Does the car give some clue when it shifts from Open Loop to Closed Loop? That is, some way the driver could definitively tell when that happens? On our old Protege5 I could tell by a change in the idle, but that only works if the car is sitting still, it would be nice to have this information when the car is moving. Failing that, any idea which of the huge number of displays available in Torque Pro (with the Prius PIDs added) will show this? I'm curious because the car seems to be slow to warm up, as judged solely by the change in MPG on the bar display. Might or might not be correlated with the OL to CL transition. Seems like it should be.
