air/fuel gauge.

purchased an aid for tuning, from dyna pro, lc-1, and xd-1 kit. looks to be a useful addition, kit can be used with lap top, to record fuel delivery in real time.the gauge itself is 19mm thick, gauge face can be customised. kit came with software, and a choice of bezels. check this link for picture. http://www.dynapro.co.uk/air___fuel1.htm.
