Wrong. Where did you pull that conclusion from? Cylinder temps are far beyond the vaporization points for either water or alcohol. How could you possibly harm the motor even with sub-zero IATs? You can inject too much and quench the combustion process leading to misfire and if you don't employ failsafes, I suppose even hydrolock is possible. But that's possible with a faulty fuel injector also. Bottom line is that with today's W/M injection systems, properly tuned, it's virtually impossible to harm the motor. They are great safeguards for the motor though!

Wrong. IAT and octane are completely different concepts but if you want to compare their relation to knock, IAT (intake air temperature) is exactly OPPOSITE to Octane. Higher octane decreases the predisposition to knock. Higher IAT increases the predisposition to knock.
