Motiv Reflex + Control Unit

The ReFlex+ Control Unit is an advanced integration module for performance vehicle tuning and auxiliary component control. The ReFlex+ was designed to run in a variety of configurations from standalone tuning to full CAN Bus integration, the ReFlex+ offers unparalleled precision, flexibility, and performance.

Advanced Control Strategies

• Standalone Mode – No CAN Bus communication required
• Integrated CAN Bus – Compatible with MHD, EcuTek, MG Flasher, BM3 and any other tuning platform with the ability to receive and/or send CAN Bus messages.
• Advanced CAN Bus – Full integration with EcuTek and MHD+

Precision Sequential Port Injection & More

Originally developed to modernize port fuel injection, the ReFlex+ goes beyond traditional batch-fire controllers by delivering true sequential fuel injection. This ensures fuel is injected at the optimal moment for maximum efficiency, power, and reliability. But it doesn’t stop there—the ReFlex+ is a complete IO control hub designed for performance-driven applications.

Versatile Inputs & Outputs

With multiple patented technologies, the ReFlex+ is more than just an auxiliary injector controller. It offers advanced features typically found in high-end ECUs—at a fraction of the price. The ReFlex+ is equipped with a range of inputs and outputs to support flex fuel tuning, boost control, sensor monitoring, and more. 

Inputs:

• Sequential Port Injection – Supports up to 8 injectors with fault-sensing feedback
• 4x Analog Inputs – Compatible with 0-5V and 4-20mA sensors
• 2x Frequency Inputs – Accepts signals up to 10kHz and 20kHz
• Dedicated Flex Fuel Input – Reads ethanol content for real-time flex fuel tuning
• MAP, Cam, and Crank Sensor Inputs – Essential for engine timing and load calculations

Outputs:

• 4x Low-Side Auxiliary Outputs – PWM or digital ground triggers for methanol injection, nitrous, boost control, fuel pumps, and more
• 12V Switched Outputs – Power additional components with multiple ignition-switched voltage outputs

OEM-Level Integration & Flash Tuning Compatibility

The ReFlex+ seamlessly integrates with leading flash tuning platforms, including MHD, MG Flasher, and EcuTek, allowing the factory ECU to directly control ReFlex+ functions with built-in safety measures.

Fully programmable through TunerPro RT, the ReFlex+ supports universal and vehicle-specific configurations. Free starter maps and setup guides are available on our website, with additional support available through support@motivmotorsport.com.

Unlock the Full Potential of Your Build

Whether you're looking for precise auxiliary fuel control, advanced sensor monitoring, or the ability to control performance aftermarket components, the ReFlex+ delivers unmatched versatility.
