Microsquirt Plug & Play Engine Management System

The Stinger Performance Engineering Microsquirt Plug & Play system provides comprehensive engine management for Ford 2.3L engines, including turbo, supercharged, and naturally aspirated variants equipped with a TFI distributor. This entry-level ECU offers users full tuning control, making it a robust option for those seeking a "bare bones" tuning experience without the extensive features of higher-end models like the PiMPx/PiMPxs. The included 3-bar MAP sensor can manage boost pressures up to 29psi, and the system supports multiple load modes (speed density, alpha-N, MAF) with 16x16 fuel/spark tables. The package includes the Microsquirt EFI controller, a complete engine harness pre-configured for stock Ford sensors and the supplied IAT and MAP sensors, a 3-bar MAP sensor, an IAT sensor, MAP hose, a base tune, and a startup guide. It is designed to utilize high-impedance injectors; note that stock 2.3L turbo injectors are low impedance and will require replacement or an adapter. The ECU itself measures 4.7"x3.1"x1.67" and can be made waterproof. Key features include support for most OEM Crank/Cam/Position Sensors, batch fire ignition, 2 fuel outputs, 4 ignition outputs, 2 crank/cam inputs, PWM idle control, Flex Fuel support, RS232 serial communication, boost control capabilities (with an optional solenoid), on/off nitrous control, table switching, and a 2-step rev limiter/launch control. This system is compatible with a range of Ford 2.3L applications including the Mustang, Thunderbird, Merkur XR4Ti, Ranger, and custom swap applications. While the base price may seem lower than the PiMPx system, consider that the PiMPx can utilize stock low-impedance injectors and includes advanced features and support, potentially making it a more cost-effective solution depending on existing components and support needs. Installation requires a Windows-based laptop, a wideband O2 sensor controller, and high-impedance injectors.
