Yes it's a pitty that airio don't get updated anymore and some things don't work properly. But I feel airio is still most complete lapper and we are able to ad new cars and tracks. But then I tried lapper somewhere 2011 / 2012 maybe it's more complete now
Didn't know that cntrl shift different temps. But I doubt it's surface becourse those temps also get hotter every every lap. In a xrg temps about 3 degrees below tire temp.
