Show original supplier description
The MegaSquirt MSPNPPro-JZ9298 is a Plug and Play (PnP) standalone engine management system built on MS3Pro technology. It is designed to completely replace the stock ECU and offers comprehensive control over your engine's spark and fuel delivery, enabling high-resolution tuning with 16x16 fuel and ignition tables. This system provides advanced features such as multiple acceleration enrichment strategies, closed-loop idle speed control, and air conditioner control. Key features include six sequential fuel injector channels with individual trim tables, supporting both high and low impedance injectors without the need for an external ballast resistor. It also allows for the removal of the stock airflow meter, enabling the use of Speed Density mode with the internal 4-bar MAP sensor, which can read up to 44 PSI of boost. For enhanced performance, it offers boost control for single turbo or sequential twin turbo systems, with adjustable parameters based on RPM, throttle, ground speed, or gear. Additional advanced features include 12x12 Air Fuel Ratio Target Tables for wideband O2 sensor tuning, multiple traction control strategies, a built-in 3-step rev limiter/launch control, real-time barometric correction, overboost protection, and closed-loop boost control (requiring a separate boost solenoid kit). The MSPNPPro-JZ9298 is compatible with: 1993-1998 Toyota Supra Turbo (manual transmission), 1993-1997 Toyota Supra non-turbo (manual transmission), and 1992-1997 Lexus SC300 (manual transmission). Installation is designed to be straightforward, with an average time of under 1 hour. The system includes 8 GB of internal data logging, supports most aftermarket wideband sensors, and features a CANBus connector for integration with other MegaSquirt-compatible devices like EGT input modules or additional sensors. The package includes the ECU, RS232 tuning cable, tuning software and documentation on a USB stick, vacuum hose and 'T' fitting, mounting screws, and a registered version of TunerStudio and MegaLog viewer.
