Well, at least I found out something new about Bit’sBox, my van, this morning.
I’ve mentioned in previous postngs that it has a Temp readout that’s connected directly to the master ECM. You are told what temp the Engine thinks it is outside as you drive, which is as close to accuracy as no matter for the purpose.

The new bit of information is that it does read temps that are below Zero.
About that; It’s not even winter for another 24 hours, yet…
