Show original supplier description

It functions as a standalone port fuel injector controller and offers advanced I/O integration via CANbus. The unit features four auxiliary outputs and four auxiliary inputs, along with a built-in analog output specifically for N54 MHD Flex Fuel integration. Each ReFlex+ is fully configurable for any vehicle through programmable cam, crank, and map sensor inputs in tuning software. Users can select batch, semi-batch, or sequential fire modes for injectors. Additionally, the ReFlex+ can control other performance modifications like methanol injection kits, nitrous kits, boost control solenoids, fuel pumps, and relay triggers using its configurable outputs. It also includes inputs for monitoring data such as fuel pressure, exhaust gas back pressure, oil pressure, coolant pressure, and crankcase pressure, and can integrate this data into factory ECUs via CANbus for safety, data logging, or adaptive tuning. These harnesses do not void the ReFlex+ warranty and ensure a consistent, reliable installation. The harness kit includes all necessary components for a clean, hassle-free setup. This product supports S58/B58 engines and is intended for off-road use only. It is crucial to confirm fitment for your specific vehicle before ordering.
