MOTIV ReFlex+ Advanced I/O Integration Kit – Universal V8 (Flying Lead) – BMW M5 / M6 / M8 / 550i / 650i / 750i / 850i (N63 / S63)

OVERVIEW

The MOTIV ReFlex+ is an advanced integration module for performance vehicle tuning and auxiliary component control. Built on multiple patented technologies, it is far more than an auxiliary injector controller: it delivers true sequential port fuel injection rather than batch-fire control, and acts as a complete I/O hub with analog, frequency, flex-fuel, MAP, cam and crank inputs plus four low-side auxiliary outputs for methanol, nitrous, boost control or fuel-pump duty.

ReFlex+ runs standalone with no CAN Bus, integrates over CAN with MHD, EcuTek, MG Flasher and BM3, or fully integrates with EcuTek and MHD+ so the factory ECU can command ReFlex+ functions directly with built-in safety measures. Everything is configured in TunerPro RT over USB, and MOTIV publishes free universal and vehicle-specific starter maps.

This is the universal V8 kit: the ReFlex+ control unit, an eight-injector main harness and a flying-lead install harness you terminate to the vehicle yourself. MOTIV lists it as a direct fit for BMW V8 vehicles — M5, M6, M8, 550i, 650i, 750i and 850i — with universal generic fitment for other V8 engines.
