When resetting the ecu, does one do it when the engine is cold or already warmed up?

I don't know what the factory map is set for but I do know that the ecu will 'self tune' for various gas and air. As long as you don't put leded fuel in it, it should keep the advance higher with higher octane gas. If you put in leded race fuel in, it will mess up your O2 sensors and cause problems.
