Overview

It offers advanced features typically found in high-end ECUs, such as true sequential fuel injection for maximum efficiency, power, and reliability. The ReFlex+ functions as a complete I/O control hub, supporting configurations from standalone tuning to full CAN Bus integration.
Show original supplier description
Its patented technologies enable true sequential port fuel injection, ensuring optimal fuel delivery for enhanced efficiency, power, and reliability. This unit serves as a comprehensive I/O control hub, capable of operating in standalone mode without CAN Bus communication or with full integration into tuning platforms like MHD, EcuTek, MG Flasher, and BM3. The ReFlex+ is equipped with versatile inputs and outputs to support a range of performance applications. It features sequential port injection for up to 8 injectors with fault-sensing feedback, 4 analog inputs (0-5V and 4-20mA), 2 frequency inputs (up to 20kHz), and a dedicated flex fuel input. Additional inputs include MAP, Cam, and Crank sensors crucial for engine timing. Outputs include 4 low-side auxiliary outputs for PWM or digital ground triggers (methanol injection, nitrous, boost control, fuel pumps) and 12V switched outputs for powering additional components. A key consideration for installation is the CAN Bus selection: PT-CAN2 is recommended for MHD+ and EcuTek vehicles with automatic transmissions, while PT-CAN is suitable for BM3 and all manual transmission vehicles. The ReFlex+ seamlessly integrates with leading flash tuning platforms, allowing the factory ECU to directly control its functions, and includes built-in safety measures to protect your engine. It is fully configurable via TunerPro RT, with free starter maps and setup guides available.
