Engine Control Unit (ECU) with MS3X Expansion

The Diy autotune MS3X357-C is a powerful and flexible engine management solution designed for serious racers and custom builds. It offers advanced features that surpass earlier MS1 and MS2 systems, providing precise control over critical engine functions. This ECU boasts capabilities such as sequential fuel and spark, boost control, 2-step launch, progressive nitrous, and onboard traction control. It features 8 sequential fuel injector outputs, each capable of driving high impedance injectors, and 8 logic-level ignition outputs that support smart coils like IGN1A and LSx coils. Additionally, it includes 6 medium current outputs ideal for fan control or boost solenoids, 3 analog sensor inputs for external sensors like MAP or O2, 4 switch inputs for functions like launch control, and 1 cam sync input compatible with various sensor types. The MS3X also offers advanced tuning resolution with 16x16 VE and ignition tables and high accuracy for fuel and ignition steps. Data logging is supported via a built-in USB port and an SD card socket (SD card sold separately). Idle and mixture control, including closed-loop AFR control, are also included. Note: This ECU requires external ignition drivers or smart coils. An SD card and wiring harness are sold separately and must be acquired to complete the installation.
