MAP based (Speed Density) fuel systems & IAT temps

How large of a factor does the IAT play in a MAP based (Speed Density) system? With the recent warm up, my IAT has shifted from its winter value of 80-90F to a spring-summer value of 100F-130F and I have noticed no change in fuel delivery :confused:

For hondas the difference is just a few percent in the normal range, I posted up a graph way back when that you can find if you search around.

If you'd like, I can email you the section of the OBD manual that discusses IAT influence on the entire system on a Honda.
