I'm not sure just why it doesn't work well. My guess, from what other people have said, is that unlike the OEM gauge, it is not measuring actual fuel flow, but using some algorithms to estimate it. That may work ok for "normal" cars, but I think the Insight just goes too low, as it were. For instance, the SG's fuel flow only reads in tenths of a GPH, and I could never get it below 0.2 even when in open loop and DFCO. There are also a bunch of parameters that have to be set (like displacement & number of cylinders), which the SG keeps forgetting...
