I see now the process - thank you for explanation, ok - with exception that transmission kinda a doing same jerking going on (when you at neutral, car still stops after injecting) and process of charging battery?!?
But for the first injection time mostly and then only battery working.
That's additional screenshots from the start "cold" car. 45F out.
As gasoline is on & up and battery as charging and you are saying -the ICE heat coolant and cabin. Why is battery could do that? May be physic or mystery for me. ;-)
