A few weeks back when i went and got only 1 run in due to rain out, I had some Sunoco Maximal. That's 116 octane. I didn't have any problems then. I only had a couple gallons left so i just mixed it in with the CAM2 112oct.
Probably engine temp is all i can assume at this point.

If your knock count is high and your coolant temps are high your are detonating, turn the boost down, octane up, or timing down.
Great run's, it is awesome to reach goals (I hope I hit mine this weekend).
