MSPNP2 Plug-and-Play ECU for Nissan KA24

Enhance your 1989-1994 Nissan S13, B13, P10, U13, or D21 with the AMP|EFI MSPNP2 Gen 2 Plug & Play ECU. Compatibility extends to a range of Nissan and Infiniti models, including the 1989-1994 USDM S13 240SX (KA24E/KA24DE), 1991-1994 B13 Sentra/NX (GA16DE/SR20DE), 1991-1993 USDM P10 G20 (SR20DE), 1990-1995 USDM D21 Hardbody Pickup (KA24E), and 1993-1994 USDM U13 Altima (KA24DE), all with manual transmissions. Key features include a no-wiring-required basic functionality, an average installation time under one hour, and a pre-loaded KA24 start-up map. It supports real-time tuning and data logging via laptop, as well as most aftermarket wideband sensors for accurate tuning. The ECU offers 16x16 fuel tables and 12x12 ignition tables for high-resolution tuning, multiple acceleration enrichment strategies, and closed-loop idle speed control. Advanced capabilities include support for up to 4 sequential fuel injector channels (requiring a specific Nissan Optical Trigger Wheel), onboard high impedance injector drivers, and the ability to remove the stock airflow meter. Additional features comprise 12x12 air-fuel ratio target tables, a built-in 2-step rev limiter with launch control, real-time barometric correction, an internal 4-bar MAP sensor supporting up to 44 PSI boost, overboost protection, closed-loop boost control, table switching input for instant map changes, flex fuel sensor input, and a CANBus connector for expanded integration. Important compatibility notes: This unit is strictly for Manual Transmission Only and does not support Automatic Transmission Control. It is also recommended to install a GM IAT sensor on models lacking a factory sensor for proper air temperature correction. Some classic MegaSquirt mods may not be compatible, such as certain transmission control units or VR sensors for cam/tach inputs.
