It's debateable, some ECU's won't advance the timing and only add fuel with a colder IAT reading, but some like the Insight will do both.
That being said, running 11.5-12.0 AFR is too rich, especially when it used to run 12.0-12.5... but heck getting 5 degrees more timing ain't half bad (assuming the knock sensor doesn't kick in).
