MOTIV Re|Flex Advanced I/O Integration & Port Injection Controller

The Most Powerful, Flexible, and Expandable Standalone & Auxiliary Controller on the Market

The MOTIV Re|Flex is the industry-leading solution for advanced engine control, port injection management, and I/O integration, developed for enthusiasts and professionals demanding precise tuning, real-time data logging, and full control over aftermarket systems. Whether you need standalone sequential fuel injection, CANbus integration, or auxiliary output control, the Re|Flex does it all—in one powerful, compact unit.

🔧 What Is the Re|Flex?

The MOTIV Re|Flex is a fully programmable controller designed to:

• Run sequential port injection on engines with up to 8 cylinders

• Control auxiliary systems (methanol injection, nitrous, boost solenoids, fuel pumps, etc.)

• Log and integrate real-time sensor data

• Communicate with the factory DME/ECU via CANbus (optional but highly recommended)

Whether you're building a street-driven flex fuel setup or a high-boost race application, the Re|Flex is your all-in-one control module.
