It appears the temperature messages (EVcan 546
7 and CARcan 510
8) do not suffer from the same long delay/time_constant as the dash eyebrow display. I added the ambient to the debug screen on CANary and although I am within 1 degree when the car is at equilibrium, the message is much more responsive to outside changes. I ran an errand this afternoon. When I left the garage (80F), CANary and LEAF dash matched. Within minutes of driving in 110F weather, the CANary (msgID 546/510) temp quickly rose to 109F
but the dash only increased to 84. I double-checked the owners manual and it is, indeed, supposed to be outside air temperature (I thought maybe it was showing cabin temperature). I wonder why the dash temp has so much filtering - makes it rather less useful. I think I will add outside ambient to one of the operational screens.
