Ive fooled around with the gen 2 insight and it seems best mpg is from not using the ima system and like using cruse control for constant speed.
Actually I have to replace one of the O2 sensors, I have the CEL on right now and I'm not getting lean burn at all. So the decent numbers I've whistled up these past few tanks have just been from technique. Gotta get the heat shield off the cat so I can put a real wrench on the sensor, the silly split-socket just spreads and starts to round the corners. Can't have that!

Lead or follow. Either is fine.
