This document is an introduction to the Wideband Fuel Mixture Display (FMD). We modified the original Silicon Chip Fuel Mixture Display (that used a narrowband sensor) for use as a display for the DIY-WB wideband oxygen sensor controller. After first publishing how to modify the Jaycar KC-5300, we got Jaycar to make up the kits for us and we called them the TE-5300 display. These units were quite successful but we wanted them to be easier to build, so we created the improved TE-5301 display.
