Alright, I got a Kiwi 3 and Dash Command for my phone and started doing some data logging. Unfortunately for some reason the only data set that actually saved was from this morning, which is not very relevant since the ambient temp was only about 90 degrees and I wasn't experiencing any issues. But for reference, the IAT ranged from 115 when stopped to 104-108 when driving 45-50 mph. Is there a certain IAT threshold that is known to cause the ECU to start reducing power? I'll see what I get while driving around tomorrow afternoon.

No I don't but like I said, the oil temp usually reads 200-220 when I'm having these performance issues, and it rarely goes above there. From what I've read (and experienced via two test drives of new Zs in the same conditions), it seems like that should be fine...

Any tips on how to analyze/interpret timing changes? I have the data plotted but don't know what to make of it since I'm 100% new to this, haha.
