Weird (?) coolant temp fluctuation
Data: 1.6 engine, td04 14psi, 42mm alu rad ducted, reroute, std Tstat. eMS2.
look how temp go up and back drop in a small time, is that normal?
i am looking to improve cooling as i use to track it, but i am having overheating in 2/3 fast lap, 110/120°C with 30°C outside temp, maybe obstructed coolant holes in the engine or poor water pump working?

Well, I already screwed you once, so here goes . . .
Like Niklas said, it REALLY tracks the duty cycle trace (I wish your original graphs had shown duty cycle). I would be cleaning and refastening all engine grounds before doing anything else. I don't think what you're seeing here are real temperature fluctuations.
Sorry about the bad advice earlier. If it makes you feel any better, I'm pretty sure you would have eventually encountered head gasket issues with track driving. I sure did.
