I've talked to a couple people who had said that they would run Hondata and an FMU together. Doesn't make a lot of sense to me but then again I don't know. My plan was to run a walbro 255lph (high pressure or not?) fuel pump with 550 injectors with the aem fuel rail, filter, and pressure regulator and it was my understanding that the hondata s200b would control the fuel pressure from there based on boost. Am I wrong? probably making myself look like a dumb ass but I'm trying to figure this out.
