Running an engine too cold is indeed a bad thing!! The worst situation you could find is that you're constantly running rich, you could even be "washing" the bores with fuel. If the engine is cold, the computer knows it, and sets timing and fueling accordingly. It's also less efficient, therefore worse for your pocket and worse for the environment. If Porsche, with their millions of Marks investment, designed the engine to run at 180 degrees, then thats what it should run at!!
