The Insight loves the heat, and I'd like to know why. You can get into lean burn much sooner in 90°F weather than 70°F, and I see an improvement in FE that air density alone can't explain.

I've been thinking about replacing my ambient air temperature sensor (an IMA system input) with a resistor corresponding to ~150°F. I'd like to find out if a coolant temperature sensor lie-box would also be helpful.

Now, Propane, if your 3kOhms adds 30°F during the summer, what's it going to do in the winter?

I'm also very curious about how rough my precious, sensitive Insight will run when it misjudges the coolant temperature. I guess we're going to find out.

P.S. 0 Ohm pot in parallel = instant CEL, yes? Coolant temperature sensor reporting absolute zero.
