I'm pretty sure they come with a full log memory from the factory.
Also, just a gearing suggestion, I run that same exact setup with a 16t pinion. Went from 14 to 15 to 16 and that was best to me. I also run 10° to 15° of ESC timing and it rips. I temp at 140° to 145° after 10+ minutes. Outside the can temp. Data log temp is inside and about 50° higher.
Two different indoor tracks, both medium largish in size med/high bite clay.

Try custom lvc at 6.9 or 7 volt, you should still get a good solid 10 min and be nicer to your lipo. 2s lvc is too low for my liking but that's just me.
