The Motiv ReFlex+ is the controller that runs your port injection and flex fuel on Gen 1 B58 and other BMW inline-6 builds. It drives the port injectors sequentially, reads your ethanol sensor in real time and works alongside the factory DME – so you can run E85 and big power on a stock-location fuel system.
