MSI V3.0 MSnS-e029q2

My AFR is perfect if my engine temp is below 190deg F. Above this temp my EGO goes lean. In the Advanced settings of Megatune this can be adjusted % up/down. The manuel does not say which way to adjust for more fuel at a given temp. In the morning and evening the AFR is perfect, during the day ambient temp can rise above 100deg F. this in turn makes my CLT & IAT rise leaning out my engine. I live in California, at sea level. The Megamanual only describes these sensors and does not address how they function with Megatune. Please help!

OK, I contacted Phillip at the Extra siteand was told to adjust % up for more fuel at a given temp. It's very hard to dail in VE when the tempature swings low/high during the day. This may seem silly but the megamanual does not describe this feature at all.
