Bob,

I've been playing with my CIS today and because the ambient temperature is so much colder than it was earlier this year I'm noticing a greater effect of the "warming up phase". I get the feeling that your resistor shunt of the coolant sender has had a big effect.

I'm going to spend a bit more time tomorrow sending in different resistance values to check what is going on.

What was the value of the resistor you added again?
