ReFlex+ Advanced I/O Integration | BMW N54

The ReFlex+ Advanced I/O Integration module is designed for BMW N54 owners who demand precise control over every aspect of their performance build. More than an auxiliary injector controller, the ReFlex+ delivers advanced features typically found in high-end standalone ECUs—at a fraction of the cost.

Whether running standalone tuning or fully integrated with CAN Bus platforms, the ReFlex+ gives you unmatched flexibility, precision, and reliability. It’s ideal for sequential port injection, flex fuel tuning, boost control, methanol injection, nitrous management, and other performance-driven applications.

Key Features:

• Standalone or CAN Bus Integration: Works with MHD, EcuTek, BM3, MG Flasher, or any tuning platform supporting CAN messages.
• Sequential Port Injection: True sequential fueling for up to 8 injectors, improving efficiency, power, and reliability over traditional batch-fire systems.
• Advanced Inputs & Outputs:
  • 4 analog inputs (0-5V, 4-20mA)
  • 2 frequency inputs (up to 20kHz)
  • Dedicated flex fuel sensor input for real-time ethanol monitoring
  • MAP, cam, and crank sensor support
  • 4 low-side auxiliary outputs for meth, nitrous, boost, or pumps
  • 12V switched outputs for additional components
• OEM-Level Integration: Fully compatible with factory ECU flash tuning, including MHD and EcuTek.
• TunerPro RT Configurable: Universal or vehicle-specific tuning options for precise control of all inputs and outputs.

Whether upgrading your N54 for track, street, or high-boost builds, the ReFlex+ puts complete control in your hands. Optimize fuel delivery, manage aftermarket performance components, and protect your engine with a fully configurable, professional-grade integration solution.
