My MPGuino is also rock-solid accurate. I have an UltraGauge (cheaper and flashier version of the ScanGauge), and it will vary wildly in its tank fuel economy calculation. It'll tell me that I get anywhere from 19 MPG to 22 MPG, when the MPGuino (and my tank calculations from each fill-up) will reliably report 24-25 MPG.
