Isaw it once before but I cant find it now but does anyone know what they call that electronic guage that plugs into your ODB II computer connector and gives you read outs such as fuel economy and so forth. I thought the name was something like Smart guage III but in doing searches for it under this name nothing comes up that is even remotely close.

 

Thanks all but someone on another forum found it for me. it is called ScangaugeII and monitors many different guages.
