Well, after a little more experimentation, I've found that I need to stay in gear in order to sustain the 9999 mpg reading...but then after it gets below a certain speed (or rpm), it seems to drop back down to like 50mpg again, as if i were coasting in neutral. Is this the fuel-cut off getting switched off? I put it back into neutral after it drops from 9999...but should i downshift instead? Would the A/C being on or off affect the rpms, thus affecting the time at which the cut-off is switched off?
Also, it seems that SG has a sort of delay in displaying fuel economy in realtime...I think it might be a full 1 second delay. Does this happen to everyone?
Thanks.
