Key Features:

• Complete self-tuning fuel injection system with automatic calibration
• XIM (Expansion Interface Module) for enhanced sensor inputs and control outputs
• TCU (Transmission Control Unit) for full electronic transmission control
• Compatible with GM LS Gen III and Gen IV engines (LS1, LS2, LS3, LS6, LS7, LSX, and more)
• Controls electronic 4L60E, 4L65E, 4L70E, 4L80E, and 4L85E transmissions
• Touch-screen handheld display for easy tuning and monitoring
• Pre-configured base maps for quick startup
• Wide-band oxygen sensor included for precise air/fuel ratio control

Ideal for street rods, muscle car restomods, off-road builds, and custom projects where you want modern LS performance with simplified installation. The self-learning capability means the system continuously optimizes fuel and timing parameters as you drive, eliminating the need for extensive dyno tuning or laptop programming.
