M&W Pro Drag 6 250mJ CDI (New S4 model, single box)

Unlike some multi-channel systems that require two units, the S4 model houses all six ignition channels in one compact box, simplifying installation and saving space.

This feature allows you to toggle between a lower energy setting (160mJ) for idle/cruise and high power (250mJ) for full-throttle racing to extend coil life.

It provides flexibility to match your ECU's specific requirements, allowing you to select between rising or falling edge triggers for precise timing synchronization.

While designed for drag racing, the switchable power levels make it more adaptable for limited street use compared to fixed high-output drag systems.

For optimal performance and to handle the 250mJ output, you must use coils specifically designed for high-energy CDI applications, not standard inductive coils.
