ECU with 8' Wiring Harness

The Microsquirt ECU with 8' Wiring Harness by MegaSquirt is an entry-level, fully assembled Engine Control Unit designed for versatile applications. It can operate as a standalone engine management system, a transmission controller, or a CAN I/O expansion module, making it suitable for power sports, single-cylinder engines, and up to 8-cylinder configurations. It offers 2 fuel outputs and 4 spark outputs, with support for over 40 ignition modes, including mainstream applications like GM LS1, Ford Zetec, Bosch Motronic, and Chrysler Gen III Hemis, as well as more unique modes like Renix Jeep and Suzuki Swift GTI. This ECU features a Freescale MC9S12 16-bit, 24 MHz processor and supports various fuel and spark table types, including speed density, alpha-N, and MAF-based systems. It boasts an injector pulse width resolution of 0.66 microseconds, allowing for precise fuel delivery. The hardware includes 2 saturated injector drivers (each capable of handling up to 4 hi-z injectors), 4 logic-level ignition outputs suitable for 4-cylinder Coil-on-Plug or 8-cylinder wasted spark configurations, and multiple general-purpose outputs for PWM idle control or other functions. It also supports a wide variety of OEM cam and crank position sensors, including VR, Hall effect, and optical inputs. Beyond engine management, the MicroSquirt offers capabilities for electronic automatic transmission control and can serve as an input/output expansion for MS3 ECUs. Its I/O expansion features include 7 analog inputs, 2 wheel speed inputs (VR or hall type), additional switch inputs, and multiple PWM/switch outputs. The unit is designed for a wide operating temperature range of -40 to +85 degrees C, ensuring reliability in various conditions. The package includes the assembled MicroSquirt ECU and an 8-foot wiring harness.
