable sensitivity and headphone output for tuning, table switching input for on-the-fly map changes, and a flex fuel sensor input for seamless switching between E85 and gasoline. A CANBus connector allows for expansion with other MegaSquirt-compatible devices.\n\nImportant installation notes include the requirement for an IAT sensor and a DIY 50mm Nissan Optical Trigger Wheel, both of which are included. Compatibility is limited to 1989-1994 JDM S13 Nissan Silvia and 180SX models with the SR20DET engine, as well as SR20DET engine swaps utilizing the factory S13 SR20DET harness, all with manual transmissions.","brand":"DIYAutoTune","offers":[{"title":"Default Title","offer_id":52687705014584,"sku":"MSPNP2-NJ8994","price":829.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664193285.webp?v=1784886367","url":"https:\/\/store.motormia.co\/products\/plug-and-play-engine-management-system","provider":"MOTORMIA","version":"1.0","type":"link"}
