That is assuming a lot. Do you have anything to back this up? AFAIK IAT is not a primary determinant of timing.

The work around this problem would be to manually control the input form the AIT sensor in order to trick the ECU to advance timing. This seems extremely dangerous to me.
That is hardly dangerous unless you floor it, and is a non issue with knock sensor equipped cars.
