MOTIV ReFlex+ Advanced I/O Integration Kit – Universal Inline-4 (Flying Lead) – BMW N20 / N26 / B46 / B48 & Toyota GR Supra 2.0

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 Inline-4 kit: the ReFlex+ control unit, a four-injector main harness and a flying-lead install harness you terminate to the vehicle yourself. It suits any four-cylinder application, including BMW N20, N26, B46 and B48 engines and the Toyota GR Supra 2.0.
