^ I'm thinking that disconnecting the outdoor air temp sensor, or replacing it with a resistor that spoofs a cold temp, is the thing to do or that's done to disable auto-stop.
Why would that be the case? If QBATT is low, wouldn't the car then be trying to charge the pack off the ICE all the time - with an mpg penalty? IF disconnecting the outdoor temp sensor does indeed disable autostop, why would there be a fuel economy penalty for that but not with using QBATT?The most fuel efficient way to disable autostop is to change the QBATT signal to "battery is empty".
Ah, OK, that would make sense... Seems like it might be hard to...model the conditions for when AS should be occurring...The QBATT signal would only be set to "empty" when the conditions for autostop to occur existed... under normal conditions (i.e. when the ECM wants the engine to be on) QBATT would pass through as-is.
I'm under the impression that the outdoor air temp sensor goes directly to climate control and is only used for CC. I must have read that around here at some point, eons ago. But I don't know whether that's true first hand. It seems like it would be true, or rather, it seems like the ECM would rather use the intake air temp sensor and/or engine coolant temp for engine fuel trim, or whatever.I believe the problem with disconnecting the outdoor temp sensor is that the ECM trims the fuel more rich (i.e. limp-in/cold mode). If that's not the case, then yes, disconnecting the temp sensor would work.
