Extreme oil temps after ecu reset

GZ3

So I reset my ecu today to clear the loose gas cap code, my oil temps have never seen higher than 220. When I switched to synthetic oil (pennzoil ultra), my temps dropped even more down to 210-215 at the highest. I live in texas and drove to houston and back in 100+ degree temps with no issues. But today, after my ecu reset on a 12 mile drive back home from work in 95 degree temp, my oil temps soared to 250. 260!!!! This was the first drive since I reset the ecu in the parking lot! What the #uck happened?? The car is a 2010 with 2.5k.....this is some bs! Anyone heard or had this crap happen to them so suddenly, does the ecu monitor or regulate something regarding oil cooling? Thanks /end rant
