MOTIV ReFlex+ Advanced I/O Integration Kit – BMW B58 / S58 Plug-n-Play (Visconti Harness) – BMW F / G-Series & Toyota GR Supra

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 BMW B58/S58 plug-n-play kit: the ReFlex+ control unit and Inline-6 injector harness paired with the Visconti Tuning plug-n-play install harness, so there is no splicing into the engine harness. Visconti was the first company to offer a plug-and-play ReFlex+ harness and has refined it over years of use on some of the fastest Supras and BMWs. Standalone setups include a charge-pipe harness for boost reference; full CAN Bus setups do not need it. With port injection added, the kit lets the ECU run true flex fuel, scaling fuel volume to ethanol content without manual tune changes between blends, and supports fuel-pressure compensation of injector pulse width with fail-safes set in EcuTek RaceROM or MHD+.

TECH RESOURCES

Additional Parts Required

• A port injection rail kit, plate or aftermarket intake manifold with injectors — required, not included.
• Fuel lines and fuel line adapters — not included.
• A data-capable Micro USB cable (not a charge-only cable) is needed to configure, flash and datalog the unit — not included.
• Fuel pressure monitoring: MOTIV ReFlex+ 0-10 Bar Pressure Sensor (900.1024) (MOTIV-recommended accessory).
• Flex fuel: Continental Flex Fuel E85 Sensor (3/8" SAE) and MOTIV Plug-n-Play Ethanol Sensor Harness (200.1102 / 200.1119) (MOTIV-recommended accessories).
• Optional wireless monitoring: MOTIV ReFlex+ Link Control Unit (900.1042) with the Link Plug-n-Play Adapter Harness (200.1120).
• A supporting calibration on the factory ECU (MHD, EcuTek, MG Flasher or BM3) — not supplied by MOTIV.

Notes

• Which variant: select PT-CAN2 for all MHD+ and EcuTek cars with automatic transmissions; select PT-CAN for BM3 cars and all manual-transmission cars.
• B58 Gen 1 = F-Series M140i / M240i / 340i / 440i and G30 540i; B58 Gen 2 = G-Series M240i / M340i / M440i, Z4 M40i and GR Supra 3.0.
• Does not integrate with competing flex fuel kits; designed to replace Zeitronix / CANBOX Pro controllers in a Visconti flex fuel kit. Existing CAN Bus setups need an updated tune for hardware compatibility.
• Port injection alters the emissions configuration of the vehicle. Sold for competition use only; not legal for use on pollution-controlled vehicles where local law applies.
• Price is for the item selected only; labor is not included.
