I bought a new wideband set up so I no longer need this one. Everything works perfect and it is ready to install all you need to do is plug in the add a fuse and ground and it is ready to go. Everything is included, even the original manuals. It doesn't have a round guage, it has a rectangular digital read out. It has only been used with unleaded fuel, both 100 octane and E-85. New it was $275, I am asking $150 obo. This includes the o2 sensor and all wiring done.
